I called to get imformation about a weight distribution hitch. William B had all the knowledge I needed and helped me through the hitch with part numbers and measurements and we compared pictures on email and he found exactly what I wanted and ordered direct from him. Very knowledgeable and helpful. Very friendly. I will do business there again

Am quite happy with eTrailer. Their website provides more detailed info than the manufacturer's! Getting ready for the summer boating season... Needed a longer hitch bar so could open tailgate with trailer hooked up. This was exactly as specified and works great. Have used eTrailer several times now and service has always been among the best...quick, accurate, and good prices.

I normally tow my vintage Airstream with a vintage, 3/4-ton Suburban whose 7.4l engine has quite the taste for mid-grade gasoline. Economics has forced me to consider towing with my wife's '09 Yukon which has an incredibly high receiver hitch. Etrailer had just the shank I needed (the black part in the picture) at a great price to make everything work. And it got here quickly. I'm now literally a happy camper.

Found what I was looking for. Fast free shipping

Needed this for my Reese SC weight distribution hitch. It was a necessity due to how low my 2012 jeep Srt8 and haulmark low hauler are to the ground. Great customer service and fast shipping.
by: Gary 03/28/2023
The tongue of my trailer is pretty low so the standard shank wouldn't allow me to set my new hitch up properly. This shank was just what I needed.
by: Dan03/25/2018
Worked great. The pictures show how the extra length that is given. In my case I needed 2 more mounting holes down. This one gave me 3. I needed after I moved to a 4 wheel drive truck.
by: Hal 03/31/2023
Nice hunk of a shank! I needed to drop my ball height a couple of inches lower than stock and this was just the ticket. I could have saved a few bucks and gotten the welded up shank but I like the higher weight rating of this baby. A little more piece of mind when traveling down rough roads!
by: Charles S.06/05/2015
We bought a new pick up truck that sits 6" higher than our old truck. This draw bar has a greater drop than the old one and allowed me to use the rest of my weight distribution hitch.

After using the draw bar for a year with my 24 Haulmark Edge trailer, all is well. The trailer sits level, it tows great, the weight distribution system works as designed. Im happy.
by: Peter S, Florida02/04/2014
My trailer sits very low by design. When towing it tows with the tail down. Not a performance issue at all. But it looks funny. I needed to lower the ball 2 inches for it to look sharp when towing.
The Q and A at etrailer had a video showing all of the dimensions. This made my selection of this drop shank certain.
Product arrived in just a few days. thanks etrailer

The ped shank has worked perfectly. The trailer tows level reducing the amount of the trailer front surface from the wind resistance.But the best part is the trailer looks so sharp being towed level.I am looking forward to shopping a E-trailer in the future. Thanks
by: Dennis 11/23/2022
I have traveled about 5,000 miles with this shank and have had no issues. Tow a 30-foot travel trailer with a 2500 Duramax. The long extension and drop range are perfect.
by: Brad06/25/2016
This is a heavy shank that is needed for our trucks height. The bottom 2 bolt holes brings the ball to the right height for the camper which was riding to high on the previous shank. E-Trailer was very quick to ship as it only took 3 days from ordering to install. Very good company to shop with!

Its been 1 year on this hitch setup and a good one also. This hitch system is better performing than the friction sway control we had previously as it out performs the old system drastically. It actually wants to correct wind sway the way sway controls should! The only option I should have gone with is getting the 2-1/2 in shank instead of the 2 shank.
by: Kevin 03/07/2023
I needed a shank with a lower drop to accommodate a new 4x4 truck towing a camper. This fit the bill perfectly. I have not tried towing yet but I expect it to be successful.
by: Carl B.08/05/2016
After upgrading from a 1500 to 2500 Ram 4x4 I needed a shank with a six inch drop to use with my 49901 Pro Series distribution hitch. The RP63971provides enough drop and also moves the ball away from the bumper a little more allowing additional clearance for the tailgate when it is open. This shank is lighter than the one I replaced due to the U shape of the section where the ball mount bolts on. That's a plus, but because of the U shape you cannot use the angel adjustment rivet, washers and set screw that are used with the 49901 hitch to lock in the angel of the ball mount. I had concerns the tension on the bolts holding the ball mount on would not be enough to maintain the correct angle so I took a piece of 1/4" steel plate 6" long and slipped it in between the ball mount and shank. This provided a solid stop for the rivet and set screw.

Exactly what I needed to get my truck and trailer level again after my new tire upgrade. Everything trailer comes from you guys.

As good as the day I wrote the review and as I stated everything trailer comes from etrailer. Just added a second sway control to my setup since we have a 26+ pull behind. Best company and service hands down.
by: Robert C10/08/2019
This one fit my trailer exactly as needed. The one I purchased just prior didn't have enough drop, my fault for not measuring things right.

Works great.
by: Mike10/01/2018
I purchased a new 2017 ford f250 to pull our 32 ft bumper pull camper. I noticed I had some trailer sway at highway speeds and the ball was just too high. I had no more adjustment on the shank I had. This one I purchased gave me extra adjustment and now the trailer tows perfect. The shipping was really fast. Also for pet owners now my tailgate can drop down so the dogs can jump into the back of the truck while the camper is hooked up
by: Brian L. 08/08/2016
Had to move my trailer hitch for my camper from my 2 wheel drive F150 to my new 4 wheel drive Ram 2500. This part was needed to get my camping trailer to run level. Perfect part for the job
by: Bob S03/29/2012
When I switched to a bigger tow vehicle I needed a longer shank to increased the hitch drop another 2.25 inches to keep my trailer level. The detailed info on the product page gave me what I needed to know -
63971 would provide the drop I needed but would not be too long to cause bottoming-out concerns. After installation the hitch mount sits at the desired drop and still has 2 adjustment holes at the top of the shank and 1 at the bottom - perfect! Also, ET's price + shipping was very competitive and delivery was prompt.
by: Steve10/13/2021
Unfortunately, etrailer sent the wrong size. Fortunately, they will send the correct size. I had originally called them and explained that my TT's tongue was too short and the TT was hitting & breaking my taillights. A nice person checked what I might need and said a longer shank would work--RP63971. Unfortunately it was not the correct information and the shank that I was told would work, was not the best one for my application. I found a shank that would appear to work better. etrailer will be sending that longer shank (EQ90-02-4500 when they get it at the end of November). The return guy understood what the problem was and said just return the one I didn't want. No hassle.
by: Justin 06/10/2014
with a higher truck and a lower camper the hitch I was sold from the dealer did not work I bought this from E-trailer to fix my problem of the camper not being level. I expected to get this within 7 to 10 days and I had it in two I would highly recommend E-trailer to anyone and if I ever need anything for the trailer again I will be getting it through E-trailer.
by: Dennis K.01/07/2017
This also replaces my hitch that was stolen which also was a Reese. This has enough drop for my Ram which sits pretty high. I have to say something about Etrailer. I deleted all my other trailer supply stores because these people are top notch in quality, prices, and shipping. From now on I'll order all I need here and I'll be in the market for a roof kit next summer. Guess who gets that order?
by: Greg B.12/19/2016
I used this shank to pull a travel trailer with a weight distribution hitch that required a deep drop.
by: Tom06/10/2022
I needed a shank that allowed a greater drop for my weight distribution hitch. Finding the right one was not easy. Paul was extremely patient and really helpful in finding one that would do the trick. The new one is perfect. No one has better service than etrailer.
by: James V.06/30/2015
This is an update to my previous review of this product. After calling Reese Products (which is a Cequent Company) they explained that is item is from another Ceguent Company being sold under the Reese name. It is really a , "Ultra Frame" product, Made in China. etrailer is not misrepresenting the product as a Reese product, Cequent is now marketing a Chinese version under the Ultra Frame brand. I would assume it's cheaper for Cequent to source the product out of China instead of the USA where I'm use to seeing Reese products.
Reese products carry a one year (or longer ) warranty, I have no idea what the warranty of this Chinese version is. It does not fit as well in the receiver as my other Reese products (wobbles side to side). The fit and finish is not as nice, you can see welding marks grinding. And, considering all the " junk" and counterfit products that China is importing into the USA, I'm not surprised that Cequent, used another brand name to import this part

- Weight Distribution System for a 2005 Dodge Ram 2500 Quad Cab 2wd Diesel Pulling a Car HaulerThe important factor to consider when choosing a weight distribution system is the loaded tongue weight of your towing setup. The loaded tongue weight includes the loaded and ready to tow tongue weight of your trailer plus the weight of any cargo that is loaded in your truck bed behind the rear axle. Once you find the loaded tongue weight of your setup, you will want to choose a weight distribution system with a tongue weight range that encompasses your loaded tongue weight. I have attached...
view full answer... - Weight Distribution Shank Compatibility With Pro Series Weight Distribution SystemMany weight distribution shanks will be interchangable with your ProSeries weight distribution system. The only thing you need to do is match the style of the shank. So if it is a channel style, you will need to get a channel style drop shank like # RP63971. If it is a regular shank you can use a traditional style drop shank like # C17123. If it has a vertical groove, you will need the vertical groove like # RP54998. Other than style, you will just need to get compatible weight rating...
view full answer... - Strait-Line Weight Distribution Shank and Trailer Ball for 2006 Dodge Ram Towing 8000 lb Toy HaulerThe Strait-Line Weight Distribution System, part # RP66074 would be ideal for your vehicle/trailer set-up. With an 8000 lb trailer, tongue weight is typically figured as between 10 to 15 percent of the trailer weight. Even if the tongue weight of your trailer is closer to the high side, you will have enough capacity in the system. To make an approximate determination of which shank is needed, jack up your trailer so that it is level, and measure from the bottom of the coupler to the ground....
view full answer... - Is There a Weight Distribution System With a 3-1/2 Inch Drop To Level a TrailerYou are not misinterpreting the specs on our product page. Those are the rise and drop measurements of the shanks that come with the weight distribution system. You can purchase a separate shank like the Reese Weight Distribution Shank, # RP63971, that can adjust down to a 5-3/4 inch drop and can also accommodate the 3-1/2 inch drop that you need. This shank will also support up to 1,500 lbs of tongue weight. For your 10,000 lb trailer, I recommend the Reese Steadi-Flex Weight Distribution...
view full answer... - Availability of Drop Weight Distribution Shank with 2 More Inches Drop than Reese 54917For a shank that will fit your Reese weight distribution system and will be right at 2 inches of additional drop you'd want the Curt shank part # C17124 which is compatible with your Reese system and would fit and work well.

- Longer Weight Distribution Shank Needed for the Curt # C17002We do have a variety of weight distribution (WD) shanks that you can swap out with the shank you are using for the Curt # C17002. One of the most popular options that we carry is the Curt # C17123 which has a 7" long shank and allows you to adjust your round bar system to a max 8-1/2" drop or a max 12-3/4" rise. I have also attached a link to our selection of WD shanks that are compatible with a 2" hitch receiver. As long as they have a squared side and don't slope down like part # RP63971...

- Longer Weight Distribution Shank to Tow with Tail Gate DownWe have a few options that may work for you. You didn't say exacty how much longer you need the shank to be and I don't think we have one that fits every piece of criteria you're looking for but here's some ideas that could fit: Part # RP63971 is 14 inches long overall. The drop is only 6-1/2 inches and that's with a round bar weight distribution system. If you have a trunnion bar system it won't work because the drop is only 4-3/4 inches. It's also for 2 inch receivers so you'll still...
view full answer... - Can Weight Distribution Shank be Used Upside-Down to Keep Trailer Level When HitchedAs long as your particular weight distribution shank is not specified as being for Rise-Only or Drop-Only use then it can be used in an inverted position to give you the height adjustment you need to keep your trailer level. For example, Reese Weight Dist Shank # RP63971 must be used in the drop position only while # RP54970 can be used in either the rise or drop position.
view full answer... - Would the Reese Weight Distribution Shank Part # RP63971 Work for 5 inches of DropYou are correct, there will be a slight squat to your 2011 Dodge Durango suspension when the tongue weight of your 2011 Airstream Sport Bambi trailer is on the hitch. The Reese Weight Distribution shank part # RP63971 that you referenced should be perfect for you since you said you need a 5 inch drop and this will do 4-3/4 inches of drop with a trunnion system like yours. I attached a review video for this ball mount, and FAQ on weight distribution and an FAQ on determining the correct...
view full answer... - Weight Distribution Shank to Allow Additional Drop with Reese Weight Distribution SystemSounds like you are in need of a weight distribution shank that will provide you with 4 inches of additional drop from what you have. A great solution for that is the Curt weight distribution shank part # C17123 which will give you the amount of drop you are looking for and also fits the head of your Reese system since Curt and Reese both make their shank dimensions to the same size.
view full answer... - Replacement Weight Distribution Shank for Reese Strait-Line SystemReese weight distribution shank # RP54970 provides 1-1/4-inches of drop when used with trunnion style bars like those in the Reese Strait-Line Weight Distribution system # RP66074. It sounds like you need a shank that will give you more like 4 or 5-inches of drop. Pro Series, sister brand to Reese, offers their shank # RP63971 which provides 4-3/4-inches of drop when used with trunnion style bars. Reese part # RP3215 will also provide enough drop but it's overall height of 12-inches will...
view full answer... - Weight Distribution for a Car Trailer with a Channel Coupler 4 Inches Higher than the Trailer FrameThe way I would go about this is to lower your coupler height or use a coupler similar to the Bulldog Collar-Lok Coupler w/ Pin - 2-5/16 inch Ball - Adjustable Channel Mount - 12,500 lbs, item # BD028585, and mount it so that the coupler is in the correct position to allow a weight distribution hitch to be used with the trailer and coupler. Make sure the coupler you select will accommodate the total weight of your trailer and the loads on it. You would then use a weight distribution system...
view full answer... - Weight Distribution for a Trailer with Varying Tongue Weight from 400 to 1,500 PoundsNo worries, I can help you out with this issue. It is a common question, a varying load. There are weight distribution systems that have a tongue weight capacity range. The widest range is 600 to 1,200 pounds. There is also an 800 to 1,500 pound system. Considering that you can potentially have 1,500 pounds tongue weight you will need a system that goes at least that high. There is a Blue Ox system, # BXW1500, that is rated for up to 1,500 pounds tongue weight and requires a minimum of...
view full answer... - Will The Reese Pro Series WD Shank Work With A Reese WDS?Yes, the Pro Series Weight Distribution Shank # RP63971 will work great with your Reese WDS 54947! This weight distribution shank will work with 2" trailer hitch receivers, has a maximum tongue weight capacity of 1,500lbs, measures 14" long, and features 4-3/4" to 6-1/2" of drop depending on if you're using a trunnion setup or a round bar setup. Attached is a product overview video of # RP63971 for you to check out as well.
view full answer... - Weight Distribution Shank Needed with 6-1/2 Inch DropRise and drop is measured from the top of the receiver opening to the top of the ball platform. If you flip your shank so that it points down you should be able to get a little more drop out of a system when the head is bolted on in the lowest position. If that is not enough then there are other shanks available with more drop. If you have a Pro Series system with round bars you can use shank # RP63971 which has a maximum drop of 6-1/2 inches. For Trunnion style bars you can use shank...
view full answer... - Will The Reese Weight Distribution Shank Allow Low Enough Drop And Level Truck and TrailerThe item you selected, Reese Weight Distribution Shank, part # RP63971 does have a lower drop than part # RP54970, but you will need to measure to determine which shank you will need for your towing setup. To do this, there are a few steps involved. First, you will need to measure from the ground to the top of the receiver on your trailer hitch. Then, while your trailer is not connected to the vehicle and is on level ground, measure from the ground to the bottom of the trailer coupler. Now...
view full answer... - Excessive Trailer Sway Towing 32-Foot Travel Trailer with 6-Inch-Lifted Ram 2500 with 37-Inch TiresMy technical contact at Reese confirmed that using a properly-rated and -installed weight distribution/sway control system such as the Reese Dual Cam should provide some reduction in trailer sway. You are correct that the sway you are experiencing when towing with your lifted Ram 2500 with 37-inch tires could be a result of the altered geometry in the tow vehicle, in particular the higher center of gravity. If your current weight distribution set-up has your trailer out of level when hitched...
view full answer... - Weight Distribution Shank Recommendation for a Pro Series System Where More Drop is NeededTo determine exactly how much drop you would need out of a shank check out the FAQ article I attached that details exactly how this is determined. The current shank you have will give you at most a 2 inch drop. For an additional 4-1/2 inches of drop capability check out the Reese Weight Distribution Shank part # RP63971. This shank can do a total of 6-1/2 inches of drop and should work well for you. I attached a review video for this product for you to check out also.
view full answer... - Weight Distribution Shank with More Drop for Pro Series System # PS49901Reese weight distribution shank # RP63971 has a maximum drop of 6-1/2 inches so if that is enough drop you can use it. If you need more shank # RP3344 has a maximum drop of 8-5/8 inches. The height adjustments are in 1-1/4 inch increments. I have included a link to our ball mount FAQ article that you can use to determine the drop you need.
view full answer... - Weight Distribution System Recommendation for 2009 Keystone Sprinter 311BHSThe best way to pick out a weight distribution system is to base it off of the loaded tongue weight of the setup when it is loaded and ready to tow. This figure also includes the weight of any cargo behind the rear axle of the tow vehicle. I attached a help article on determining tongue weight for you to check out as well. You will want the loaded tongue weight of your setup to fall right in the middle of the tongue weight range of the system you use. So your tongue is realistically going...
view full answer... - Can Convert-A-Ball Ball Mount Adapter Be Used with Any Weight Distribution ShankThe Ball Mount Adapter # BA-1 can be used with any weight distribution shanks with 3/4 inch shank diameter and holes 1-1/4 inch apart. Which is the standard. The only shank type you will not be able to use it with are shanks with a hollow channel, such as part # RP63971. The holes will not line up with the holes on the adapter. But if you stick with a solid design like the # AMAC1 you'll be just fine.
view full answer... - Recommended 6 Inch Drop Shank For Reese SC Weight Distribution SystemFor your system, I recommend the Pro Series Weight Distribution Shank - 14" Long - 4-3/4" or 6-1/2" Drop - 1.5K TW # RP63971 that will give you a drop of 4-3/8 inches from the top of your hitch receiver opening. This drop shank is designed for this system. For a larger drop without losing capacity, you can use the Curt Welded Weight Distribution Shank 7" - 10 Hole Adjustment # C17123 which will give you a 8-1/4 inch drop but will also move the entire system much closer to your hitch...
view full answer... - Will Weight Distribution Help Level a 2009 Ford F-150 Pulling a 10,000 Pound Dump TrailerA weight distribution system will certainly help level the load and keep the truck from sagging. As you probably know the suspension on an F-350 is quite a bit heavier than that of an F-150. A weight distribution system will allow the truck to pull itself back up to level. For a trailer that weighs 10,400 pounds, I would recommend the Reese High Performance Trunnion Weight Distribution system, part # RP66022. It has a maximum gross trailer weight capacity of 12,000 pounds which is enough...
view full answer... - What is the Best Weight Distribution and Sway Control System for a 8,200 Pound Travel TrailerWe will plan for the maximum gross trailer weight of 8,200 pounds. The dry tongue weight, 910, is right around 15 percent of the 6,300 dry weight. We can then estimate at 8,200 pounds trailer weight our tongue weight is 1,230 pounds. Since your tongue weight will be somewhere between 910 and 1,230 pounds, Reese Strait-Line Weight Distribution system, part # RP66074, would work perfect for you. It has the Dual-Cam Sway Control System which is the best system for a larger trailer, especially...
