by:

Very happy with this hitch. Finish has held up well and is a very beefy addition to my 03'Duramax. Allows me to tow my heavy trailers without fear of breaking my factory hitch again (twice now).
Fairly easy to install as well.



by:

The product itself is great.! Will likely order a second for my other truck. I’d give it a 5/5 stars, Worked phenomenal on a long trip! Easy to install by yourself. However it came damaged, box rubbed/ripped through and the powder coat rubbed off in multiple places and when I reached out to try and get a replacement got nothing so I went ahead and installed so I could make my trip.



by:

Dealing with etrailer was a breeze! Nice well built receiver hitch, heavy duty. Took less than half an hour to install including removing the old hitch. I will definitely recommend etrailer.com.



by:

I almost didn't buy it from the reviews saying it hangs lower than the oem one. I'm very happy I did, its a nice hitch. Yeah it hangs a little lower but it's negligible cant even tell. Buy it....

2005 GMC Sierra

When I discovered that my factory installed hitch was only rated for 7500lbs I knew I needed something different. Etrailer came through again. This hitch is exactly what i needed. My camper has a GVW of 12K and i have the weight distribution hitch. Easy to install and the 4" drop just what i needed to lower my bumper also.



by:

Heavy Duty hitch and was easy to install. I really wish Curt would have extended the hitch further out as I can no longer carry my full size spare. I have 35" tall tires and I no longer have the room to carry the spare. The distance between the differential cover and hitch is shorter than the OEM hitch.

The hitch is well built and has served me well.



by:

Was actually shocked at how heavy duty this thing is. Took under an hour to install.

THE BEST SERVICE BY FAR!!!!!
I went through
3 different companies before contacting etrailer, they was very patient with me and went over everything to make sure the order was right.
I ordered it and asked for quick shipping, something almost no one offers on parts like this and BUT they have 4 DAY SHIPPING for only around $40, you can’t beat that!!! I ordered it Thursday, they said it will be here Thursday or Friday of the following week and it was here the following Tuesday!!!
Very quick and easy install.
I have 3 Curt Class V Hitches by the way.
one on the Chevrolet,Ford and Ram.

Thanks again for the Great service, y’all have a permanent customer.

AND THEY GIVE YOU STEP BY STEP DELIVERY PROGRESS!!!



by:

The trailer hitch is a super heavy duty trailer hitch. The only problem with the trailer hitches is very heavy to install underneath of the truck. I have a truck with a 10 inch drop bumper they was after market and they research the trailer hitch and said it would fit and it fits great love the trailer hitch installation had all the right Hardware all grade 8 bolts nothing cheap about it love it

Been using for a year the hitch is great.the paint is still in gear condition no peeling,or rusting.the hitch has handled everything I have hooked to it .



by:
2006 GMC Sierra

Looks like a well built hitch,installing over the weekend.



by:

Product arrived in a damaged box and had some scratches in various places. Packaging could have probably been more robust.
Other than that, the installation was quick and straightforward. Unless you regularly bench about 100 pounds, you'll need some assistance. Have yet to tow with it, but it should work just fine. Much better than the stock hitch that failed which prompted the replacement. 03 GMC Sierra 3500 CC Long bed, Dually, 6.6L.

I will have our customer service team reach out to you. I recommend using a rust resistant paint to touch up the hitch. You will then have the paint on hand for regular hitch maintenance.

Still an excellent product and still highly recommend it!

Towed a lot with it and still working great, zero complaints.



by:

It easily bolted on to my 08 Silverado 2500HD. The floor of the 2 1/2" receiver hole is about 1" lower than the hitch (I think stock) I took off, but I knew that from reading other reviews.



by:
2005 Chevrolet Silverado

Great affordable hitch. Very easy to install. I installed it in about 30 minutes even without removing the spare tire. 05 3500 Silverado



by:

Great customer service. Product performs as should. Easy installation. Huge upgrade to the stock tow package, that had rusted through on my 08 silverado



by:

Great hitch and perfect fit for my truck. Was really a 2 man job but got it done by myself. The factory hitch is kind of a pain to get off on the 2008 HD as there are bolts up right at the bumper line.

The new one fit like a glove i did add to shackles to allow my safety chains to attach a little easier. Great product great customer service. etrailer is the best i love these guys have bought lots of stuff from them and will definitely continue to buy more. Thanks



by:

Hitch receiver fit perfectly just as described, these folks give you step by step directions for start to finish install which expedite your entire process. Ordered Monday here on Wednesday! 11/10



by:

First off I am becoming a huge fan of E-trailers! I destroyed the stock hitch on my 02 Silverado 2500HD and was stressed about getting another hitch and having to wait for shipping. Not that this will happen every time but it was on my door step 3 days earlier than expected. The hitch fit great and was easy to install. I didn't realize how light duty the stock hitch was until mine folded in half while towing my equipment trailer. This Curt hitch is a huge upgrade and gives me peace of mind now when hauling heavy loads. Couldn't be happier!!!



by:
2021 Forest River Cherokee Wolf Pack TT Toy Hauler

This hitch receiver is built very well and bolted right up to the frame. Should be able to tow my 38' toy hauler with no issues with this thing. Just wished they provided the most rearward bolts and nuts if you have an off road bumper that doesn't require the bottom rear bolts for a stock bumper. It's also pretty heavy, definitely a two man job. All in all, great receiver.



by:

This is one duty receiver. One piece hitch with all hardware included. I installed in my driveway in 25minutes with only basic tools needed. Hangs about 4" lower than stock receiver but eliminated Need for drop hitch



by:

Best experience I’ve ever had ordering a product. So easy to see where your package is thru the whole process. Great staff



by:
2005 Ram 3500

Nice quality hitch easy install. Fast shipping. It sits a little lower then the factory hitch on a 2005 gmc 3500, so may want to double check if that may cause you an issue



by:

Install went well very happy with product, electrical receptacle bracket needed a little modifyingBy pulling the bracket out word and changing the angle had to trim a little plastic off the bumper



by:

Hitch arrived in a timely fashion with no shipping damage. Fit great on my hauler. Best shipping tracking that I have used! Will definitely recommend!

Needs better packaging! The box came m angled

  • Can Longer Hitch Extender be Used on a 2006 Chevy Silverado 2500HD
    If you have a 2-1/2 inch hitch on your 2006 Chevy Silverado 2500HD like the Curt hitch part # C15703 then you could use a Titan hitch extender like the part # RP45292 if you used it in the 24 inch length and used a weight distribution system since a WD system gives the extender a higher towing capacity of 8,000 lbs instead of 6,000 lbs. For a weight distribution system the part # RP66084 would be a great option. It has a tongue weight range of 600-1,200 lbs and features only sway control...

  • Recommended Class V Trailer Hitch for a 2005 Sierra 2500HD
    If you are looking for the most heavy duty option for your 2005 GMC Sierra 2500HD with an 8 foot bed, I suggest the Curt Class V Commercial Duty - 2-1/2" # C15703. This will have a 2,700 pound tongue weight and an 18,000 pound towing capacity.

  • Hight Capacity Trailer Hitch for 2003 GMC Sierra 2500HD without Rear Bumper
    Since the hitches we offer for your 2003 GMC Sierra 2500HD attach to the frame and not the bumper they will all still fit and work great. The Curt Class V hitch # C15703 would be an excellent option as it has plenty of weight capacity as it's rated for up to 18,000 lb trailer weight.

  • Rear Torklift Camper Tie Down for 2008 Chevy Silverado 3500 with Curt Hitch
    It sounds like you are looking for a rear set of camper tie downs for your 2008 Chevy Silverado 3500 dually with the Curt hitch part # C15703. For that we have the Torklift set part # TLR3501 which I confirmed with Torklift as a fit.

  • Recommended Trailer Hitch Receiver and Wiring for 2005 GMC Sierra 3500
    Your 2005 GMC Sierra 3500, if you can handle a towing rating of 16K then I recommend the Curt Trailer Hitch Receiver - Custom Fit - Class V XD - 2" # C15312. If you need the larger capacity then you will need the Curt Trailer Hitch Receiver - Custom Fit - Class V Commercial Duty - 2-1/2" # C15703 but you will use a different ball mount or likely weight distribution system shank for this hitch. For your wiring, I recommend the Curt T-Connector Vehicle Wiring Harness for Factory Tow Package...

  • Can Curt Hitch C15703 Fit 2004 Chevy Silverado with Factory Hitch
    Someone was able to remove their factory hitch and install the Curt hitch part # C15703 that you referenced but they did report back that it was very difficult. If that's something you are okay with doing I am sure you'd be fine.

    Both of the Curt hitches that you listed are confirmed to fit your 2009 Chevrolet Silverado 2500HD. The difference between the two can been seen in these hitches' features. The Curt Class V Hitch # C15302 that uses the 2 inch receiver opening, is the hitch that I recommend. The 2 inch opening is the more common size for use of a hitch accessory. If you wan to use the hitch for this application, then you will have a wider selection of accessories that will fit this hitch/. This hitch...

    We haven't had the chance to install the Curt Class V Trailer Hitch Receiver # C15703 on the 2008 Chevy Silverado 2500 so I don't have exactly how far beneath the bumper the receiver will sit, however I did go out to our warehouse to take a measurement that will help you determine this. From the front bracket where the hitch will attach to the frame rails of your Silverado to the bottom of the receiver there is a distance of 9-3/4 inches. You can take this measurement down from the bottom...

  • Recommended Extended Ball Mount for 2 Receiver
    The longest hitch extender that fits a 2" receiver is going to be the 18" Draw-Tite Hitch Extender item # HE18. You would need to change out the hitch in your 2005 Chevy Silverado 3500 to the Curt Trailer Hitch item # C15703 to use the Hitch Box Extension and Reducer for Titan 2-1/2" Trailer Hitches item # RP45292 as it only fits 2-1/2" hitches.

The distance between the vertical mounting holes is 14-1/2" center to center, and the horizontal mountings holes are 39" apart center to center as shown in the included diagram.

  • Dimension of Curt Class V Hitch for 2002 GMC Sierra 2500HD with After Market Bumper
    Good news, I was able to go out to our warehouse and measure the Curt Class V Hitch # C15703. This Class V Trailer Hitch has a dimension of almost 5 inches from the top of the bolt holes to the top opening of the receiver hitch opening. This should accommodate the space you require for your after market bumper. This Curt trailer hitch will fit both the 6-1/2 and 8 foot bed sizes of the 2002 GMC Sierra 2500HD. I have linked an install video of the Curt hitch for your convenience.

  • Will Installing Curt # C15703 on 2006 Silverado 2500HD Interfere with Larger than Stock Spare Tire
    Curt does not have that measurement available, but you can determine this for yourself by taking some measurements from the underside of your truck. Using the diagram I edited for you, locate the weldnut that would serve as the rear-most attachment point for the hitch. From the center of this bolt hole, measure rearward toward the bumper six inches. From that point, measure forward to the closest point of the differential. If this distance is greater than the diameter of your spare tire,...

  • Heavy Duty Hitch for my 2003 Chevrolet 2500 HD
    After checking some information it appears that the maximum towing capacity of the 2003 Chevrolet 2500 HD is 12,000 lbs. This would be the max and depending on options it may be lower than that. I recommend using the owner's manual to determine exactly what the towing capacity of your exact configuration is. With that said the Curt Trailer Hitch Receiver part # C15703 is a very heavy duty hitch which will exceed your vehicle's capacity. The BulletProof Hitches Adjustable 2-Ball Mount for...

  • Class V Trailer Hitch Receiver for 2009 GMC Sierra 3500HD Work Truck
    The # C15800 is specifically designed to fit the cab and chassis models and is not a fit for your 2009 GMC Sierra 3500HD WT. The WT should have the same attachment points as the 3500 Pickup so the Curt Trailer Hitch Receiver # C15703 would be the correct hitch. This is also a Class V hitch with a maximum gross trailer weight of 18,000 lbs and max tongue weight of 2,700 lbs.

    I checked with Curt and they list trailer hitch # C15312 as a fit for a 2005 GMC Sierra 2500 or 3500, 8 foot bed with factory cutout bumper only. If your truck does not have the factory cutout bumper then I recommend # C15703 (2-1/2 inch receiver opening). If the truck has the 10 inch deep drop cowboy bumper then I recommend # C15313.

  • Hitch Recommendation for a 2007 Chevy Silverado 2500HD with 2-1/2 inch Hitch Opening
    For your 2007 Chevy Silverado 2500HD you would want the Curt hitch part # C15703 as it has been confirmed to fit your vehicle and has a 2-1/2 inch hitch opening like you said you were interested in. I attached a install video plus a link to a page that has all of the ball mounts we carry that would fit the hitch. You would want to first determine the amount of rise/drop you would need to tow your trailer level and then select it from the filters on the link.

    The Curt Trailer Hitch Receiver - Custom Fit - Class V CD - 2-1/2" # C15703 for your 2004 Chevy Silverado 2500 HD does not come with any adapters. It sounds like you are interested in a reducer like the Curt Hitch Receiver Reducer Sleeve - 2-1/2" to 2" # C45405. This will allow you to use 2 inch accessories with your 2-1/2 inch receiver.

  • Exact Measurement of Receiver of Curt Trailer Hitch 15703
    I went out to the warehouse with digital calipers to get the exact measurement of the receiver of the Curt Trailer Hitch # C15703 and found it to be 2.55" though it is possible for the hitch that is shipped to you to have slightly (and by slightly I mean a couple hundredths or thousandths of an inch) more or less room in the receiver. There is always going to be some slight play but you can reduce this with the use of the Blue Ox Hitch Receiver Immobilizer II # BX88225 which is designed...
