Specially designed for heavy-duty towing, this fully welded trailer hitch receiver bolts onto your vehicle's frame with no welding required. Powder coated steel is sturdy and corrosion resistant.

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.



by:

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:

Fast shipping and great selection. Will do all my business her from now on.



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:

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:

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:
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!

  • 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.

  • Will the Curt C15703 Fit a 2004 Chevy Silverado 2500 Short Bed with Factory Hitch
    The frames of the 2004 Chevy Silverado 2500 HD with short beds aren't going to be any different than standard beds or those trucks with hitches already installed, you just would not be able to install this hitch receiver as part of a dual hitch setup. The Curt # C15703 does not allow for that setup and can only be used as a single installed hitch, but all you would need to do is remove your factory 2" receiver and install this one and it will work just fine. I've linked an installation...

  • 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.

  • Recommended 2-1/2" Trailer Hitch that Fits Right Under Bumper of 2010 Chevy Silverado 2500
    There are two 2-1/2" trailer hitch receivers available for your 2010 Chevy Silverado 2500, and in terms of the fitment you're looking for the best option is with the Draw-Tite # DT45517. Unlike the Curt # C15703 that you mentioned, the receiver for this unit will sit right up against the bottom of your truck's bumper like you are wanting. I have attached a customer-submitted image below of the hitch installed so you can see exactly how it looks. Draw-Tite is an extremely reliable brand...

  • How to Install a 48 inch Long Hitch Extension on 2005 GMC Sierra 2500
    For a hitch extension that long you'd have to have a 2-1/2 inch hitch installed on your 2005 GMC Sierra 2500 like the Curt part # C15703 which is a confirmed fit. Once that's installed you'd be able to use a longer extension like the part # RP45018 which measures 48 inches in length.

  • 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...

  • Drop of Curt Class V Trailer Hitch # C15703 for 2007 Chevy Silverado Classic 3500
    From the underside of the frame to the top of the crossbar tube would be 5.13 inches, and from the underside of the truck frame to the lowest point on the hitch, which is the bottom of the side plates, is 9.83 inches. You can see these dimensions on the photo I've edited for you. I've also linked to an install video for you.

  • 2-1/2 Inch Class V Trailer Hitch for a 2000 Chevy Silverado 2500HD 6.0, 5-Speed, 14 Bolt Rear End
    The 2000 model year was a split model year for GM trucks (actually it started for the 1999 model year but continued until about 2002). This is when they went from being C or K series to being badged as Silverados/Sierras. So the issue with filters and whatnot may have stemmed from that. So for a 2000 there were both C/K series and Silverados. To make things more confusing Silverado was a trim on the C/K series trucks. So it is possible you have a 2000 C or K series 2500HD with the Silverado...

  • Recommended Hitch for a 2001 Silverado 2500HD w/ a 12,000 lbs Capacity
    Not confusing at all. I took a look online and the 2001 Silverado 2500HD has a 12,000 lbs bumper pull towing capacity and a 15,200 lbs 5th wheel towing capacity. It's just two different capabilities of the truck. The extra weight of a 5th wheel trailer can be better supported when mounted more towards the center of your truck's frame. With the 12,000 lbs capacity in mind, I recommend the B&W Heavy-Duty Trailer Hitch Receiver item # BWHDRH25182. This is the only hitch available for...

  • Recommended Heavy Duty Hitch for a 2006 GMC Sierra Short Bed
    The Draw-Tite # DT45519 is designed to be used on the 8 foot bed models of the GMC Sierra and will not fit the short bed models. That being said, we do have Class V hitches with a 2 1/2 inch receiver options available for your short bed truck. The Draw-Tite # DT45517 is designed for short bed trucks and has a 13,000 pound towing capacity and 1,300 pound tongue weight capacity. This is upped to 17,000 pounds and 1,700 pounds, respectively, when a weight distribution system is used. The...

    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...

  • Recommended Class V Hitch for a 2002 Chevy Silverado 2500 HD w/ a 6 Foot Bed
    The best class V hitch for your 2002 Silverado 2500 is going to be the Curt Trailer Hitch item # C15703. This hitch is custom fit for the 2500 HD's with the 6-1/2' beds and bolts to your truck with included hardware. This hitch has a 2-1/2" receiver and is made in the USA. It has a 18,000 lbs towing capacity and a 2,700 lbs maximum tongue weight. This hitch can be used with weight distribution systems but they will not increase its 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.

  • Trailer Hitch for a 2006 Chevy Silverado 2500HD with Reading Utility Body
    Since you have that utility body the custom fit hitches for the 2006 Chevy Silverado 2500HD will not work. What you will need is a weld-on hitch. I have included a link to the options for you. A hitch like # 15902 creates a drop of 10.865 inches from the truck frame. Installation should be performed by a qualified professional welder.

  • Fit of Class V Trailer Hitch for 2002 GMC Sierra 2500 HD
    For a 2002 GMC Sierra 2500 HD, you'd want to use the Curt Class V hitch, part # C15703. I checked with Curt, and found that the drop of this hitch (measurement from the mounting flange to the top of the crossbar) is 5.13 inches, as shown in the photo I've provided. The # C15703 has a 2-1/2 by 2-1/2 receiver opening. According to Curt, their # C15323 Class V hitch you had asked about isn't a fit for the 2002 Sierra 2500 HD model, it's only a fit for the 1500 and the 2500 LD model. If...

  • Best Trailer Hitch for a 2008 GMC Sierra 2500
    The best trailer hitch for your 2008 GMC Sierra 2500 will vary depending on what you're going to use it for and possibly whether you have an 8 ft. or 6-1/2 ft. bed. If you need to haul a lot of weight I would suggest the Curt Class V CD 2-1/2" # C15703. This will get the most out of your truck for your dollar and will work with either length of truck beds. The Curt Class III # 13208 will also work with both bed lengths and would be more appropriate if you're not hauling as much weight. I...

    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,...

    By mounting hole dimensions I assume you are asking about the distance between them, and that distance is 39 inches for the Draw-Tite Trailer Hitch Receiver # DT45519. That is the same distance between the mounting holes as the similar hitch from Curt which also has a 2-1/2 inch receiver and fits a 2007 Chevy, the Curt Trailer Hitch Receiver # C15703. I have added links below to the installation instructions of both hitches for you to check out.

Several of these are TorkLift dual-receiver hitches that would almost surely NOT be compatible with your Tommy Gate so I have taken the requested measurement on the other three hitches from Curt and B&W. Note that Curt offers both 2-inch and 2-1/2-inch receivers for your truck. Part # C15302 is a 2-inch and part # C15703 is a 2-1/2-inch. The following...
