Average Customer Rating:  4.8 out of 5 stars   (227 Customer Reviews)

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:
2005 GMCSierra

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:

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....

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:

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:

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:

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



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:

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



by:

Still an excellent product and still highly recommend it!

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



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:
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:

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:

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:
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:

Very heavy built, super easy to install



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:

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:

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



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 for 2007 Chevrolet Classic Silverado 3500
    For a 2007 Chevrolet Silverado CLASSIC, there is a "Select Vehicle Style" drop-down menu where you can select "3500 - Pickup" or "3500 Pickup w/ 10" DeepDrop bumper" If you have the DeepDrop bumper then you can use the B&W # BWHDRH25187 hitch with 2" receiver opening, and a tow rating of 16,000 pounds. If you need a wiring harness, and your truck has been pre-wired at the factory, you can use the Tekonsha # 118384 wiring adapter for 4-pole connector. If you have the standard bumper then...

  • 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...

    We offer Class V hitches in both 2-inch and 2-1/2-inch sizes for your 2009 Chevrolet Silverado 2500. All are shown on the linked page. Draw-Tite's 2-inch hitch # 41944 is a no-drill install since it bolts up to the bumper bracket the same way as the factory hitch. Written instructions and a helpful video are linked for you.

  • 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.

    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.

  • Using an In-Bed Camper while Towing an Enclosed Trailer with a Chevy Silverado 3500
    For your 2001 Chevy Silverado 3500, I highly recommend Torklift # TLC1205-30. The SuperHitch Magnum has more than enough weight capacity to tow your trailer with a hitch extension. For your hitch extension TorkLift # TLE1524 is the most solid option to carry your enclosed trailer. The SuperTruss needs to be used with # TLWD1000, which is a weight distribution system. Your trailer is too heavy for the the Curt hitch # C15703 paired with a normal hitch extension like # C45048 because you...

  • Is There a Curt 2-1/2 Inch Trailer Hitch that Fits a 2006 Chevy Silverado 2500HD 6-1/2 Foot Bed
    We do have a trailer hitch to fit your 2006 Cheverlot Silverado 2500HD but the Curt # C15800 is not a fit. It fits larger cab & chassis models. Instead hitch # C15703 is a 2-1/2 inch reveiver that fits. I've linked a video from when we installed it on a 2003 Silverado for you. If you also need trailer wiring I recommend # 30955 for your truck.

  • 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.

  • 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 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...

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.

These tie-downs are specific to a number of variables which you left out but assuming your '06 Silverado 2500 has an 8 foot bed and does not have any running boards you will need TorkLift Custom Frame-Mounted Camper Tie-Downs - Front # TLC2204 and the TorkLift Custom Frame-Mounted Camper Tie-Downs - Rear # TLR3501.

    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.

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...
