Great product, great quality, comes with all mounting hardware. Free shipping and was delivered just two days after ordering. Only complaint is that it’s advertised to only have to drill out the rivets in the back of the frame but on my truck (2022 ram 4500) you have to drill every hole. Also says you need a 25/32” drill bit which to me is too big, I used a 5/8” and the hole is the perfect sizeOther than that it was easy to install as long as you have the right tools. I order all my hitches and related products from etrailer and will continue to do so.

@Braxton The # C15800 will fit your 2008 Ram 3500 if it's a cab/chassis model. If it's a pickup model, use # C15809.

2009 Chevrolet Silverado

The hitch was good. The holes didn't all line up. The directions called for 19/32 drill bit that was too small for the bolts supplied. It was a 5/8ths bolt and so i needed the same size drill bit. The box was beat up and the hitch busted through the box. The hitch had scratches that broke through the paint. Send some padding in the future.

It sounds like the side brackets could have been flexed out of alignment since the hitch had also broken through the box. We do have a FAQ that can help with that. I will also have Customer Service reach out to you about the scratches that the hitch received.



by:

We replaced our original RV hitch with this one because the original one bent due to pressure from our spare tire holder. This hitch is very heavy duty and has been working well for nearly a year. Highly recommended!



by:
Dodge Ram Pickup

2016 Dodge Ram Chassis Cab, 9' bed, 34" frame rails.

Extremely beefy trailer hitch. Easy to install, especially with no bed on the truck. The two rear rivets on the Ram frame rail are time consuming to drill out. Clears the rear 52 gallon fuel tank with no problems. It should be noted that the holes where the safety chains would hook are very beefy as well so small chain hooks will not work. Shackles will solve that proble and be more secure at the same time. I'm very happy with my purchas of this hitch and etrailer.com did a great job helping me find the correct hitch and shipping it out fast.

This is and always has been a superior product for my use. This hitch is ultimately the best choice to put on our Semi Trucks. It gives me the ability to haul more freight. Now I can haul any reciever hitch or pintle hook load along with my standard 5th wheel loads.
Being in the Power Only industry versatility is key to our business... Outstanding Product

Came earlier than expected. Fit my 01 gmc 3500 cab and chassis great. Easy install. Found it cheaper here than anywhere else. etrailer is always the first place I look when I need just bout anything for my truck or rv.

Very well built, heavy, didn't fall off. Would tow again



by:
2006 Chevrolet Silverado

This trailer hitch is very well built.
Always
concerned when pulling a heavy load down the highway. This hitch is rated for as much weight as my one ton truck is. I have no doubt this hitch will last as long as the truck



by:

Just received the hitch. Looks heavy duty. etrailer was fast, friendly, and very helpful. Big thumbs up! Can’t wait to install it this weekend.



by:

The product is excellent
The instructions
say a professional can install in 30 minutes which is impossible because it will take an hour, or more, just to drill holes



by:
Dodge Ram Pickup

I purchased this hitch for my 2022 Ram 5500. The hitch arrived lightning fast and installation was very simple. The hitch arrived with all the necessary Grade 8 bolts and the entire installation took less than 30 minutes. I did have to drill two holes but that was no issue and it was probably due to the fact that I have a cab and chassis model. The hitch is nice and square and tows well. After a trip from Texas to Washington state all the hitch bolts are still tight and the hitch is still nice and square and the finish looks resilient.

It looks like we missed the boat on this one. I will have our customer service department reach out to you to get this corrected.



by:

Delivery was very fast. Just wanted everyone to know drilling is required. Or I guess you could have it welded on. Not my choice in case of damage to hitch.



by:

fit good and was promptly delivered.



by:

i think it needs side plates also



by:

took longer to install than what it said , but that's typically the case. It was a relatively smooth install. I just takes a minute to drill through frame metal.



by:
2015 Chevrolet Silverado 3500

Hitch was installed on a 2015 Chevrolet 3500 with dual fuel tanks.
This hitch fit behind the fuel tank skid plate mounting bolts without relocating the skid plate mounts. The middle bolt lined up over the crossmember requiring a factory rivet to be drilled out, but the hitch is then mounted to two layers of frame
The hitch itself is very well made, the bolt flange is true to the truck frame, good mounting hardware included. it has a flat bedliner type finish on it.



by:

Very sturdy, good welds, easy install with no mods required.



by:

It was a perfect fit for my M35A2 could not ask for anything better will recommend to all my friends



by:

Fitment of the hitch was as advertised. Shipping was quick (A day earlier than expected). So far we have ordered multiple hitches and axle parts from e trailer and never been disappointed with any of them. Keep up the good work guys. You are our go to trailer and hitch company.

Great product



by:

etrailer had the best price for this hitch everywhere else was over $300 before shipping I got the hitch and 3day shipping for $xx.xx and some change.. install was easy but drilling the frame is pain in the butt just because of how solid the metal is.. the instructional video explained everything I needed to know and made the install a breeze.. instructions do come with the hitch however I only referred to them for torque specs.. if you’re mechanically inclined you and a buddy can have this installed in no time.. THIS HITCH WILL WORK WITH A SERVICE BODY THAT HAS A REGULAR J-MODEL BUMPER WITH LITTLE TO NO ISSUE.. I replaced a jerry-rigged POS hitch some “fabricator” made that ultimately almost destroyed the bumper and could’ve killed someone



by:

This was the most heavy duty receiver hitch I could find. It was a reasonable price and it was a simple installation. The finish has held up well after a year on the truck, with a bunch of off highway miles. It was a good value and does a great job for those heavy loads.



by:

The receiver hitch is heavy duty and looks to be well built. It fit perfect on my truck, the only tough part about it was working around the flatbed that I already have on the vehicle. So from my personal experience if you don't already have a bed on your truck, put the hitch on prior to putting the bed. It would make the install process much easier. Overall a great product and I would recommend to anyone in the market.

  • 2-1/2 Inch Trailer Hitch Receiver Fit on 2021 Ram 500 Cab & Chassis
    Thank you for the photo, and while there is a 2-1/2 inch trailer hitch receiver that fits your 2021 Ram 5500 cab & chassis, I checked with the manufacturer, and the TorkLift hitch you mentioned will not fit. So for a 2-1/2 inch hitch, you will need to go with a Curt hitch: - Curt Trailer Hitch Receiver # C15800 This is a Class V hitch that has a massive 2,700 lbs tongue weight capacity and 20,000 lbs towing capacity.

    I do have some solutions for your 1970 Ford F-250, however, the Curt Trailer Hitch Receiver # C15800 you reference is not a fit for your truck. If your vehicle has the deepdrop style bumper, then I recommend the Curt 3-Piece Trailer Hitch Receiver # C15511. This is also a class V hitch like # C15800, and is rated for 15,000 maximum GTW and a maximum of 1,500 tongue weight.

  • Difference Between 2-1/2 Inch Curt Trailer Hitch C96CR & C15800 For 2021 Chevy Silverado 3500
    Good question, and the difference is what they fit; the Curt Trailer Hitch Receiver # C15800 is designed to fit cab and chassis frames of not only a Chevy, but also Ram trucks. Cab and chassis frames are much narrower than pickup frames, which is why they are different fits. So if your Silverado 3500 is a cab and chassis, you can use the Curt Trailer Hitch Receiver # C15800. Otherwise, if your '21 Chevy Silverado 3500 is a standard pickup, the correct fit for a 2-1/2 inch hitch is the...

    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.

  • 2007 Dodge Ram 3500 Class V Hitch Options from Curt
    The Curt hitch part # C15800 does fit a 2007 Dodge Ram 3500 but only if the vehicle was a Cab and Chassis model which means it was sold without a truck cab and the frame dimensions are 34 inches apart measured from outside to outside. For a similar Class V hitch for a non-cab and chassis style truck you'd want the part # C15409 which fits if the truck came with a factory hitch or did not come with one. This hitch has capacities of 17,000 lb total trailer weight.

    In order to install Curt trailer hitch # C15800 on your 2012 Dodge Ram 4500 cab and chassis model you will have to drill into the frame because, like you have said, there are no holes in the frame already. The rivet that is in the rear most part of the frame also will come out and get replaced by a bolt. Installation is very similar to hitch # C15400 (just the capacities are different) and I have linked the instructions for it for you to view. The hitches install with 3 bolts on each...
