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.

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:

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.

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.



by:

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.

NOT PACKAGED WELL. IT WAS MISSING AND DIRECTION/PAPERWORK AND THE HARDWARE WAS NOT INCLUDED.

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:

fit good and was promptly delivered.



by:

i think it needs side plates also



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:

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:

Great product



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.



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:

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.

  • Class V Trailer Hitch for a 2011 Dodge Ram 2500 with OEM Trailer Hitch
    Curt trailer hitch # C15800 is designed to fit cab and chassis models. Cab and chassis models have a more narrow frame width compared to regular pickups. If you do not have a cab and chassis model this hitch will not fit. For a regular pickup version of the 2011 Ram 2500 with the OEM hitch you can install Curt hitch # C15809. It will fit beneath the factory hitch. I have included links to the instructions and an installation video for you to view. I also recommend etrailer ball mount...

    If your 2019 Ram 3500 is a pick-up truck the Curt Class V Receiver Hitch part # C15800 is not a fit because it fits the cab and chassis model of the Ram 3500 which have a 34" wide frame. If your truck is a cab and chassis with 34" wide frame the Curt receiver is a great choice. I have attached a video of the hitch installed on a cab and chassis for your reference. It sounds like your truck is a 2019 Ram 3500 pick up. If it is a short bed model with a 6-1/2 ft bed, I recommend Curt Trailer...

  • How Does a Curt Trailer Hitch Install on a 2012 Dodge Ram 4500 Cab and Chassis
    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...

  • 2024 Ram 5500 Cab and Chassis 2-1/2" Trailer Hitch Receiver Options
    We have 2 different 2-1/2" hitch receiver options for your 2024 Ram 5500 Cab and Chassis and the correct one just depends on what you're looking to get out of the hitch. The Curt # C15800 is your classic hitch receiver while the TorkLift # TL49YR is a dual stacked receiver that gives you both a 2" and a 2-1/2" receiver. I recommend going with the Curt unless you're going to be towing a trailer and needing to carry a bike rack, or use an in-bed camper and need a special hitch extender...

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.

  • Trailer Hitch Recommendation for 2008 Chevy Silverado with Service Body
    We have a solution, but the utility body trucks do not have custom hitches made for them. There are only multi-fit hitches that will fit that type of vehicle. I spoke to my contacts at Curt and Reese and the only styles of hitches that can be made to fit a service body truck like yours are multi-fit RV hitches like the # 41990 that has a 16k capacity. This is a weld on hitch that would require either the 7 inch drop brackets part # 4907 or the 16 inch brackets part # 4916.

  • Universal Weld-On 2-1/2 Inch Trailer Hitch Receiver For 34 Inch Truck Frame

So it will fit those trucks but otherwise I can't guarantee any fit. What you can use though, is a universal weld-on option, which will fit your 34 inch wide frame: - Curt Class 5 Universal Weld-on Hitch with Brackets - 2-1/2"...
