Features to know about

Haul More Without Worry: Heavy-Duty Class V Strength

When you’re towing serious weight, you want a hitch that won’t flinch. This Curt Class V Commercial Duty hitch is rated for a maximum 20,000 lbs gross trailer weight and 2,700 lbs tongue weight, even when used with weight distribution. The 2-1/2" x 2-1/2" receiver opening gives you the flexibility to run large ball mounts and heavy-duty towing accessories. Its precision, robotic welding maximizes strength where it counts, so you can tow trailers, small equipment, or campers with confidence.

Skip the Welding: Bolt-On Installation Made Simple

Installing a hitch doesn’t have to be complicated. This one bolts directly onto the frame with a complete hardware kit—no welding required. The mounting points are designed for a custom fit that lines up flush and true. Whether you’re installing in the driveway or in a shop, the fitment saves time and cuts down on frustration.

Built to Outlast the Job: Corrosion-Resistant Steel Construction

Every detail here is about durability. The fully welded steel design is coated in a black powder finish layered over a protective base coat for superior rust resistance. The square-tube construction keeps it rigid under load and looking clean under the bumper. It’s built to handle tough conditions season after season while keeping that solid, “ready-for-anything” look.

Ready for Real-World Use: Works with Ball Mounts and Accessories

You can hook up what you need without compromise. The 2-1/2" receiver is made for hauling heavy trailers but also pairs well with larger cargo carriers or heavy-duty bike racks when you need extra utility. Ball mount, pin, and clip are sold separately, so you can choose exactly what setup works best for your towing style.

Exactly what I needed to feel more comfortable towing heavy loads!

The technician that I spoke with was very helpful in selecting the right hitch for what I needed and the product was very easy to install.

This hitch fit perfectly with my Ranch Hand Legend bumper - on a 2016 Ram 3500 dually. Easier to install than I had thought too!



by:

Great fit and love it. Bolted right into place!



by:

The customer service has been great and proactive. While I have not installed the hitch yet the service and shipping was very good. I plan to use the hitch to mate with a factory installed receiver to provide for an extended hitch to pull a horse trailer with a truck camper. Customer service directed me to a much more economical option than the one I was considering. I expect I will need to do a little remanufacturing on my extension to make it all work but for the savings etrailer provided with the alternative hitch I can do a lot of remanufacturing.

The Hitch worked as represented. It was easy to install and fit the truck as it should. I am very happy with the end result.



by:

This hitch works great! Since it sits a bit lower than the factory hitch, It allowed me to put a heavier Ranch Hand bumper on the back without losing the ability to tow heavy trailers.

  • Recommended Class V Hitch for a 2017 Ram 3500
    Hey George! We do have a class V hitch that will fit your 2017 Ram 3500 dually. It is the Curt item # C15803. This class V hitch is custom fit and bolts to your Ram with included hardware. It is compatible with both bed lengths and the dually model. It will not fit a cab and chassis model only a standard pickup truck. Please note the Curt Hitch item # C15800 you were looking at will only fit the cab and chassis models of the 2017 Ram 3500. Is your Ram 3500 a standard truck or the cab...

  • Will Curt Class V Hitch Fit 2024 Freightliner S2RV
    Hey Tom! The Curt # C15803 is designed to fit certain Ram trucks. Some people might have modified the hitch or just welded it on to get it to fit their Freightliner S2RV but it won't be able to just bolt on. If you're going to go that route you're better off using the Curt Class 5 Universal Weld-on Hitch w/ Brackets # C99CR (2" receiver) or # C87CR (2-1/2" receiver). This fits frames up to 44" wide and the brackets can be cut down or modified as needed for proper fitment. What will...

  • Recommended Hitch for a 2018 Ram 3500 Cab and Chassis
    I would be happy to! It sounds like your 2018 Ram 3500 is the cab and chassis model. To add a hitch to it you will want the Curt Trailer Hitch Receiver item # C15800 for a 2-1/2" receiver or item # C15400 for a 2" receiver. Both of these hitches are custom fit for the cab and chassis model Ram 3500's and bolt to it with included hardware. These both fit single rear wheel and dually trucks that have a frame width of 34" wide measured from the outside of the frame rails. I have linked a...

  • Determining Ground Clearance on 2014 Ram 3500 with Curt Class V Hitch # C15803 Installed
    The Curt Class V Trailer Hitch Receiver # C15803 referenced in your question is confirmed to fit your 2014 Ram 3500 and will sit directly beneath the factory hitch receiver on the truck. We have not gotten a chance to install this hitch on the 2014 Ram so we don't have any pictures, but I do have a measurement on the hitch that will allow you to see how far the new receiver will hang down below the truck. From the top of the mounting brackets on the hitch to the bottom of the receiver,...

  • Recommended Class V Hitch for 1975 International HD200
    The Curt # C15803 you referenced is only a fit for 2014-2018 Ram trucks so that isn't the correct fit. Because you have a 34 inch frame, I recommend the Buyers Products Class 5 Service Body Hitch Receiver - 2-1/2" # 3373018538 which measures end to end 44 inches but then you will weld brackets at your required fit. For that hitch with 9 inch brackets, I recommend # 3371801052. If you want to use a smaller hitch, there is a bolt on option in the Curt Trailer Hitch Receiver - Custom...

  • What is the Highest Rated Hitch You Carry for a 2017 Dodge Ram 3500 Dually?
    I have an answer about trailer hitches for your 2017 Dodge Ram 3500 dually. Unfortunately, we do not carry a hitch rated for a 30,000 pound towing capacity. The highest hitch we carry for your truck is the Curt Trailer Hitch Receiver - Class V Commercial Duty - 2-1/2" # C15803. This hitch comes with a maximum gross towing capacity of 20,000 pounds and fits both 6-1/2 foot and 8-foot bed models.

  • TorkLift Hitch and Camper Tie Downs for 2018 Ram 3500 Crew with Factory Hitch/Running Boards
    For a 2018 Ram 3500 Crew Cab with factory hitch and 8-foot bed we do have hitch fits that are shown on the linked page. These include both 2-inch hitches like Draw-Tite # 41929 which fits with a standard factory bumper and 2-1/2-inch hitches like TorkLift # TLD1108-30. This is pre-drilled for TorkLift camper tie downs. The fit of camper tie-downs depends on several factors including your hitch. TorkLift offers both steel and aluminum camper tie downs for the Ram 3500 Crew Cab 8-foot bed...

  • Why Does Curt Hitch C15803 Not a Confirmed Fit with Aftermarket Bumper
    Aftermarket bumpers are different sizes and shapes compared to the factory bumpers so the hitches we offer like the part # C15803 are designed to fit and clear the factory bumpers but since the aftermarket bumpers are a different size there's not easy way to tell if the hitch would also fit with it and not interfere.

  • Replacing Factory Trailer Hitch on a 2016 Ram 3500
    Your best option is going to be Draw-Tite hitch # DT45509. This hitch requires removal of the factory hitch on your 2016 Ram 3500. It is rated for 2,000 pounds tongue weight and 18,000 pounds gross trailer weight. When used with weight distribution it is rated for 2,500 pounds tongue weight and 18,000 pounds gross trailer weight. The available Curt hitches will all sit low whether you remove the factory hitch or not. The Draw-Tite hitch will be tucked up beneath the bumper like the factory...

  • Trailer Hitch to Fit with Factory Hitch on 2017 Ram 3500
    The Draw-Tite Ultra Frame Trailer Hitch # 41952 is a confirmed fit for the 2017 Ram 3500 Cab and Chassis models, but not the actual pickup truck version of this vehicle. If you have the pickup version of the Ram 3500 with the factory hitch you'll want to use the Curt # C15803 (fits both 6-1/2 ft and 8 ft truck beds) which will sit under your existing factory hitch and does not require any modifications like removing the cross member, as long as you have the factory bumper; this hitch...

  • Recommended Towing Trailer Hitch Extender For 2017 Ram 3500 Short Bed With Truck Bed Camper
    If you have a 2-1/2 inch hitch receiver on your 2017 Ram 3500, I recommend the Curt Hitch Extension and Reducer for 2-1/2" Trailer Hitches - 24" to 34" Long # C45048. This would be limited to 4,500 lbs without weight distribution or 6000 lbs with weight distribution. If you don't have a factory receiver, then you will need the Curt Trailer Hitch Receiver - Custom Fit - Class V Commercial Duty - 2-1/2" # C15803 to use that extension.

  • Curt Trailer Hitch Receiver C15803 Fitment for Factory Bumper
    The Curt Trailer Hitch Receiver # C15803 will bolt to the frame with the included hardware and if you have the OEM Hitch it will also bolt to part of that hitch. It does not connect to the bumper but rather will not fit on vehicles that have aftermarket bumpers installed. That is the reason you see "Requires factory bumper for installation" under the Installation Notes.

  • Recommended Class V Trailer Hitch for my 2014 Ram 3500
    We have a great solution but the Curt Trailer Hitch Receiver part # C15845 is not a confirmed fit for your 2014 Ram 3500. Instead the Curt Trailer Hitch Receiver part # C15803 is the one to go with. It share the exact same specifications as the one you looked at but is custom designed for your truck with or without a factory hitch.

  • TorkLift Rear Camper Tie Downs for 2014 Ram 3500 with 8 Foot Bed
    The rear TorkLift tie-downs for your 2014 Ram 3500 with an 8-ft bed and no rear step under the truck bed and non-TorkLift aftermarket hitch are the # TLR3500. These are a powder coated steel construction so they'll be resistant to corrosion and durable. If you also need the front tie downs you'll want to use the # TLD2124 which are the matching pair for the # TLR3500. Because the Curt # C15803 is not pre-drilled for TorkLift tie downs, you may need to drill into the hitch side plates,...
