2019-2024 Ram 6.7L Cummins 5th Wheel Hitches

Fifth-wheel hitches on the 2019-2024 RAM 6.7L Cummins

The 2019 redesign gave the frame a fully boxed rear section and an upgraded rear-axle crossmember with fifth-wheel and gooseneck provisions. Trucks built with the factory 5th-Wheel/Gooseneck Towing Prep Group have four pucks in the bed floor and a 7-pin plug inside the bed. For 2021, Ram upgraded the rear crossmember again and integrated the pucks, gooseneck plates and center casting into the box floor. At the top of the range, a 2019 3500 with the Max Tow package came with a 30K fifth-wheel hitch already installed, along with 4.10 gears, dual rear wheels, auto-leveling rear air and a trailer brake controller.

Before you hook up

Two recalls on 2019-2022 trucks involve the bed and tailgate you work around every time you hook up a fifth wheel. Recall 20V-207 covered an accessory bed step that could fail, and 22V-904 covered tailgate strikers that could let the tailgate open. Neither one is a hitch defect, but you rely on both when you climb in to check the hitch and drop the tailgate to back under the trailer. If you bought the truck used, have the recall status checked by VIN.

Factory hitch vs. aftermarket puck hitch

If your truck has the prep group but no hitch, or you want something other than the factory 30K, a Ram-specific puck hitch drops straight into the factory pucks. Whatever brand you choose, it has to be the Ram-pattern version; a Ford or GM puck hitch will not fit. If the truck has no pucks at all, Mopar prep kits add them to trucks built without the prep group, and then a Ram puck hitch drops in the same way.

What we carry

The B&W Trailer Hitches Companion RVK3670 is the Ram OEM-puck version of B&W's fifth-wheel hitch, listed for 2010-2025 Cummins Rams. Next to it is Lucas Oil 10030 5th Wheel and Slider Lube for the hitch and slider. More towing hardware is in our hitches section.

Fitment notes

Before you order a puck-mount hitch, confirm the truck actually has the factory prep: four pucks in the bed and an in-bed 7-pin. Check the model years on the hitch listing against your truck, since Ram changed the bed floor for 2021. Your towing capacity depends on the whole truck, not just the hitch, so look up the numbers for your cab, axle, rear wheels and engine output. Verify by VIN, or call and we'll do it with you. For everything else on this engine, start at the Cummins hub.

Frequently asked questions

Can I move my fifth-wheel hitch over from a Ford or GM?

Not as a puck-mount hitch. Ram uses its own puck pattern, so a hitch built for Ford or GM pucks will not drop into a Ram bed. You need the Ram version, such as the B&W Companion RVK3670 listed here.

My truck has no pucks in the bed. Can I still run a puck hitch?

Yes, once the pucks are in. Mopar prep kits add the pucks to trucks built without the factory prep group. After that, a Ram-pattern puck hitch drops in the same way it would on a factory-prepped truck.

How heavy a fifth wheel can my truck pull?

The 2019 top rating was 35,100 lb, and it took a 3500 regular cab 4x2 dually with the high-output engine and 4.10 gears, with a 43,000-lb GCWR. A Cummins 2500 in Ram's 2019 chart is rated 15,520 to 19,780 lb. Use your exact build's numbers, and remember that pin weight counts against payload.
