Which Offset Gooseneck Hitch Ball Will Fit the Factory Prep/Puck Hitch In My 2021 Ram 3500 Dually?


I have a 2021 Ram 3500 maga cab Dually. Will the curt 4” offset ball work for this truck with factory installed hide a ball.

To use a offset gooseneck ball on your 2021 Ram 3500 you will need to replace the factory gooseneck hitch with a B&W Turnoverball Underbed Gooseneck Trailer Hitch # BWGNRK1320. The B&W hitch mounts in the same place as the factory hitch, and does not affect the outer 4 mounting holes for a 5th wheel hitch. This will allow for you to use their 4" Offset Ball # BWGNXA4085. You can use the Reese Safety Chain Holder # RP30145 in the factory puck holes if you do not want to drill for the safety chain mounts included with the B&W hitch.

The Curt 4" Offset Ball # C602 will only work with their double lock connection. The factory hitch does not utilize a pin that inserts into the ball so the Pop-In Ball # C60601 they use is free to turn inside the hitch.
