5th Wheel Hitch for 2019 Ram 3500 With RamBox


Do you sell or how do I purchase a factory puck system to install on a 2019 Ram 3500 with Rambox?


Expert Reply:

The factory puck system is not an aftermarket option so there is no way to obtain one on your 2019 Ram 3500, and there isn't an underbed option, but you can still add a 5th wheel hitch to your truck. You will need above-bed rails to do so, and since you have the RamBoxes, a Sidewinder is required as well in order to obtain the needed clearance so the pin box does not hit the RamBoxes.

For a 5th wheel hitch you'll need one compatible with a Sidewinder, and for a hitch and base rails I recommend the Curt A-Series because of its premium dual jaw system which makes full contact with your king pin to give you a comfortable ride, and because its color-coded lock indicator makes the hitch easy to use. The custom install kit is also great for your truck because it doesn't require any drilling into your Ram's frame to install. The parts you need are the following:

- Curt A20 5th Wheel Trailer Hitch - 20,000 lbs # C16140
- Curt A25 5th Wheel Trailer Hitch - 25,000 lbs # C16180

- Curt Custom Fifth Wheel Installation Kit for Ram # C16430-204

To find the correct Sidewinder what you will need to know is the manufacturer and model number of the pin box on your fifth wheel and match that with the correct replacement, however, the correct part is likely the Sidewinder # RP34FR.

This will replace Lippert 0719, 1621 and 1621HD, Fabex 663 and 665, M&M 663 and 665, along with Lippert 1716, 1116, and 0115 pin boxes. The Lippert 1716, 1116, and 0115 pin boxes do require the Spacer Kit # RP97FR.

To use the Curt hitch with the Sidewinder you will need the Sidewinder Wedge Kit for Curt A-Series and E-Series Fifth Wheel Trailer Hitches # RP64FR.
