Sidewinder Options to Replace a Lippert 1621 Pin Box

Question

Question:

Im considering replacing my Lippert 1621 pin box with a side winder turret and pin box. I see so many part numbers offered what would be the correct numbers? Can you provide a list of Sidewinder numbers and fitments? Thanks

There are two options for Sidewinders to replace a Lippert 1621 pin box. For a 16k rated Sidewinder we have the part # RP61422. If you need more capacity than that you would want the 19k version which is part # RP34FR.

The first option listed above is an air-ride, cushioned Sidewinder that will offer a much smoother ride with its fully enclosed, custom-tuned air spring in air ride trailer coupler that cushions and absorbs shock.

To replace the 1621HD pin box on your trailer, the Reese Sidewinder # RP34FR will work perfectly. It has the capacity needed for this trailer size and will do a great job of providing all the turning clearance you need.

The Lippert pin box 1621 has a different design and bolt pattern so it requires a different turret than what is on #ST400-5AS16K. If the turret you have uses 4 bolts to mount to the arm, then you can just swap the turret for the right one, #RP61300.…

I do have an option for you but towing a 5th wheel trailer with a short bed truck using any sort of 5th wheel to gooseneck adapter is generally not a good idea because as you have come to find out they just don't provide the needed clearance. If…

The Lippert Road Armor Pin Box is cushioned which rules out being able to use any sort of fifth wheel to gooseneck adapter like the Convert-A-Ball Cushioned 5th-Wheel-to-Gooseneck Adapter part #CAB-C5G. The only option you'd have to change the…

The Andersen Ultimate Connection 5th Wheel Trailer Hitch System with Adapter - 20,000 lbs #AM3200 does give you a 9 inch offset but when talking with their tech he said that to use with RamBox the red coupler needs to be turned 180 degrees so it sits…

Answer 12

The safe GVWR rating is 80-85% of total weight capacity to allow for any additional weight added to the trailer. So for a 16k pin box you'd be looking at 12,800lbs - 13,600lbs as a safe weight. I looked up your current pin box with the LCI Number…
