For a Lippert 1621 pin box replacement you can use the 5th Airborne Premium 5th Wheel Air Ride King Pin w/ Sidewinder and Turret # RP61422. This bolts right on to your trailer using your existing hardware and it will cushion your ride with its adjustable air spring and shock absorber. The rotating turret will provide a new pivot point 22" behind the king pin.
The Reese 5th Airborne Premium Fifth Wheel Air-Ride Pin Box w/ Sidewinder and Turret # ST400-5AS16K is instead a direct fit to replace Leland pin boxes 7910, 7920 and 7921, and Dexter model 221-0037, but it does not fit in place of a Lippert 1621.
