We have three Sidewinder pivoting pin boxes that can replace your Lippert 1621HD model. All increase the truck/trailer pivot distance by 22-inches and all include a universal wedge to prevent the Sidewinder king pin from pivoting at the hitch so that it can pivot at the rear turret for more turning clearance. We do not have Sidewinders with more pivoting distance than this 22-inches.
We have Sidewinders in two weight ratings, 16K and 20K. Part # RP34FR is 20K, part # RP61422 is a 16K model with an internal air spring for a smoother ride.
These pin boxes can bolt on to replace several OEM pin boxes: Fabex and M&M models 663 and 665; and Lippert models 0719, 1621 and 1621HD.
