To replace your Leland 7921 pin box, we have the Reese Sidewinder Fifth Wheel King Pin with Rotating Turret by 5th Airborne, 16K # ST400-5AS16K which will move your king pin turning point back 22 inches to allow turning clearance. This will decrease vertical shock by up to 44 percent and longitudinal shock by nearly 60 percent.
