If your 5th wheel jerks and chucks over uneven pavement, a rigid pin box is usually why — every bump transfers straight to the truck. MORryde's rubber pin box system replaces the Lippert 1621HD (built for 11.5K-14K GVWR trailers) with a design that isolates that motion instead of passing it along.
A patented rubber shear spring allows controlled fore-aft and side-to-side movement, smoothing out the ride without sacrificing towing stability. It's fatigue tested to CSA standards for long-term durability.
Confirm your existing pin box model and trailer GVWR before ordering to ensure correct fitment.
