Description

The Morryde Rubber Pin Box (MPN: RPB72-SEITZL18K-04) significantly improves fifth-wheel towing by absorbing road shock. Its patented rubber shear spring technology allows up to 3 inches of fore/aft and 1.5 inches of side-to-side movement, reducing chucking and jerking for smoother starts, stops, and overall ride. It's a maintenance-free design, fatigue-tested to CSA standards, and compatible with a wide range of trailer weight ratings.
