The Roto-Joint design improves performance over the factory rubberand aftermarket polyurethane bushings by allowing the suspension to articulatecorrectly, and provide precision handling. The installed UMI Roto-Joint allowsrear end free movement when high handling, auto cross or road race is a concernwhile still being a 100% streetable setup. The installed delrin race, whichlines the spherical ball, absorbs shock and road noise for a quiet and smoothoperation on any street or track driven vehicle.

Thepolyurethane bushing end is designed to be bolted to the vehicle chassis sidewhile the Roto-Joint attaches to the rear end side.
