Rear Control Arm Bushing

This system targets the inherent weaknesses in the stock rear control arm bushing, which often deflects laterally and fore/aft under load. This deflection leads to imprecise steering, dynamic toe changes during braking and cornering, and can contribute to excessive inner tire wear, a known issue on many Lexus models. The USRS kit features a redesigned 6061-T6 lower control arm housing, built to be stronger than OEM to handle increased thrust loads. It incorporates an extremely tough 88 durometer polyurethane bushing, backed by a lifetime guarantee. This bushing is designed with a fully fluted configuration for enhanced lubrication and an end seal to prevent dirt ingress. By virtually eliminating unwanted suspension movement that causes changes in toe, caster, and camber, the USRS dramatically improves steering response and feel during hard cornering without the harshness associated with race-only spherical bearings. The redesigned housing also increases static caster by 0.3-0.5 degrees, further improving steering feel and camber gain. This product comes as a complete, pre-assembled bushing and housing unit, simplifying installation and eliminating the need for costly labor to press out old OEM bushings. All components are engineered and manufactured in the United States of America.
