Prothane Polyurethane Steering Rack Bushing Kit
For 1984–1989 Toyota MR2 & 1983–1987 Toyota Corolla AE86 Trueno & Levin SR5, GTS and All JDM Trims equipped with Manual Steering
Overview
Restore crisp steering response and eliminate excessive steering rack movement with the Prothane Polyurethane Steering Rack Bushing Kit. Designed as a direct replacement for worn factory rubber bushings, this kit securely mounts the steering rack to the chassis, reducing unwanted flex while improving steering precision and driver feedback.
Manufactured in the USA from premium Prothane polyurethane, these bushings are engineered to outlast conventional rubber. They resist oil, grease, road salt, chemicals, moisture, ozone, and UV exposure while maintaining their shape under demanding street, autocross, drift, and track conditions. Compared to aging OEM rubber bushings, polyurethane provides firmer steering feel, greater durability, and more consistent handling performance.
Designed for manual steering, rear-wheel-drive Toyota applications, this kit provides an excellent upgrade for restorations and performance builds alike.

Why Upgrade to Polyurethane?
Factory rubber steering rack bushings soften and deteriorate with age, allowing unwanted steering rack movement that can reduce steering precision. Polyurethane bushings maintain their shape under load, resist deterioration, and provide a firmer steering feel for improved confidence on the street or track.
