Prothane 8-703 Polyurethane Steering Rack and Pinion Bushing Kit

The Prothane 8-703 is a premium polyurethane steering rack and pinion bushing kit engineered to replace worn factory rubber bushings with a longer-lasting, higher-performance alternative. Designed as a direct factory replacement, these bushings restore proper rack positioning and deliver noticeably improved steering precision and chassis feedback.

Why Upgrade to Polyurethane?

Factory rubber rack bushings deteriorate over time, allowing excessive rack movement that translates into vague, imprecise steering feel. Prothane's precision-molded polyurethane construction resists compression, chemical contamination, and physical wear far better than OEM rubber, helping maintain consistent rack alignment and a more connected, responsive steering experience.
