Rear upper control arm bushings are a common failure point on S13, S14, and S15 Silvia/180SX models, especially once the car is lowered or driven hard. SuperPro’s Standard Rear Control Arm Bushing Kit (part SPF1638K) replaces both inner and outer bushings with high-performance polyurethane that eliminates the flex and play found in worn factory rubber, resulting in tighter rear geometry, improved stability, and more predictable handling.
This is a direct, non-adjustable replacement kit designed for standard geometry setups (toe adjustment remains available via the front wheel steering method). It delivers noticeably sharper rear response and better traction while maintaining a balanced ride quality suitable for street and spirited driving.
