On S13, S14, and S15 Silvia/180SX models, the differential-to-crossmember mounts are a frequent source of flex and drivetrain movement, especially once the car is lowered or making serious power. SuperPro’s Differential To Crossmember To Chassis Mount Bushing Kit (part SPF3775K) replaces the soft factory rubber with high-performance polyurethane shell bushings that stiffen this critical connection, reducing slack, minimizing wheel hop, and delivering more immediate power to the rear wheels.
This targeted upgrade sharpens rear-end response and improves overall chassis composure for both street and drift applications while maintaining acceptable ride quality.
