Drivetrain movement and rear-end slack are common complaints on S14 and S15 Silvias, especially under hard launches or aggressive cornering. SuperPro’s Rear Differential Pinion Mount Bushing Kit with Tubes (part SPF2637K) replaces the soft factory rubber at the front differential mounting point with high-performance polyurethane bushings and new replacement tubes. This significantly reduces differential shift, tightens power delivery, and improves overall rear stability.
The complete kit includes everything needed for a strong, precise upgrade that enhances traction and minimizes unwanted noise while maintaining usable street manners. Perfect for street, track, or drift-built Silvias.
