Product Details

ISR Performance Solid Differential Mount Bushings for the 1999-2002 Nissan Silvia (S15) are built to eliminate OEM rubber flex at the differential mount, kill wheel hop, and translate more of your torque into forward drive. If you've lowered the Silvia on coilovers or dropped springs, factory hardware in this location can no longer keep the alignment honest — these parts solve that problem and sharpen how the chassis feels under load.

Every ISR solid differential mount bushings set uses CNC-machined billet construction with performance-grade spherical bearings or poly bushings where appropriate. Bolt them in using OEM mounting points — no welding, no cutting — and get the S15 Silvia back into alignment spec with the adjustment range daily-driven, canyon-carved, and track-day Silvia owners actually need.

Features

  • Solid aluminum or urethane construction eliminates OE rubber flex
