SuperPro S14 S15 Rear Differential Pinion Mount Bushing Kit (Without Tubes) For Nissan Silvia

Rear differential movement is a common issue on S14 and S15 Silvias, especially when modified or driven hard. The factory pinion mount bushings compress and allow excessive shift, resulting in lost traction, drivetrain slack, and annoying noises. SuperPro’s Rear Differential Pinion Mount Bushing Kit Without Tubes (part SPF2582K) replaces the soft rubber at the front mounting point with high-performance polyurethane bushings while reusing your original inner tube for a precise, cost-effective upgrade.

This focused kit tightens the rear end, improves power delivery to the ground, and enhances overall stability for both street and drift use. It delivers a noticeable improvement in responsiveness without making the car overly harsh for daily driving.
