Product Description

The SuperPro SPF4888K Rear Differential Pinion Mount Lower Bushing Kit is designed to replace the OEM forward differential mount bushings, commonly known as pinion mount bushings. Over time, factory rubber bushings can degrade, leading to increased differential movement, reduced throttle response, and unwanted noise and vibration.

Constructed from durable polyurethane, these bushings offer enhanced longevity and performance. They effectively reduce differential movement under load, improving driveline stability during acceleration and deceleration, all while maintaining OEM levels of noise, vibration, and harshness (NVH). This direct replacement kit requires no modifications and reuses existing OEM hardware.

Ideal for both street and performance applications, the SuperPro SPF4888K kit ensures your vehicle's differential remains securely mounted, providing consistent performance and a more responsive driving experience.
