The SuperPro SPF3879K Front Gearbox Mount Insert Bushing is an essential upgrade for drivers looking to sharpen drivetrain response and improve shifting precision. By filling the voids in the factory gearbox mount, this insert significantly reduces transmission movement and lash during aggressive acceleration and gear changes. This provides a more direct, connected feel through the shifter without the excessive noise, vibration, and harshness (NVH) typically found with solid aftermarket mounts.

Engineered and manufactured in Australia, these inserts are crafted from SuperPro's proprietary engineering-grade polyurethane. Unlike standard rubber, this material is specifically formulated to withstand extreme temperatures and resist degradation from oils, water, and coolant. This ensures the bushing maintains its integrity and alignment under harsh performance driving conditions.
