Gearbox Mount Front Bush Insert

Fits European models only. This insert is made in our Purple 80A durometer material for increased transmission mount longevity and performance on tuned engines. Designed to fill the voiding in the OE rubber mount, it smooths out gear changes and throttle application by stiffening and supporting the often perished rubber, a common failure on tuned vehicles. A small increase in NVH, usually at idle, should be expected when stiffening the connecting mount between the engine/transmission and chassis. The harder the material used, the greater the NVH transmitted.
