Upper Gearbox Mount Insert

PFF1-1130BLKLower EngineMountInsertis made in our hardestBlack 95Adurometer materialfor heavily tuned vehicles and track use for maximum strength and response. Designed to fillthe voiding in the OE rubbermount, it smooths out gear changes by stiffening and supporting the often perished rubber bush, which is common for failure on tuned vehicles. This will provide a more precise and settled transmissionresponse during acceleration anddeceleration.A small increase in NVH, usually at idle, should be expected whenstiffening the connecting mountbetween the engine/transmission and chassis.The harder the material used, the greater the NVH transmitted.
