Upper Gearbox Mount Insert
PFF19-2230 Upper Gearbox Mount Insert is made from our Yellow 70A material and works by stiffening the OEM mount reducing the amount of engine/trans roll during hard acceleration and gear changing for a more responsive feel. An 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.
