PFF5-4628P Transmission Case Bushing Insert (Standard) is made from our Yellow 70A durometer material, providing an excellent balance of strength and compliance for improved performance on standard Petrol/Diesel vehicles whilst limiting NVH transmission into the cabin. An increase in NVH, usually at idle, should be expected when stiffening the mount between the transmission and chassis. Also, PFF5-4628P is offered in our Performance 80A durometer and Black series 95A durometer. The harder the material, the greater the NVH transmitted.
