Made in our Dark Grey 80A durometer material to give the appearance of rubber but with the performance and longevity of polyurethane, reducing bush deflection by an impressive 50%. A small increase in NVH, usually at idle, should be expected when stiffening the connecting mount between the transmission and chassis. The harder the material used, the greater the NVH transmitted.
