PFF16-721 Lower Engine Mount Insert is made in our Yellow 70A durometer material for increased mount longevity and performance. Designed to fill the voiding in the OE rubber mount, it smooths out gear changes by stiffening and supporting the often perished rubber bushing, which is common for failure on tuned vehicles. This will provide a more precise and settled transmission response during acceleration and deceleration. 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. PFF16-721 is also offered in our Black 95A durometer.
