PowerFlex MINI R55/R56/R57/R58/R59/R60/R61 Upper Engine Mount Insert

PFF5-224 provides an excellent balance of strength and compliance for improved performance, while limiting NVH transmission into the cabin. Available in 3 material variants, you can choose the insert that best suits your driving and vehicle requirements.

PFF5-224 Upper Engine Mount Insert (Gas/Diesel) is made from our Yellow 70A durometer material, providing an excellent balance of strength and compliance for improved performance, while limiting NVH transmission into the cabin. This part is recommended for Gas models and high-torque tuned Diesel models.

PFF5-424R Upper Engine Mount Insert (Diesel) is made from our softest Red 65A material, specifically designed to minimize NVH transmission. Recommended for unmodified Diesel models or for drivers who want a subtle improvement in driving feel without compromising comfort.

PFF5-424BLK Upper Engine Mount Insert is made from our stiffest 95A Black Series material, providing a no-compromise performance option for track-focused builds. 

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.
