Custom Performance Engineering is very proud to release the xFlex™ EPDM (ethylene propylene diene monomer) rubber pitch stop mount for many Subaru vehicles! CNC machined from a single piece of billet 6061-series aluminum; this mount is not only totally indestructible, but it also transmits far less NVH (noise, vibration and harshness) into the cabin than comparable mounts.
Our Subaru xFlex™ Pitch Stop Mount is unique compared to our competitors mounts both in form and in function. cp-e™ goes a step further than the competition by using EPDM, a sort of rubber, bushing. Urethane begins to fail at temperatures as low as 200°F and generally the bushings need a higher durometer rating to hold together. The location of the mount allows a large amount of heat to be transferred to the bushing. EPDM holds up to this heat and doesn’t begin to break down and fail. EPDM has a higher density than urethane, so the bushing can have a lower durometer rating while keeping high reliability and support. Why is that good? Higher durometer ratings transfer vibrations through the vehicle and into the cabin, raising the NVH (noise, vibration, & harshness) value. Available in 70A durometer option!
