cp-e™ xFlex Stage 1 Rear Motor Mount for 2013+ Ford Focus ST

cp-e™ xFlex Stage 1 Rear Motor Mount for 2013+ Ford Focus ST

$ 144.39

[From the manufacturer...]

Custom Performance Engineering is very proud to release the first aftermarket EPDM (ethylene propylenediene monomer) rubber engine mount for the Focus ST! 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.

Focus ST Rear Motor Mount

Our Focus ST Rear Motor Mount is unique compared to our competitors mounts both in form and in function. We have incorporated a unique method of holding the mount in the vehicle.

Focus ST Rear Motor Mount Features

• Billet CNC construction
• EPDM Bushing
• CNC lathed aluminum bushing spacers
• Stabilize the engine rotational movement
• 65A or 75A durometer options
• All necessary hardware included

Instead of placing all of the force on the center bushing pin, the load is distributed throughout the bushing with the CNC lathed aluminum spacers. This load distribution increases the effective stiffness of the bushing under engine loads allowing a lower durometer bushing to provide more stiffness.

cp-e™ goes a step further 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 Focus rear motor mount is a perfect example of when not to use urethane. 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.
