BMW Front Upper Spring seat with Koyo Bearing - I-29-I-80-F-USS-KOYO

BC Racing utilizes the highest quality Koyo bearings available between the top plate and the top of the spring on applications that utilize camber upper mounts. It is a sealed and self lubricating bearing that is pressed into our upper spring seat during the assembly process. The 6061-T6 aluminum is milled down in the center and the Koyo is pressed in. A yellow zinc plated misalignment spacer is then used to mate the top of the Koyo bearing to our pillowball casing. The entire assembly allows rotational movement to decreases friction when the steering wheel turns. Without this bearing it is possible for the spring to bind during turning which creates a twang type spring sound.

Over time, exposure to weather and regular use can naturally wear down the bearing. When it’s time to refresh your setup, our replacement upper spring seats with the Koyo bearings are designed specifically for select coilover kits.
