These Rear Traction Arm Knuckle Bushing replace the rubber factory bushing attaching the lower control arm to the knuckle with a low friction teflon-lined spherical bearing. Replacing the OEM component with this bushing will allow for less deflection under heavy load, and less bind as the arm travels through its suspension. We use the largest possible FK bearing in this location for increased longevity and lower NVH.
Fits: BMW M240i (F22), BMW 440i (F32), BMW 340i (F30). Confirm fitment with us before ordering.
