SPL Parts Rear Spherical Knuckle Bushing Kit - 2013-2015 BMW 335i xDrive (F30) ksport-lower-control-arms Touring Chassis Code Z34 SpringThese Rear Traction Arm Knuckle Bushing for the 2013 2015 BMW 335i (F30) 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.
