Product Details
These Rear Traction Arm Knuckle Bushing for the 2017-2020 BMW 440i xDrive Gran Coupe (F36) 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. The housing for the bearing is machined out of 6061-T6 aluminum and is CNC cut to +/- .001" tolerance to insure proper fitment.
Made in the USA.
Features
- Improved Precision: Provides enhanced steering response and accuracy by reducing flex and play compared to traditional rubber bushings.
