The SPL Parts Rear Spherical Knuckle Bushing Kit for the 2017-2020 BMW 440i (F32/F33) is a high-performance upgrade designed to enhance suspension responsiveness and durability. This kit replaces the factory rubber bushings with low friction, teflon-lined spherical bearings, significantly reducing deflection under heavy loads and minimizing binding as the suspension moves through its range. Constructed with machined housings and large FK bearings, these bushings provide increased longevity, improved handling, and reduced NVH for a more connected driving experience. They are engineered to withstand aggressive driving conditions while maintaining precise suspension geometry.

Designed specifically for the rear traction arm of the F32/F33 chassis, these spherical knuckle bushings are a direct replacement for OEM components. They are ideal for track enthusiasts, spirited street driving, or any application requiring enhanced suspension performance. Installation involves replacing the stock rubber bushings with these spherical bearings, offering a bolt-on upgrade that does not require additional modifications. The kit includes all necessary components for a straightforward installation, ensuring a secure fit and long-lasting performance in demanding driving environments.

Overview

These Rear Traction Arm Knuckle Bushing for the 2012-2015 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. 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.
