The SPL Parts Rear Spherical Knuckle Bushing Kit is a high-performance upgrade designed for the rear traction arm knuckles on BMW F30 models from 2014 to 2018. This kit replaces the factory rubber bushings with low-friction, teflon-lined spherical bearings, significantly reducing deflection under heavy loads and minimizing bind during suspension travel. Constructed with precision-machined housings and the largest FK bearings available, these bushings enhance durability, improve handling response, and lower noise, vibration, and harshness for a more connected driving experience.

Specifically engineered for 2014-2018 BMW 328d models, this kit is a direct replacement for the OEM components on the rear traction arm knuckles. It is suitable for street and track use, providing increased stability and responsiveness during aggressive driving or spirited cornering. The installation involves replacing the factory bushings with these spherical bearings, offering a maintenance-friendly upgrade that maximizes suspension performance. This kit is ideal for enthusiasts seeking improved handling and longevity in their BMW's rear suspension system.

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.
