The SPL Parts Rear Spherical Knuckle Bushing Kit is a high-performance upgrade designed for the 2020-2021 BMW M135i (F20). This kit replaces the factory rubber bushing that attaches the rear traction arm to the knuckle with a low-friction, teflon-lined spherical bearing. The upgrade enhances suspension response by reducing deflection under heavy loads and minimizing binding as the suspension moves through its travel. Constructed with a machined housing and utilizing the largest FK bearing possible, this kit offers increased durability, longevity, and reduced NVH for a more precise and responsive driving experience.

Specifically engineered for the F20 chassis, this bushing kit is an ideal upgrade for enthusiasts seeking improved handling and suspension feel. While originally designed for the M135i, it shares compatibility with similar chassis configurations, providing a direct replacement for the OEM component. The kit is suitable for street and track use, offering a significant upgrade over stock bushings by providing more consistent suspension geometry and reduced flex. Installation involves replacing the factory bushing with the spherical bearing assembly, ensuring a secure fit and enhanced performance in demanding driving conditions.

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.
