The SPL Parts Rear Spherical Knuckle Bushing Kit for the 2018 BMW 318i (F30) is a high-performance upgrade designed to replace the factory rubber bushing on the rear traction arm. This kit features a low-friction, Teflon-lined spherical bearing that enhances suspension response by reducing deflection under heavy loads and minimizing bind during suspension travel. Constructed with a machined housing and utilizing the largest FK bearing possible, it offers increased durability, longevity, and improved handling characteristics. The design aims to deliver a more direct connection between suspension components, resulting in sharper steering response and better overall stability.

This bushing kit is compatible with the 2012-2015 BMW 335i (F30), fitting the rear traction arm attachment points. It is intended for use in performance applications such as track days, spirited driving, or aggressive street use, where precise suspension tuning is desired. The installation involves replacing the OEM rubber bushing with this spherical bearing assembly, providing a direct upgrade for improved suspension performance. The kit includes all necessary components for a straightforward bolt-on installation, making it suitable for enthusiasts seeking enhanced control and reduced NVH during 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.
