The SPL Parts Rear Spherical Knuckle Bushing Kit is a high-performance upgrade designed for the 2014-2018 BMW 328d xDrive (F30/F31). This kit replaces the factory rubber bushing that attaches the lower control 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 bind during suspension travel. Constructed with a machined housing and utilizing the largest FK bearing possible, this bushing offers increased durability, lower noise, vibration, and harshness (NVH), and improved handling characteristics. It is engineered to provide a more direct and responsive connection between suspension components, making it ideal for performance driving and track use.

Designed specifically for the F30/F31 chassis, this bushing kit fits 2014-2018 BMW 3 Series models with the N20 and N55 engines. It serves as a direct replacement for the OEM component, ensuring proper fitment and function. The kit is intended for street, track, or spirited driving, offering a significant upgrade over stock bushings by reducing flex and improving steering precision. Installation involves replacing the existing bushings with the spherical bearing units, and no additional modifications are required. This upgrade is suitable for enthusiasts seeking enhanced suspension performance and durability in their BMW 3 Series.

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.
