The SPL Parts Rear Spherical Knuckle Bushing Kit for the 2017-2021 BMW M240i xDrive (F22/F23) is a high-performance upgrade designed to enhance suspension responsiveness and durability. 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 use of a large FK bearing ensures increased longevity and reduced NVH, providing a more direct connection between suspension components. The machined housing for the bearing offers precise fitment and robust construction, resulting in improved handling characteristics under heavy loads and aggressive driving conditions. This upgrade minimizes deflection and bind, translating to sharper steering response and more predictable suspension behavior.

Designed specifically for the F22 and F23 chassis, this bushing kit is an ideal upgrade for track enthusiasts, spirited drivers, or those seeking to improve overall suspension performance. It replaces the OEM component with a direct bolt-on solution that maintains proper alignment and fitment. The kit is suitable for street and track use, offering enhanced control and reduced suspension flex during cornering. Installation involves replacing the existing factory bushing with the spherical bearing assembly, ensuring a secure and reliable upgrade. This product is compatible with the specified BMW models and is intended for those looking to optimize their vehicle’s handling and suspension precision.

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.
