The SPL Parts Rear Spherical Knuckle Bushing Kit is a high-performance upgrade designed for the 2017-2023 BMW 440i Gran Coupe (F36). This kit replaces the factory rubber bushing that attaches the lower control arm to the knuckle with a low-friction, Teflon-lined spherical bearing, enhancing suspension response and reducing deflection under heavy loads. Constructed with a machined housing and utilizing the largest FK bearing possible, it offers increased durability, longevity, and reduced noise, vibration, and harshness. This upgrade improves handling precision and stability, especially during aggressive driving or track use, by minimizing unwanted movement in the suspension components.

Specifically engineered for the F36 chassis, this bushing kit is a direct replacement for the OEM components, ensuring a straightforward installation process. It is suitable for street, track, and performance driving applications where improved suspension articulation and responsiveness are desired. The kit includes all necessary components for installation, providing a reliable upgrade for enthusiasts seeking enhanced control and reduced suspension bind. Compatibility is optimized for the specified model years and chassis, making it an ideal choice for those looking to upgrade their vehicle’s suspension performance.

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.
