The SPL Parts Rear Spherical Knuckle Bushing Kit is a high-performance upgrade designed for the 2017-2019 BMW 330i 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, enhancing suspension response and durability. The use of the largest FK bearing in this application ensures increased longevity and reduced NVH (noise, vibration, harshness). The machined housing provides precise fitment and robust construction, resulting in improved handling characteristics and reduced deflection under heavy loads. This upgrade is ideal for enthusiasts seeking improved suspension articulation and more precise steering feedback during spirited driving or track use.

Designed specifically for the 2017-2019 BMW 330i xDrive models, this bushing kit is a direct replacement for the OEM components. It offers a bolt-on installation that does not require extensive modifications, making it suitable for street and track applications. The kit enhances suspension performance by minimizing bind and allowing for more consistent control arm movement through the suspension travel. Compatibility is limited to the specified model years and chassis, ensuring optimal fitment and function. This component is perfect for those looking to upgrade their vehicle’s handling and suspension response with a durable, high-quality solution.

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.

Standard Features
