Part #: SPL RKB E36

Overview

The SPL Parts Rear Spherical Knuckle Bushing Kit is a high-performance upgrade designed specifically for the 1992-1995 BMW 325i (E36). This kit replaces the stock rubber bushings in the rear knuckle with low-friction, articulating spherical bearings, offering a significant improvement over factory components. It is ideal for enthusiasts seeking enhanced handling, precise feedback, and consistent suspension geometry under load. Whether you are a track day enthusiast or a spirited driver, these bushings help maintain optimal alignment and reduce unwanted flex, resulting in a more responsive and predictable driving experience. Designed with durability and performance in mind, these monoball bushings feature FK Racing Bearings with a self-lubricating Teflon liner, ensuring long-lasting operation and minimal maintenance. The upgrade supports aggressive driving styles by reducing bushing flex and eliminating camber and toe change under load, which can negatively impact handling and tire wear. This product is engineered to help your BMW achieve sharper turn-in, improved stability, and more direct steering feel.
