SPL Parts Rear Spherical Knuckle Bushing Kit

Fitment: 1996-1999 BMW 328is (E36)

Part #: SPL RKB E36

Overview

The SPL Parts Rear Spherical Knuckle Bushing Kit is a high-performance upgrade designed specifically for the BMW E36 chassis, including the 1996-1999 328is model. This kit replaces the factory rubber bushings with precision-engineered spherical bearings, providing a more direct and responsive connection between the suspension components and the chassis. Ideal for enthusiasts and racers seeking improved handling, reduced flex, and enhanced feedback, these bushings help maintain optimal suspension geometry under load, resulting in more predictable and confident driving dynamics. Crafted for durability and performance, they support aggressive driving styles and track use while offering long-lasting reliability.

Key Features

This kit features high-quality materials and a design focused on performance and longevity. The spherical bearings are constructed with FK Racing Bearings, incorporating a self-lubricating Teflon liner for minimal maintenance and maximum durability. The monoball design ensures precise articulation and minimal deflection, translating to sharper steering response and improved cornering stability. The bushings are engineered to eliminate bushing flex and reduce bind and friction, helping your suspension respond more accurately to driver inputs. The robust construction supports consistent handling and feedback, making it an excellent upgrade for performance-oriented applications.

Construction & Design

The spherical knuckle bushings are machined from durable materials with a focus on structural integrity and precise fitment. The self-lubricating Teflon liners within the FK bearings ensure smooth operation over time, resisting wear and contamination. The monoball design provides a solid, stable connection that maintains suspension geometry under load, reducing unwanted movement and enhancing overall handling performance.

Installation & Fitment

Installation requires basic suspension tools and mechanical knowledge. The kit is designed as a direct bolt-in replacement for the stock bushings, simplifying the upgrade process. Proper alignment and torque specifications should be followed to ensure optimal performance and longevity.

What’s Included

The package includes all necessary spherical bearings, mounting hardware, and installation instructions to complete the upgrade efficiently.

Ideal For

Perfect for track days, autocross, or spirited street driving, this bushing kit is ideal for drivers looking to maximize suspension responsiveness and handling precision on their BMW E36.
