Description
The SuperPro Rear Trailing Arm Forward and Rearward Bushing Set (Part Number: sprSPF4314K) is designed to improve suspension control, reduce unwanted suspension movement, and help maintain consistent handling in compatible BMW vehicles. This lower trailing arm bushing kit replaces worn suspension bushings that can allow excessive deflection, slower steering and handling responses, an unstable driving feel, and irregular or excessive tire wear.
SuperPro polyurethane bushings are developed using nearly five decades of suspension expertise and testing in Australia's demanding terrain. Durability is a key design priority, while ride comfort, passenger comfort, and cabin noise isolation remain important considerations. SuperPro's material compositions and designs aim to retain OEM-level noise and harshness isolation while delivering enhanced suspension performance and reliable road manners in a variety of driving conditions.
Worn bushings can have an even greater impact on vehicles equipped with wider or grippier tires, larger or heavier wheels, upgraded brakes, and other performance modifications. This bushing set provides a suspension repair or upgrade solution for compatible BMW applications, helping maintain suspension geometry and consistent vehicle behavior during everyday driving and performance use.
