Description
Improve the suspension precision and handling of your Subaru WRX or WRX STI with the SuperPro Front Lower Inner DuroBall Control Arm Bushing Kit. Designed for standard alignment applications, this kit upgrades the lower inner rear control arm bushing location with SuperPro's DuroBall technology.
Control arm bushings are essential pivot points connecting the vehicle's suspension components. As factory bushings wear, excessive deflection and movement can develop, contributing to slower suspension response, imprecise handling, irregular or excessive tire wear, and a less controlled driving experience.
SuperPro's DuroBall assembly uses an isolated spherical bearing encased in polyurethane. This construction combines the precision and articulation of a bearing-style design with the noise, vibration, and harshness (NVH) mitigation provided by SuperPro's proprietary polyurethane compounds.
The effects of worn bushings can be more pronounced on vehicles equipped with larger or higher-grip tires, heavier wheels, upgraded brakes, and other performance modifications. Developed through nearly five decades of suspension expertise in Australia's demanding terrain, SuperPro bushings prioritize durability while maintaining ride comfort, passenger comfort, and cabin isolation.
SuperPro's material composition is designed to retain OEM-style noise and harshness isolation while delivering improved suspension performance and road manners in varied driving conditions.
