Description
Upgrade the front suspension performance of your Subaru Impreza WRX STI with the SuperPro Front Lower Inner DuroBall Control Arm Bushing Kit. Designed for standard alignment applications, this DuroBall bushing assembly provides improved suspension precision, controlled articulation, and enhanced road manners compared with traditional elastomer bushings.
Control arm bushings serve as vital pivot points between the vehicle's core suspension components. Over time, worn factory bushings can allow excessive deflection and unwanted movement, resulting in slower suspension response, a less precise driving feel, irregular or excessive tire wear, and reduced overall handling performance.
SuperPro's DuroBall bushing assembly combines an isolated spherical bearing encased in polyurethane. This design delivers the precision and articulation associated with a bearing-style system while retaining the noise, vibration, and harshness (NVH) mitigation characteristics of SuperPro's specially formulated polyurethane compounds.
The effects of worn control arm bushings can become more noticeable on vehicles equipped with larger or higher-grip tires, larger or heavier wheels, upgraded brakes, and other performance modifications. SuperPro developed its polyurethane suspension components through nearly five decades of suspension expertise and development in Australia's demanding terrain.
Durability is a key part of the design, while ride comfort, passenger comfort, and cabin isolation remain important considerations. SuperPro's material composition is engineered to retain OEM-style noise and harshness isolation while delivering improved suspension performance and road manners in a wide range of driving conditions.
