SuperPro Rear Upper Control Arm Outer Bushing Kit for 2000-2009 Subaru Legacy & Outback (SPF3389K)

Fits select 2000-2009 Subaru Legacy and Outback models.

Control arm bushings serve as the critical pivot points between your core suspension components. When factory rubber bushings wear out, they allow excessive deflection, leading to steering wander, slow suspension response, and irregular tire wear. The SuperPro SPF3389K kit is designed to replace these worn components with a high-performance, engineering-grade polyurethane alternative that restores steering precision and vehicle stability.

Developed and manufactured in Australia to withstand harsh environments, these bushings maintain OEM levels of noise, vibration, and harshness (NVH) isolation while providing superior durability. Unlike rubber, SuperPro’s proprietary polyurethane formula is resistant to extreme temperatures, oils, water, and coolant, ensuring consistent performance for the life of the vehicle.
