Fits select 2013-2020 Lexus GS F, GS200t, GS300, GS350, and GS450h.

Control arm bushings serve as the critical pivot points for your vehicle's suspension. Worn factory bushings allow for significant deflection, leading to vague steering response, irregular tire wear, and a diminished driving experience. These issues are often exacerbated in vehicles equipped with larger wheels, grippy tires, or upgraded braking systems. The SuperPro SPF4327K kit replaces these soft or failed components with high-performance polyurethane for sharper handling and long-term reliability.

SuperPro bushings are engineered and manufactured in Australia using a proprietary, engineering-grade polyurethane formula. Unlike standard rubber, this material is unaffected by oils, water, or extreme temperatures, ensuring the suspension geometry remains consistent under load. Despite the increased durability, SuperPro designs focus on maintaining OEM-level noise, vibration, and harshness (NVH) isolation, making this kit ideal for both daily commutes and spirited driving.
