Upgrade your Lexus with the SuperPro Radius Arm Bushing Kit—precision-engineered to restore suspension geometry, improve steering stability, and enhance overall ride quality. Radius arm bushings play a critical role in maintaining caster alignment and controlling front-end movement under braking and acceleration. Over time, OEM rubber bushings degrade, leading to vague steering feel, inconsistent handling, and excessive suspension deflection. SuperPro's polyurethane bushings offer a durable, high-performance replacement that ensures lasting control and precision.

Improved Steering Stability: Maintains accurate caster alignment and reduces unwanted front-end movement under load, delivering more predictable handling.

Enhanced Suspension Geometry: Reduces deflection in the radius arm connection to preserve proper suspension alignment across various driving conditions.

Long-Lasting Durability: Constructed from SuperPro’s proprietary polyurethane for superior resistance to wear, heat, and chemicals.

Balanced Ride Comfort and Control: Engineered to minimize noise, vibration, and harshness (NVH) while providing a performance-oriented upgrade.

Ideal for Performance and Daily Driving: Whether you're building a performance setup or just looking for a reliable, long-term suspension solution, these bushings deliver.

Vehicle Fitment:

  • Lexus GS300 2001 - 2005
  • Lexus GS430 2001 - 2005
  • Lexus SC430 2002 - 2010
