Whiteline KCA422 Radius Arm Lower Bushing - Kit

The Whiteline KCA422 is a high-performance radius arm bushing kit engineered to enhance your vehicle's handling characteristics through improved caster geometry. This lower bushing replacement increases static caster angle and promotes dynamic negative camber gain during cornering, resulting in superior grip and more predictable handling behavior.

Key Features:

• Synthetic elastomer bushing material for superior durability and performance
• Increases static caster for improved straight-line stability
• Enhances dynamic negative camber gain during cornering
• Provides sharper steering response and improved feedback
• Reduces bushing deflection under braking for better brake performance
• Direct replacement for worn or deteriorated factory radius arm bushings

Whiteline's advanced elastomer formulation resists deterioration from oils, road chemicals, and UV exposure while maintaining consistent performance across a wide temperature range. The increased caster angle improves directional stability at highway speeds while the improved camber curve maximizes tire contact patch during aggressive cornering.
