Trailing Arm Bushings

Whiteline Performance Trailing Arm Bushings (W63666) are engineered components designed to restore chassis rigidity and improve suspension geometry in performance-oriented vehicles. These bushings are critical pivot points that connect the trailing arm to the chassis, controlling rear axle movement and lateral location. They are essential for automotive enthusiasts or mechanics seeking to eliminate suspension slop and restore factory geometry.

The bushings are designed to withstand higher loads and frequency cycling compared to OEM rubber, while maintaining ride quality. They resist degradation from UV exposure, heat cycling, and chemical contamination—common failure modes in factory components. By reducing bushing deflection, these parts tighten rear axle location and improve suspension response, delivering more predictable handling characteristics under various driving conditions.

Vehicle owners experiencing vague rear-end feel, tire feathering, or audible suspension noise will benefit from these bushings. They ensure seamless integration into existing trailing arm assemblies without modification to mounting points or suspension geometry. A four-wheel alignment is recommended after installation for optimal performance.
