Whiteline W63585 Trailing Arm Upper Front Bushing - Live Rear Axle Suspension Upgrade

The Whiteline W63585 is a replacement upper front trailing arm bushing engineered for vehicles with live rear axle suspension systems. Whiteline's performance bushings are manufactured from a proprietary polyurethane compound that outperforms stock rubber bushings in durability, responsiveness, and driveline efficiency.

Whether you're replacing worn or failed factory bushings, completing a classic vehicle restoration, or looking to sharpen suspension feel and improve power transfer to the wheels, this bushing delivers measurable improvements over OEM rubber. The firmer compound reduces unwanted axle movement and deflection under acceleration and braking, keeping wheel alignment more consistent throughout the suspension travel.
