Whiteline W63420 Trailing Arm Bushing Kit

The Whiteline W63420 is a high-performance trailing arm bushing kit engineered to restore and improve rear suspension geometry, handling precision, and ride quality. Whiteline's bushings are a direct replacement for worn or deteriorated factory rubber bushings, offering superior durability and performance characteristics.

Manufactured from Whiteline's proprietary polyurethane compound, these trailing arm bushings resist compression, degradation from oils and chemicals, and the wear associated with high-stress suspension cycles. Unlike OEM rubber bushings that deflect under load and allow unwanted axle movement, Whiteline's polyurethane construction maintains consistent suspension geometry for more predictable handling and improved tire contact with the road surface.

Key Features:

• Polyurethane construction for superior durability over OEM rubber
• Resists oil, grease, and chemical degradation
• Reduces unwanted trailing arm flex and deflection
• Helps restore and maintain correct rear suspension alignment
• Direct OEM replacement — no modifications required
• Includes all hardware and grease needed for installation
• Designed and engineered in Australia by suspension specialists

Whiteline is a globally recognized leader in suspension components, with decades of engineering experience in bushings, sway bars, and alignment correction products. The W63420 is precision-manufactured to exact tolerances, ensuring a proper fit and long service life even under demanding driving conditions.
