Whiteline W63684 Rear Upper Trailing Arm Outer Bushing Kit

The Whiteline W63684 Rear Upper Trailing Arm Outer Bushing Kit is an engineered suspension upgrade designed to replace worn or degraded factory rubber bushings in the rear upper trailing arm position. This kit utilizes Whiteline's advanced polyurethane formulation to provide superior durability, improved suspension geometry retention, and enhanced handling characteristics compared to OEM rubber components.

Key Features:

• High-performance polyurethane construction resists wear, oil, and road contaminants
• Reduces rear suspension deflection under cornering and acceleration loads
• Maintains proper suspension alignment for improved tire contact and handling precision
• Direct replacement design for simplified installation
• Includes all necessary bushings and components for outer trailing arm mounting points
• Backed by Whiteline's limited lifetime warranty

This bushing kit is ideal for enthusiasts seeking to restore or improve their vehicle's handling performance by eliminating the compliance and deterioration common in aging rubber suspension bushings. The firmer polyurethane material provides more consistent suspension response while still offering adequate NVH (noise, vibration, harshness) isolation for street use.
