Prothane 6-803-BL Rear Frame Shackle Bushing Kit Black

The Prothane 6-803-BL Rear Frame Shackle Bushing Kit provides a durable polyurethane upgrade for the factory rubber bushings on leaf spring suspensions. This kit is designed as a direct replacement for worn or deteriorated original equipment bushings that mount the rear leaf spring shackles to the frame.

Key Features:

• Premium grade polyurethane construction resists wear, road grime, and deterioration
• Precision fabricated components ensure proper fitment and alignment
• Black polyurethane formulation includes graphite additive to reduce potential squeaking
• Restores suspension performance and handling by eliminating bushing deflection
• Includes pre-lube grease for proper installation and quiet operation
• Backed by Prothane's lifetime warranty against defects

Polyurethane bushings offer superior durability compared to original rubber components, maintaining their shape and performance characteristics under the significant forces applied through leaf spring shackle mounting points. This kit helps restore proper ride height, improves load carrying capability, and provides more consistent suspension response.
