Prothane 8-322-BL Billet Aluminum Rear Compensator Arm Kit - Black

The Prothane 8-322-BL is a complete rear compensator arm kit featuring two billet aluminum arms with Prothane's high-performance black polyurethane bushings pre-installed. Designed as a direct bolt-on upgrade over worn factory compensator arms, this kit addresses common rear suspension issues including handling instability and uneven tire wear.

Key Features:

• Billet aluminum construction — lightweight yet exceptionally durable, providing a significant strength advantage over OEM stamped steel arms
• Pre-installed black polyurethane bushings — no press required for installation; simply remove the factory arms and bolt these on
• Graphite-infused polyurethane — the black bushing compound includes a small amount of graphite to help reduce friction and minimize squeaking
• Superior to stock rubber — polyurethane resists compression, deterioration, and deflection far better than factory rubber bushings, maintaining proper suspension geometry over time
• Lifetime warranty — Prothane backs this kit against defects in materials and workmanship for the life of the vehicle with the original purchaser
• Includes Prothane logo branding — features the Prothane logo on the billet arms for a finished appearance

Installation is straightforward with no special press tools needed, thanks to the bushings being factory-fitted to the arms. For a complete rear suspension upgrade, this kit pairs directly with Prothane part number 8-321, the rear upper billet control arms. Available in black (8-322-BL) or red (8-322).
