Prothane 4-217-BL Front Control Arm Polyurethane Bushing Kit Black

The Prothane 4-217-BL is a front control arm bushing kit engineered in black polyurethane as a direct performance upgrade over worn or soft factory rubber bushings. Worn OEM rubber bushings allow excessive control arm movement, throwing off caster, camber, and toe settings and degrading steering response. Prothane's polyurethane compound delivers significantly greater compliance resistance, keeping the control arms firmly located for precise, repeatable alignment geometry.

Key Features:

• Polyurethane construction — firmer than OEM rubber for improved handling response and longer service life
• Black color with graphite additive — helps reduce squeaking when properly lubricated at installation
• Superior compliance resistance — minimizes control arm deflection to maintain accurate alignment settings under load
• Sold as a complete kit — includes all bushings needed for the front control arms
• Supplied pre-lube included — grease bushings at install to ensure quiet, long-lasting operation
• Lifetime warranty — Prothane guarantees the product against defects in materials and workmanship for the life of original ownership

Prothane polyurethane suspension components are a trusted performance upgrade for drivers looking to restore or improve suspension precision. Proper lubrication at installation is essential for optimal performance and to prevent noise.
