Prothane 7-2005-BL Complete Polyurethane Suspension Bushing Total Kit Black

The Prothane 7-2005-BL Total Kit is a comprehensive polyurethane suspension bushing replacement kit designed for the 1975–1979 Chevrolet Camaro and 1974–1975 Pontiac Firebird/Trans Am. This all-in-one kit replaces every serviceable suspension bushing on the vehicle in a single purchase, eliminating the need to source individual components separately.

Prothane's polyurethane material is significantly firmer than the factory OEM rubber bushings, delivering improved suspension geometry consistency, sharper steering response, and enhanced chassis feedback. While the stiffer compound may result in a modest increase in NVH (noise, vibration, and harshness) compared to soft OEM rubber, the gains in handling precision and component longevity far outweigh this tradeoff for performance-minded drivers.

The -BL designation indicates black polyurethane. Black Prothane bushings incorporate a small amount of graphite into the polyurethane compound, which can help minimize squeaking during operation. Both black and red Prothane bushings share the same durometer (hardness rating) and deliver identical performance characteristics.

Kit Highlights:

• Complete suspension bushing kit — everything Prothane offers for this application in one package
• Black polyurethane construction with graphite additive for reduced squeaking
• Firmer than OEM rubber for improved handling and suspension responsiveness
• Outlasts factory rubber bushings for long-term durability
• Includes Prothane Super Grease for proper bushing lubrication during installation
• Backed by Prothane's Lifetime Warranty against defects in materials and workmanship

Each bushing must be properly lubricated with the included Super Grease during installation to prevent squeaking and ensure optimal service life. This kit is an ideal solution for restoring or upgrading the suspension on classic GM F-Body platforms.
