Prothane 7-2005 Total Polyurethane Suspension Bushing Kit

The Prothane 7-2005 Total Kit is a comprehensive polyurethane suspension bushing replacement kit designed for the GM F-Body platform. This all-in-one solution bundles every vehicle-specific bushing Prothane offers into a single part number, making it the ideal choice for a complete suspension refresh.

Prothane's polyurethane material is firmer than factory rubber bushings, delivering improved suspension precision and longer service life. While OEM rubber bushings are engineered to soften road noise and vibration, they wear out and degrade over time — causing vague handling and increased chassis flex. Upgrading to polyurethane restores and exceeds original suspension performance, with only a minimal increase in NVH (noise, vibration, and harshness) as a trade-off for the handling gains.

Key Features:

• Complete vehicle-specific polyurethane bushing kit — everything in one part number
• Firmer than OEM rubber for improved chassis feedback and handling precision
• Longer service life compared to factory rubber bushings
• Available in red or black — identical durometer and performance in both colors
• Includes Prothane Super Grease for proper lubrication during installation
• Backed by Prothane's Lifetime Warranty for the original purchaser

Kit typically includes front and rear control arm bushings, ball joint boots, tie rod boots, sway bar bushings, sway bar end links, spring and shackle bushings, drivetrain bushings, and transmission mount (exact contents vary by application). Super Grease is included — proper lubrication at installation is essential to prevent squeaking.
