Prothane 8-2015-BL Total Polyurethane Suspension Bushing Kit Black with Upper

The Prothane 8-2015-BL Total Kit is a comprehensive polyurethane suspension bushing replacement kit engineered for the 1999–2000 Honda Civic Si. This all-in-one kit consolidates everything Prothane offers for this platform into a single package, making a complete suspension bushing overhaul straightforward and cost-effective.

Prothane's polyurethane compound is significantly firmer than OEM rubber, delivering improved chassis feedback, sharper handling response, and greater longevity. While factory rubber bushings are prone to degradation from wear, UV exposure, road grime, and vehicle fluids, polyurethane resists these conditions to maintain consistent suspension geometry over time.

Kit Includes:

• Ball joint boots
• Front and rear control arm bushings (upper and lower)
• Shifter bushing
• Shock bushings
• Sway bar bushings
• Tie rod boots
• Prothane Super Grease lubricant for installation

Key Features:

• Black polyurethane construction — same durometer as red; graphite content may help reduce squeaking
• Firmer than OEM rubber for improved suspension performance and handling precision
• Long service life — resistant to oils, UV rays, and road contaminants that degrade factory rubber
• Includes Prothane Super Grease — proper lubrication at installation is essential to prevent bushing noise
• Lifetime warranty — Prothane guarantees against defects in materials and workmanship for the life of the vehicle under original ownership

Replacing the full complement of suspension bushings at once ensures all components perform consistently together, maximizing the handling improvement and keeping it consistent for years of driving.
