Prothane 8-1142-BL Rear Sway Bar Bushing Kit 17mm Black

The Prothane 8-1142-BL is a rear sway bar bushing kit designed for 17mm sway bars. Constructed from high-performance polyurethane, this bushing delivers a significant upgrade over factory rubber components that are prone to cracking, warping, and losing their grip over time.

Why Upgrade to Polyurethane?

Original equipment rubber bushings can warp and crack with age, causing the sway bar to lose its effectiveness and reducing chassis stability. Prothane's polyurethane formula resists road grime, weathering, and oils — common culprits that degrade rubber over time. The result is a bushing that maintains a firm, consistent grip on the sway bar throughout its lifespan.

Key Features:

• 17mm bore diameter (0.66 inch) for precise fit on the rear sway bar
• Black polyurethane construction with a small amount of graphite blended in to help reduce squeaking
• Provides a secure, warp-resistant grip on the sway bar for improved handling response
• Resistant to road grime, weather, and oils — outlasts factory rubber bushings
• Includes Prothane Super Grease for proper lubrication during installation
• Backed by Prothane's Lifetime Warranty against defects in materials and workmanship

For best results and to prevent squeaking, apply the included grease to the bushing surface before installation. The black color variant shares the same durometer (hardness rating) as Prothane's red bushings, offering identical performance characteristics.
