Prothane 8-1129-BL 17mm Rear Sway Bar Bushing Kit Black

The Prothane 8-1129-BL is a 17mm rear stabilizer bar bushing kit precision-engineered from premium-grade polyurethane—a significant upgrade over the soft, compliance-focused rubber bushings found on the factory sway bar. Sold as a pair, these black polyurethane bushings restore and improve the effectiveness of the OEM rear anti-roll bar by reducing unwanted flex and body roll.

Key Features:

• Premium polyurethane construction — firmer than OEM rubber for improved suspension response and reduced body roll
• Grooved bore design — engineered to retain Prothane's super grease for smooth, quiet operation
• Precision-fabricated fit — dimensioned to 17mm bore for an accurate, rattle-free installation
• Black color finish — discreet appearance that blends with factory underbody components
• Sold in pairs — complete kit for a full rear sway bar bushing replacement
• Compatible with larger-diameter performance sway bars — also available in sizes to suit high-performance aftermarket bars

Prothane polyurethane suspension components are a trusted choice among enthusiasts looking for improved handling precision without sacrificing everyday drivability. The 8-1129-BL installs using standard hand tools and requires no permanent modifications.
