Prothane 7-1181-BL Rear Sway Bar Bushing Kit 23.6mm Black

The Prothane 7-1181-BL is a rear stabilizer bar bushing kit designed as a direct-fit polyurethane upgrade for the C5 Corvette. Replacing the factory rubber bushings with Prothane's premium-grade polyurethane compound delivers a measurable improvement in handling precision and body roll control — performance that stock rubber simply cannot match.

Prothane's polyurethane formula provides the necessary rigidity to maximize sway bar effectiveness, tightening chassis response and reducing body roll without the noise and slop associated with worn OEM rubber. Each bushing features grooved bores engineered to retain Prothane's proprietary super grease, ensuring long-lasting quiet operation throughout the life of the bushing.

Key Features:

• Premium-grade polyurethane construction — significantly firmer than OEM rubber
• 23.6mm bore diameter — precision-fabricated for a perfect fit
• Grooved inner bore designed to hold Prothane super grease for quiet, squeak-free operation
• Black finish
• Direct-fit replacement — no modifications required
• Also compatible with larger-diameter high-performance aftermarket sway bars

Prothane polyurethane suspension components are a proven upgrade over soft factory rubber, delivering superior handling and durability. The 7-1181-BL is an excellent addition to any suspension refresh or performance build on the C5 Corvette platform.
