Prothane 7-1141-BL Rear Stabilizer Bar Bushing Set 7/16 in. Black Polyurethane

The Prothane 7-1141-BL is a rear stabilizer bar bushing set designed to replace the factory rubber bushings on 1963–1982 Corvettes. Prothane's polyurethane construction delivers a significant upgrade over OEM soft rubber, reducing bushing deflection for improved handling, body control, and sway bar responsiveness.

Key Features:

• Polyurethane material — firmer than stock rubber for enhanced anti-roll bar performance and reduced body roll
• Grooved bore design — engineered to retain Prothane Super Grease, ensuring quiet, squeak-free operation
• 7/16 in. bore diameter — precision-fit for correct OEM stabilizer bar sizing
• Black finish — color-coded for easy identification and a clean under-vehicle appearance
• Also compatible with larger-diameter high-performance sway bars — suitable for performance upgrades beyond stock bar sizing
• Direct replacement — no cutting, trimming, or modification required for stock applications

Prothane polyurethane bushings are a proven suspension upgrade for enthusiasts seeking better handling without sacrificing street drivability. Each set includes all bushings needed for a complete rear stabilizer bar installation.
