Prothane 19-1131-BL Sway Bar Bushing 13/16" Black Polyurethane

The Prothane 19-1131-BL is a 13/16" diameter black polyurethane sway bar bushing designed to replace soft, worn OEM rubber bushings on stabilizer bar "B" bracket applications. Upgrading to Prothane polyurethane delivers a noticeable improvement in handling response, body roll reduction, and overall suspension performance.

Key Features:

• 13/16" bore diameter — fits standard and "B" bracket stabilizer bar applications
• Grooved inner bore — engineered to retain Prothane Super Grease for smooth, quiet operation
• Firm polyurethane construction — resists compression and deflection far better than OEM rubber
• Black finish — durable, UV-resistant coloring that maintains appearance over time
• Direct OEM replacement — designed for straightforward installation in factory bushing locations
• Also compatible with larger-diameter high-performance sway bars — adaptable for performance upgrades

Prothane polyurethane bushings are formulated to outlast conventional rubber while tightening up suspension slop. The result is sharper steering feel, reduced body roll in cornering, and a more connected driving experience without sacrificing daily drivability.
