Prothane 7-1189-BL Corvette Rear Sway Bar Bushing 23mm Black Polyurethane

Upgrade your Corvette's handling with the Prothane 7-1189-BL rear stabilizer bar bushings, a direct replacement for worn or soft factory rubber bushings. Designed for 2005–2006 Corvette applications with a 23mm rear sway bar, these polyurethane bushings deliver a noticeable improvement in body roll control and cornering response over OEM rubber.

Prothane's polyurethane compound is significantly firmer than stock rubber, reducing sway bar deflection and transferring more of the bar's anti-roll force to the suspension — exactly where it's needed. Each bushing features a grooved inner bore engineered to retain Prothane's included super grease, ensuring quiet, squeak-free operation over the long term.

Key Features:

• Designed to fit 23mm rear stabilizer bars on 2005–2006 Corvette
• Manufactured from firm, long-lasting black polyurethane (color code: BL)
• Grooved bore retains lubrication for reduced noise and friction
• Reduces body roll and improves lateral stability compared to OEM rubber bushings
• Direct OEM replacement — no drilling or modification required

Whether you're looking to sharpen everyday driving dynamics or support a performance-oriented suspension build, the Prothane 7-1189-BL offers a cost-effective, bolt-in upgrade over the mushy factory bushings. Sold as a set.
