Prothane 8-1139 Front Stabilizer Bar Bushing Kit 27mm Polyurethane

The Prothane 8-1139 is a front stabilizer bar bushing kit designed as a direct upgrade over worn or soft factory rubber bushings. Engineered from Prothane's signature polyurethane compound, these 27mm bushings deliver improved sway bar responsiveness and more precise handling characteristics compared to stock replacements.

OEM rubber stabilizer bar bushings are prone to deflection and deterioration over time, reducing the effectiveness of the anti-roll bar and introducing slop into the suspension. Prothane's polyurethane construction resists compression, maintaining consistent sway bar geometry and improving chassis response during cornering.

Key Features:

• 27mm bore diameter — fits the factory front stabilizer bar
• Polyurethane construction — firmer than OEM rubber for improved handling and reduced body roll
• Grooved bore design — retains Prothane Super Grease for smooth, squeak-free operation
• Direct OEM replacement — installs in the factory bracket locations with no modifications
• Also compatible with larger diameter high-performance aftermarket sway bars
• Resists oil, ozone, and temperature extremes better than rubber

Each kit includes the polyurethane bushings and is compatible with Prothane Super Grease for long-lasting, noise-free performance. Prothane polyurethane suspension components are a proven upgrade for street and performance driving applications.
