Prothane 1-1109 Rear Stabilizer Bar Bushing Kit 5/8 in. Polyurethane

The Prothane 1-1109 is a rear stabilizer bar bushing kit designed to replace the factory rubber bushings on your sway bar with high-performance polyurethane. OEM rubber bushings are prone to deflection and deterioration over time, allowing the stabilizer bar to shift under load and reducing its effectiveness. Prothane's firm polyurethane material restores and enhances sway bar performance for improved cornering stability and handling precision.

Key Features:

• Fits 5/8 in. diameter stabilizer bars
• Made from firm polyurethane for superior durability over stock rubber
• Grooved bore design retains Prothane Super Grease for quiet, squeak-free operation
• Resists compression set, oil, ozone, and weathering
• Direct OEM replacement — no modifications required
• Compatible with larger-diameter high-performance aftermarket sway bars of the same diameter
• Fits 1993–1998 applications (see fitment guide for specific vehicles)

Each bushing features Prothane's signature grooved inner bore, engineered to hold their proprietary Super Grease lubricant, ensuring smooth, rattle-free performance over the long term. Upgrading to Prothane polyurethane bushings is one of the most cost-effective suspension improvements available, delivering a noticeable improvement in body roll control and steering response.
