Prothane 6-1163 Rear Sway Bar Bushing Kit 18mm Polyurethane 2005+

Upgrade your suspension performance with the Prothane 6-1163 rear stabilizer bar bushing kit, designed as a direct replacement for worn or mushy OEM rubber bushings. Engineered for mustang convertibles (2005 and newer), this 18mm kit installs onto the rear sway bar to deliver more precise handling and reduced body roll.

Prothane's polyurethane compound is significantly firmer than stock rubber, translating driver inputs more directly to the chassis and improving overall cornering stability. The bushings feature grooved bores that are specifically designed to retain Prothane's Super Grease, ensuring quiet, squeak-free operation over the long term.

Key Features:

• Made from firm, durable polyurethane for improved performance over OEM rubber
• Grooved bore design holds lubrication for quiet, long-lasting operation
• 18mm inner diameter — fits 2005 and newer rear stabilizer bars
• Direct OEM replacement with no cutting or modification required
• Compatible with larger-diameter high-performance aftermarket sway bars
• Includes Prothane Super Grease for installation and long-term lubrication

Prothane polyurethane bushings resist oils, solvents, and road grime while maintaining their performance characteristics far longer than conventional rubber. Whether you're restoring handling precision on a daily driver or building a dedicated performance vehicle, the Prothane 6-1163 is a cost-effective suspension upgrade that makes a noticeable difference behind the wheel.
