Prothane 19-1115 Polyurethane Sway Bar Bushing - 16mm

Upgrade your vehicle's handling and stability with the Prothane 19-1115 polyurethane sway bar bushing, designed as a direct replacement for the soft, worn OEM rubber bushings on your stabilizer (anti-roll) bar. Engineered to fit a 16mm diameter sway bar with a bracket-style mount, this bushing delivers a noticeable improvement in cornering response and body roll control.

Prothane's proprietary polyurethane compound is significantly firmer than stock rubber, reducing unwanted flex and slop that robs your sway bar of its effectiveness. The bushing features a grooved inner bore specifically designed to retain Prothane's Super Grease, ensuring quiet, squeak-free operation throughout its service life — a common drawback with lesser polyurethane parts.

Key Features:

• Fits 16mm diameter stabilizer bars with bracket-style mounting
• Precision-molded polyurethane construction for superior durability over OEM rubber
• Grooved bore designed to retain Prothane Super Grease for quiet operation
• Improves sway bar responsiveness and reduces body roll
• Resists oils, solvents, and road chemicals that degrade rubber over time
• Direct OEM replacement — no modifications required
• Made in the USA

Prothane polyurethane bushings are a proven performance upgrade for enthusiasts seeking sharper handling without sacrificing daily driveability. Whether restoring worn-out suspension geometry or building a performance-oriented street car, the Prothane 19-1115 is a straightforward, cost-effective improvement over factory rubber components.
