Prothane 18-1128-BL Front Sway Bar Bushing Kit 30mm Black Polyurethane

The Prothane 18-1128-BL is a front sway bar bushing kit designed to fit a 30mm (1.18 inch) stabilizer bar. Finished in black, this bushing kit is manufactured from high-performance polyurethane — a significantly more durable material than the factory rubber bushings it replaces.

Why Upgrade to Polyurethane?

Original equipment rubber sway bar bushings can warp, crack, and lose their grip on the bar over time, diminishing the effectiveness of your front stabilizer bar. Prothane's polyurethane compound resists breakdown from road grime, weathering, and oils, maintaining a firm, consistent grip on the sway bar throughout the life of the part. The result is improved handling response and reduced body roll — delivering a performance boost comparable to installing a larger sway bar.

Key Features:

• Material: High-performance black polyurethane with graphite content to help resist squeaking
• Bar Diameter: 30mm (1.18 inch) front sway bar
• Position: Front
• Color: Black (BL)
• Grooved bore design engineered to retain Prothane Super Grease for quiet, long-lasting operation
• Lifetime warranty — Prothane guarantees the product to be free of defects in materials and workmanship for as long as the original purchaser owns the vehicle

Installation Note: The sway bar rotates inside the bushing during operation. Always lubricate the bore with the supplied Prothane Super Grease at the time of installation to ensure quiet performance and maximum longevity.
