Prothane 18-1119-BL Front Sway Bar Bushing Kit 27.2mm Black

The Prothane 18-1119-BL is a front sway bar bushing kit designed to replace the factory rubber bushings on the Lexus IS300. This kit includes 2 polyurethane bushings sized for a 27.2mm (1.07") front sway bar, offering a direct, performance-oriented upgrade over stock components.

OEM rubber sway bar bushings are prone to warping and cracking over time, causing the sway bar to lose its grip and effectiveness. Prothane's polyurethane construction resists deterioration from road grime, weather, and oils — delivering a consistently firm, secure hold on the sway bar throughout the life of the vehicle.

Key Features:

• Material: High-durometer polyurethane — significantly firmer and more durable than factory rubber
• Bar Diameter: Fits 27.2mm (1.07") front sway bars
• Color: Black (graphite-infused polyurethane for added noise reduction)
• Grooved Bore Design: Engineered to retain Prothane Super Grease for quiet, squeak-free operation
• Kit Includes: 2 sway bar bushings and Prothane Super Grease (brackets not included)
• Warranty: Lifetime warranty against defects in materials and workmanship for the original purchaser

By maintaining a tighter, more consistent grip on the sway bar, these polyurethane bushings help reduce body roll and improve cornering response — delivering handling performance similar to installing a larger-diameter sway bar. Grease the bushings thoroughly at installation using the included Super Grease to ensure quiet, long-lasting performance.
