Prothane 14-1105-BL Front Sway Bar Bushing Kit 18mm Black Polyurethane

The Prothane 14-1105-BL is a front stabilizer bar bushing kit engineered as a direct, performance-oriented replacement for worn or soft factory rubber bushings. Molded from premium-grade black polyurethane, these bushings deliver a firmer, more responsive connection between the sway bar and chassis compared to standard OEM rubber components.

Key Features:

• 18mm bore diameter — precision-fit for the factory front sway bar (0.70 inch)
• Black polyurethane construction — includes a small amount of graphite blended into the material to help resist squeaking
• Grooved bore design — engineered to retain Prothane Super Grease for quiet, long-lasting operation
• Resists degradation — polyurethane does not break down from road grime, oils, or weather exposure the way rubber does
• Performance upgrade — firmer bushing material provides a more secure grip on the sway bar, reducing body roll and improving handling response
• Kit coverage — one kit covers both left and right sides; fits 18mm bar diameter only
• Includes Prothane Super Grease — supplied lubricant should be applied at installation to prevent noise
• Lifetime warranty — Prothane guarantees against defects in materials and workmanship for the life of the vehicle under original ownership
• Made in the USA

Over time, OEM rubber sway bar bushings warp, crack, and lose their grip on the stabilizer bar, reducing the bar's ability to control body roll. Upgrading to Prothane's polyurethane bushings restores and enhances sway bar effectiveness, delivering handling improvements comparable to installing a larger-diameter bar. Proper lubrication with the included Super Grease at installation is recommended to ensure quiet, squeak-free operation.
