Prothane 12-1102-BL Front Sway Bar Bushing Kit 15/16in Black Polyurethane

The Prothane 12-1102-BL is a front stabilizer bar bushing kit crafted from high-performance black polyurethane, designed as a direct upgrade over factory rubber bushings. Sized at 15/16 inch (approximately 23.8mm) bore diameter, these bushings deliver a firmer, more precise interface between the sway bar and chassis to reduce body roll and improve cornering response.

Unlike OEM rubber bushings that deteriorate over time — warping, cracking, and losing their grip — Prothane polyurethane maintains its shape and firmness throughout its service life. Each bushing features a grooved bore interior engineered to retain Prothane's Super Grease, ensuring smooth, quiet operation without squeaking. The black formulation also incorporates a small amount of graphite into the polyurethane compound, offering additional protection against noise.

Key Features:

• High-durometer black polyurethane construction — significantly firmer than OEM rubber
• Grooved bore design retains Super Grease for quiet, long-lasting performance
• 15/16 inch (approx. 23.8mm) bore diameter for precise sway bar fitment
• Resists degradation from road grime, oils, and weathering
• Made in the USA
• Backed by Prothane's Lifetime Warranty against defects in materials and workmanship
• Includes Super Grease packet for installation

Upgrading to Prothane polyurethane sway bar bushings delivers handling improvements comparable to installing a larger-diameter sway bar — at a fraction of the cost. These bushings keep the stabilizer bar firmly located, maximizing the bar's effectiveness in controlling body roll and maintaining tire contact during cornering.
