Prothane 8-1132-BL Black 23mm Rear Sway Bar Bushing Kit

The Prothane 8-1132-BL is a black polyurethane rear stabilizer bar bushing kit designed as a direct, performance-oriented replacement for the factory rubber sway bar bushings. Engineered from premium-grade polyurethane, these bushings deliver significantly improved rigidity and responsiveness compared to soft OEM rubber, reducing body roll and improving overall handling feel.

Each bushing features a grooved bore specifically designed to retain Prothane's proprietary super grease, ensuring smooth, quiet operation throughout the service life of the bushing. The precision-machined design guarantees a proper fit for a hassle-free installation. This kit is designed for a 23mm rear sway bar and is sold as a pair.
