Prothane 7-1173-BL Front Sway Bar & End Link Bushing Kit 32mm Black

The Prothane 7-1173-BL is a complete front sway bar and end link bushing kit designed for the C4 Corvette. Engineered from high-performance polyurethane, these bushings are a direct upgrade over the factory rubber units, which are prone to warping, cracking, and losing their grip on the bar over time — all of which reduce sway bar effectiveness and compromise handling.

Prothane's polyurethane compound maintains a firm, consistent grip on the sway bar throughout its service life. This snug interface allows the sway bar to perform at its full potential, delivering handling improvements comparable to installing a larger diameter bar — without the added expense. The bushings feature grooved bores designed to retain Prothane's included Super Grease, ensuring quiet, squeak-free operation.
