Prothane 7-1148 Polyurethane Front Sway Bar Bushing Kit 26mm 1984-1987 Corvette

The Prothane 7-1148 is a front stabilizer bar bushing kit designed for 1984–1987 Chevrolet Corvettes equipped with a 26mm front sway bar. Prothane's polyurethane bushings are a direct upgrade over the factory rubber units, delivering tighter handling response and improved anti-roll bar effectiveness without sacrificing ride quality.

Stock OEM rubber stabilizer bar bushings tend to deteriorate over time, becoming soft and compliant in ways that allow the sway bar to shift under load — reducing its effectiveness and contributing to excessive body roll. Prothane's firm polyurethane compound corrects this by maintaining consistent geometry and bar contact through cornering forces.

Key Features:

• Fits 26mm front stabilizer bars on 1984–1987 Chevrolet Corvette
• Made from Prothane's high-durometer polyurethane compound for long-lasting performance
• Grooved bore design retains Prothane super grease for quiet, squeak-free operation
• Resists oil, road chemicals, and ozone degradation better than OEM rubber
• Reduces body roll and improves steering feel and cornering response
• Direct replacement for factory stabilizer bar bushings — no modifications required
• Also compatible with larger-diameter high-performance aftermarket sway bars

Each kit includes the polyurethane bushings and Prothane's specially formulated super grease to ensure proper lubrication and quiet performance from day one. A straightforward upgrade for any Corvette owner looking to sharpen handling without a full suspension overhaul.
