Prothane 7-1142 Rear Sway Bar Bushing Kit 19mm for Corvette 1984-1996

The Prothane 7-1142 is a polyurethane rear stabilizer bar bushing kit designed for 1984–1996 Chevrolet Corvette applications with a 19mm rear sway bar. Replacing the factory rubber bushings with these firm polyurethane units is one of the most cost-effective ways to restore and improve the handling performance of your Corvette's suspension system.

OEM rubber stabilizer bar bushings deteriorate over time, becoming soft and compliant in ways that allow excessive body roll and reduce steering precision. Prothane's polyurethane compound resists compression, heat, oil, and ozone degradation far better than rubber, maintaining consistent performance over the life of the part.

Key Features:

• Manufactured from Prothane's proprietary polyurethane compound for superior durability over OEM rubber
• Grooved bore design retains Prothane Super Grease for smooth, quiet, squeak-free operation
• Firm bushing material reduces body roll and improves handling response
• Fits 19mm rear stabilizer bars on 1984–1996 Corvette
• Also compatible with larger-diameter high-performance aftermarket sway bars
• Resistant to oil, ozone, and heat — will not sag or crack like rubber over time
• Direct bolt-on replacement — no permanent modifications required

Each kit includes the bushings and necessary hardware for a straightforward installation. Prothane Super Grease is recommended at installation to ensure quiet, long-lasting performance. Prothane polyurethane suspension components are a trusted upgrade for enthusiasts looking to sharpen handling without a full suspension overhaul.
