Prothane 7-1102 GM Small Block Sway Bar Bushing 1-1/4" Polyurethane 1973-1991

Upgrade your suspension performance with the Prothane 7-1102 polyurethane stabilizer bar bushing, designed as a direct replacement for the factory rubber sway bar bushings on 1973–1991 GM applications. These bushings fit a 1-1/4" diameter stabilizer bar and are engineered to restore and enhance the effectiveness of your OEM anti-roll bar setup.

Stock rubber bushings deteriorate over time, becoming soft and compliant, which allows excess body roll and imprecise handling. Prothane's polyurethane compound is significantly firmer than OEM rubber, resulting in tighter suspension response, reduced body roll, and improved cornering stability.

Key Features:

• Fits 1-1/4" diameter OEM and performance sway bars
• Grooved bore design retains Prothane super grease for quiet, long-lasting operation
• Polyurethane construction for superior durability over factory rubber
• Resists oil, ozone, and weathering better than OEM rubber bushings
• Direct OEM replacement — no drilling or modification required
• Also compatible with larger diameter high-performance aftermarket sway bars (where applicable)
• Made in the USA

Prothane polyurethane bushings are a proven upgrade for enthusiasts seeking improved handling without sacrificing ride comfort. Each bushing is pre-greased and ready to install, making this a straightforward suspension refresh for a wide range of 1973–1991 GM vehicles.
