Prothane 6-1133 Front Sway Bar Bushing Kit 1-3/8" for Ford Mustang

The Prothane 6-1133 is a polyurethane front stabilizer bar bushing kit designed as a direct replacement for the factory rubber bushings on 1979–2004 Ford Mustang models equipped with a 1-3/8" diameter sway bar. Upgrading to Prothane's polyurethane construction delivers a noticeably firmer, more controlled suspension feel by eliminating the flex and deformation common in OEM rubber bushings.

Key Features:

• Manufactured from Prothane's durable polyurethane compound for superior longevity over stock rubber
• Designed for a 1-3/8" (1.375") diameter stabilizer bar — fits both OEM and compatible aftermarket sway bars
• Grooved inner bore retains Prothane Super Grease for smooth, squeak-free operation
• Reduces body roll and improves cornering stability by maximizing sway bar effectiveness
• Also compatible with larger-diameter high-performance aftermarket sway bars of matching size
• Direct bolt-on replacement — no modifications required
• Available in Prothane's classic red polyurethane finish

Prothane polyurethane bushings are engineered to outperform OEM rubber in both street and performance driving applications. The 6-1133 kit includes all bushings and hardware needed for a complete installation, making it an ideal upgrade for Mustang owners looking to sharpen handling response without sacrificing ride quality.
