79-04 Mustang Front Sway Bar Bushings 27mm

The PROTHANE 79-04 Mustang Front Sway Bar Bushings 27mm (part number 6-1135) are high-performance polyurethane replacements designed for Ford Mustangs produced between 1979 and 2004. These non-greasable bushings upgrade the factory rubber components on your sway bar, delivering improved handling response and consistency across a wide range of driving conditions. Supplied as a matched pair, they address one of the most common wear items on classic and modern Mustang platforms.

The 27mm bar diameter specification matches the OEM sway bar dimensions for these model years, ensuring direct fitment without modification. Polyurethane construction provides greater durability and resistance to degradation compared to stock rubber bushings, which typically harden and crack after years of exposure to heat, UV, and flexing. The bright red color aids visibility during installation and makes future maintenance straightforward. Since these bushings are non-greasable, they require no ongoing lubrication—eliminating the maintenance burden of traditional grease-type designs while maintaining consistent damping characteristics over the life of the product.

This upgrade is ideal for Mustang owners seeking sharper cornering feel and reduced body roll without investing in complete suspension overhauls. Whether you're driving a fox-body model, third-generation, or earlier classic Mustang, worn sway bar bushings degrade chassis stability and steering response. Replacing them with these PROTHANE polyurethane units restores predictable handling and is one of the most cost-effective suspension improvements available for the platform. Installation is straightforward for anyone with basic mechanical skills and an appropriate sway bar removal tool.
