Sway Bar Bushing Set

The Energy Suspension Sway Bar Bushing Set (SKU ENE4-5201R) is a rear polyurethane and cadmium-plated steel upgrade designed for 2011–2014 Ford Mustangs with 22mm sway bars. This Hyper-Flex bushing kit replaces factory rubber components with high-durometer polyurethane, dramatically reducing bushing deflection during cornering and improving steering responsiveness. The red polyurethane construction and cadmium plating provide both visual distinction and extended corrosion resistance, making this a popular choice for enthusiasts seeking measurable suspension geometry improvements without replacing the entire sway bar assembly.

Polyurethane bushings maintain consistent load characteristics across a wider temperature range than rubber, which means handling characteristics remain predictable whether driving in cold start conditions or after sustained track sessions. The 22mm bar specification is critical—this dimension determines fitment and load rating for fifth-generation Mustang chassis. The kit format includes all necessary bushings and hardware for a complete rear sway bar installation, eliminating the need to source individual components. Installation typically requires removal of the rear sway bar, which most home mechanics can complete in under two hours with basic hand tools.

This bushing set is built for Mustang owners pursuing chassis dynamics improvements—autocross competitors, track drivers, and enthusiasts who prioritize cornering control and feedback. The polyurethane-to-steel construction provides the durability needed for repeated suspension articulation while eliminating the play and compliance that develop in degraded factory bushings. For S197 Mustang platform owners upgrading suspension geometry for performance driving, this rear sway bar bushing set represents a cost-effective, bolt-on stiffness upgrade with immediate real-world effect on handling precision.
