CNC Bent to Factory Profile

Sway-A-Way uses in-house 3D scanning equipment and a CNC bender to precisely match the factory sway bar profile. This process allows for Sway-A-Way to manufacturer highly accurate sway bars designed to easily bolt-in.

Precision Forged Ends

Through processes mastered over the last 30+ years, Sway-A-Way uses induction heating, presses, CNC plasma cutting, and custom tooling to craft forged ends. This combination of CNC bending and forged ends results in a sway bar that is both strong, accurate and ready for the track.

Powder Coated for Corrosion Resistance

Sway-A-Way sway bars are sent locally to be sand-blasted and powder coated a bright red finish for lasting corrosion resistance.

Polyurethane Bushings & Grease

Included with every sway bar are two polyurethane bushings cast specifically for the stock bushing bracket and Energy Suspension Formula 5 Polyurethane Grease. Sway-A-Way’s bushings & grease are sourced directly from Energy Suspension, the leader in performance polyurethane products.

This kit reduces front and rear body roll, improves overall handling and grip, sharpens your steering response and provides a more neutral/oversteer balance.
