2015-18 Subaru STI Front Sway Bar
Sway-A-Way’s 2015-2018 Subaru STI front sway bar is designed to replace the factory sway bar with an adjustable larger diameter sway bar. Stock, the 2015+ Subaru STI both come equipped with a 24mm front sway bar. Sway-A-Way’s PN: 1908 is a 25.4mm replacement with two holes of adjustment. Hole one offers a 35% increase in stiffness, with the second hole offering a 17% increase. This small but tangible increase in stiffness results in less body roll for better overall handling and sharper steering response.

CNC Bent to Factory Profile
Sway-A-Way uses in-house 3D scanning equipment and a CNC bender to closely 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. These bushings & grease are sourced directly from Energy Suspension, the leader in performance polyurethane products.
