Progress Tech sway bars dramatically improve handling. How? They minimize the traction-robbing body "lean" that rolls part of the outside tires off the pavement. Our Sport-tuned Sway Bars replace smaller OEM sway bars and rubber bushings with larger diameter alloy steel bars and harder polyurethane bushings. Adding more "roll stiffness" means less body "lean" or "sway" and the tires remain flatter and better-connected to the pavement. The larger and more stable tire contact patches result in more grip, control and added driver confidence. Chassis tuning with larger and/or adjustable sway bars is a simple and effective method to improve chassis balance and minimize the excessive understeer (or plowing) so common in our modern vehicles. Progress Tech Sway Bars are cold-formed in-house using our precision CNC bending equipment. Both laser-cut and CNC-machined sway bar ends are MIG-welded in place using precise fixtures for an exact fit. All Progress Tech Sway Bars are developed and manufactured in-house and proudly made in the USA.
