Sway Bar Set - front and rear


Progress anti-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 Anti-sway bars replace skinny OEM bars and rubber bushings with larger diameter (stiffer) alloy steel bars and polyurethane bushings. More roll stiffness means less body "lean", and the tires stay flatter on the pavement (larger contact patches). The result is more grip and added driver control!

-Less body roll means more traction, faster cornering speeds, and increased driver confidence.
-Polyurethane bushings produce crisp response on turn-in.

Progress Anti-sway bars are cold-formed in-house using our custom-built precision bending equipment. Both laser-cut and CNC bar ends are MIG welded in place using a precise fixture for an exact fit.

NOTE: This Sway bar system is designed for use with the cast aluminum OEM end links. The 'composite' type OEM links are NOT acceptable, and must be replaced.

NOTE: We offer an adjustable Teflon-lined spherical bearing end-link upgrade. Our PN #65.0480. This is an upgrade for aggressive track day and autocross use. The adjustable-length feature is useful for corner-balancing and pre-loading the bars for specific chassis setup requirements.
