Progress Technology 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 Sway Bars replace skinny OEM bars and rubber bushings with larger diameter alloy steel bars and polyurethane bushigs. 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.

The two adjustment mounting holes provide 3 levels of stiffness:

• stiff = both ends at forward holes
• soft = both ends at rear holes
• medium = one at forward and one at rear hole

Progress Sway Bars are cold-formed in-house using our precision bending equipment. Both laser-cut and CNC bar ends are MIG welded in place using a precise fixture for an exact fit. Larger than factory sway bars are a great handling upgrade for the moeny! A stiffer sway bar works to further reduce body roll by tying together the right and left sides of the suspension. This essentially lends more wheel rate from the side that's in droop to the side that's being compressed.

Sway bars often go by a few different terms (some more correct then others). Some other names you might hear are: anti-roll bars, roll bars, or anti-sway bars. Well engineered sway bars control body roll and are not the same as strut bars or other chassis reinforcement hardware! Strut bars and chassis stiffeners do not effect body "lean".
