Take your vehicles handling to the next level with the PERRIN 22mm Adjustable Front Sway Bar. Upgrading your sway bar is the easiest way to improve vehicle handing. Sway bars increase roll resistance and modify vehicle balance. In general, adding a larger rear sway bar increases over steer, and adding a larger front sway bar increases under steer. Upgrade both front and rear sway bars to reduce body roll and tune vehicle balance to your preference.

22mm or 25mm

PERRIN Performance sway bars come in two different sizes. 22mm and 25mm. Driving enthusiast will enjoy the feel of a 22mm bar while true racers will like the rigidity of the 25mm.


PERRIN Performance sway bars incorporate multiple end link mounting holes which allow the installer to custom tailor your driving experience. This PERRIN sway bar increase stiffness by a minimum of 50% overstock. Adjusting the end link mounting position on this sway bar can increase that stiffness to as much at 215% over stock.

Centering Rings

Perrin Performance sway bars feature centering rings that prevent sway bar movement in hard cornering. This keeps your sway bar centered and ready for the next corner.


PERRIN sway bars are CNC precision bent from solid 4130 chromoly steel. The entire bar is heavily powder coated to fight corrosion and give it a great red finish. We laser cut and MIG weld our bar ends for precise placement and superior strength. This type of bar end will never fail and offer you a lifetime of superior handling.


All PERRIN sway bars include custom polyurethane bushings for a crisp response and better turn in. Special spiral cut pockets carved into the bushing surface extends the interval between re-greasing.
