Product Details

Improve handling and add adjustability with easy installation too!

PERRIN sway bars are made from solid steel using precision bending equipment. The entire bar is heavily powder coated to fight corrosion and give it that great red finish. We laser cut and MIG weld our bar ends for precise placement. This type of bar end will never fail and gives us greater precision over competitors. Utilizing this style of manufacturing process gives our bar better precision, higher quality and a fail free design.

16mm, 19mm, 22mm or 25mm
PERRIN Performance sway bars come in four different sizes; 16mm, 19mm, 22mm and 25mm. We recommend the 16mm sway bar upgrade for drivers wanting a little sportier handling on stock or comparable tires. Driving enthusiast will enjoy the feel of a larger rear sway bar as it reduces under steer and in some cases adds over steer for drifting enthusiasts. When upgrading tires to grippier compounds and wider widths the larger sizes may be just what you are looking for.

PERRIN Performance sway bars incorporate multiple endlink mounting holes which allow the installer to custom tailor your driving experience.

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.

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