Improve handling and add adjustability with easy installation too!
Construction -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 out bar better precision, higher quality and a fail free design.
Adjustibility - PERRIN Performance sway bars incorporate multiple endlink mounting holes which allow you or your installer to custom tailor your driving experience. PERRIN sway bars increase stiffness by a minimum of 100% overstock. Adjusting the endlink mounting position can increase that stiffness to as much at 400% over stock.
Bushings - 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.
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.
Wikipedia - A sway bar is an automobile suspension device. It connects opposite (left/right) wheels together through short lever arms linked by a torsion spring. A sway bar increases the suspension's roll stiffness—its resistance to roll in turns, independent of its spring rate in the vertical direction.
