Handling

PERRIN Swaybars are designed to improve handling by reducing body roll and increasing cornering performance. By reducing body roll, the lateral loads on the tires become more evenly distributed, resulting in enhanced cornering grip and overall performance improvements.

Size

PERRIN Swaybars come in three sizes; 16mm, 22mm, and 25mm. Driving enthusiasts will enjoy the feel of a 16mm bar while the more race-oriented drivers will like the rigidity of the 22mm and 25mm options.

Adjustability

PERRIN Swaybars incorporate multiple endlink mounting holes which allow for a customizable experience. The adjustability allows you to fine-tune your handling, whether it be track or street oriented.

Centering Rings

PERRIN Swaybars feature centering rings that prevent swaybar movement in hard cornering. This keeps your swaybar centered and ready for the next corner.

Bushings

All PERRIN Swaybars 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. All our bushings include a grease packet for your swaybar installation.

What is a Swaybar and How Does It Work

Wikipedia defines a swaybar as "...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."
