Any upgrade to the sway bars are nearly lost if you choose to reuse the OEM unit endlinks. This connection between the sway bar and the control arm is crucial for proper operation. Some Subaru models even have plastic (yes plastic) to make this connection. Perrin replaces any and all with 6061 billet aluminum and spherical bearings. By utilizing aluminum the sway bar can respond in a far more linear fashion to cornering forces, while the spherical bearings allow additional articulation under hard cornering. The combination forces and allows the tires to remain in contact with the road. Simple to install and maintenance free. All include instructions and hardware.
