The Superlift Replacement Steering Stabilizer kit includes a single Superlift SS cylinder, plus all required mounting hardware. The cylinder's seamless, extruded monotube body contains a patented piston design, and a high-pressure gas charge to quickly dissipate heat and virtually eliminate fade. Cylinder valving is tailored to meet the demands of heavier tires/wheels and aggressive terrain. The cylinder features a brushed, silver Zinc finish. A steering stabilizer is basically a shock absorber for your steering system. It allows unrestricted gradual movement but resists sudden shock. Stabilizers also combat other forces that induce tire shimmy, such as larger/heavier tires and wheels and slack in your suspension and steering systems that occur from normal wear. Most vehicles are factory equipped with a stabilizer, yet like most factory shock absorbers, they are barely adequate and have a limited service life. Look for signs of oil leakage where the shaft meets the cylinder body.
