The Superlift dual steering stabilizer kit includes two Superide cylinders and the hardware to mount them in-line. Superide stabilizer cylinders feature increased oil capacity to keep the operating temperature lower resulting in less fade, plus valving tailored for the demands of heavier tires and wheels and aggressive terrain. Steering stabilizers are basically a shock for your steering system to combat tire shimmy and suspension slack that may result with the addition of a suspension lift and larger tires. The Superide cylinders are far superior in performance compared to the factory cylinders and will make a noticeable difference in ride quality. Shock boots are sold separately.
