One knob makes it simple to soften the ride for cruising or firm it up for maximum handling response. RIDE HEIGHT FLEXIBILITY This system allows you to adjust ride height from factory stock height down to 2” lower, giving you flexibility to fine-tune stance, handling balance, and wheel/tire clearance while maintaining proper geometry. EASY BOLT-IN INSTALLATION No cutting or welding required.
