This new kit represents a revolution for Air Lift Performance by utilizing an industry first: a 30-way adjustable, monotube shock as the foundation on which to build the finest air suspension. These high-performance shocks dissipate heat faster than twin tube shocks, and provide more consistent damping during hard driving or bumpy road conditions. Another new feature is the adjustable lower perches that allow ride height to be changed—independently from pressure—further increasing the flexibility of these kits. You can dial in the preferred pressure,ride height, and damping combination for fantastic ride or maximum handling, and even adjust for different vehicle weight combinations. They look great too, with bright red anodized accents and shiny black powder coating to protect them for years to come. No one else in the world of air suspension has all these features!
