Adjustable Ride Height

This air suspension lift kit utilizes high-quality Firestone airbags along with upper and lower air bag plates to get your truck to a proper height without diminishing ride quality or handling. Ride height is centered right at 4-6", however with available air control systems you can choose to adjust compression and ride height from as low as one inch to a gargantuan eight inches! Kelderman offers a variety of controller options to allow you to adjust the ride height from the comfort of the driver's seat, all of which are available by calling Stage 3 at 623-434-5277. If you decide against a control system for now, you can still adjust the ride height manually with just about any compressor like a regular tire. This front air suspension lift kit delivers a softer, more supple ride than traditional suspension systems without sacrificing towing capacity.
