The Kelderman 4-Link 8-10″ Air Suspension lift kit is designed for all 2013 and newer Ram 3500 trucks with a factory radius arm suspension, as well as the front of all 2014 and newer Ram 2500/3500 4×4 trucks. This kit raises the ride height of your truck by 8-10″ to allow you to run up to 40″ tires. With optional air controls, the kit can lower from its 8-10″ ride height down to a modest 4″ lift to make getting in and out, hooking up to a trailer, or fitting underneath your 8′ tall garage door much easier. Looking for maximum clearance or want to show off just how capable your 8-10″ air suspension is? Push a button and this kit raises up to a towering 14″ lift! These 4-Link Air Suspension lift kits for your Ram truck completely remove the factory coil springs up front and replace them with upper and lower bag plates and an industrial-strength airbag right into the factory spring bucket. This kit comes with everything you need to get the front end of your Ram up in the air including crossmember, upper and lower trailing arms, upper and lower bag mounts, sway bar drop bracket, lower shock mounts, track bar drop bracket, adjustable track bar, dual steering stabilizer bracket, drop pitman arm, indexing rings and industrial strength air bags. Fox shock packages are available for front and rear kits. Air control systems are also available.
