A lowered truck looks great but loses suspension travel and load capacity. The Air Lift SlamAir Air Helper Springs add up to 2,000 lbs of load-leveling support between the frame and leaf springs, keeping your rear end from sagging when hauling gear or towing. That extra support helps your truck stay level for better steering response, braking control, and safe headlight aim even with heavy weight in the back.
Every load is different, so you need control over how your suspension feels. With SlamAir, you can manually adjust each air spring from 10 psi to 100 psi to dial in the right firmness for your setup. Inflate both springs evenly for front-to-rear leveling or adjust them independently to balance off-center loads side to side. Whether you’re running empty or hauling a full bed of tools, it’s easy to get the ride feel and stance you want.
Lowering a truck often means running out of suspension travel under load. The SlamAir system is built specifically for trucks dropped 2"–6", with the right spring height range to prevent bottoming out without raising ride height. By sharing the load with your factory leaf springs, it reduces the strain on OEM components and keeps your suspension geometry working as it should even with flipped axles or notched frames.
Everything needed for installation is included—air springs, brackets, air line tubing, inflation valves, fittings, and hardware. Manual valves mount cleanly on the bumper or wherever access is convenient. You can even add an onboard compressor system (sold separately) if you want automatic pressure control later. It’s a straightforward setup that makes it easy to get proper leveling support without sacrificing time in the garage.

1 year update , still working great and with my tuck 22s on there was almost enough clearance but I did grind a little off the outer lip of the upper bag mounts to clear the rim with extra room when the truck was on the loft and the rear hanging but with the truck on its own weight there wasnt any clearance issues and I only took a little off to make sure there was extra room it wasnt 100 necessary
