Lowering a truck looks great, but it can cut into suspension travel and load capacity. SlamAir air helper springs add up to 2,000 lbs of suspension support, restoring that missing strength so you can haul or tow with confidence. They help keep the truck level under heavy loads, improve steering and braking response, and prevent bottoming out when the bed is carrying weight. Even with a lowered frame, you get the solid, stable ride your factory suspension used to deliver.
No two loads are the same, and SlamAir lets you tune your suspension to match. Each spring can be inflated independently from 5 to 100 psi using manual inflation valves, giving you control over front-to-rear and side-to-side leveling. Whether it’s evening out an off-center load or maintaining normal ride height when towing, you can fine-tune your setup for comfort and control on every drive.
Heavy loads put extra stress on factory components, especially on a lowered setup. These air springs take that strain off your OEM suspension, spreading weight evenly across the axle to minimize sway and reduce uneven tire wear. By keeping your vehicle level, they also help maintain proper headlight aim—important for safe nighttime driving with cargo or trailers.
Everything needed for setup comes in the box—air springs, mounting brackets, tubing, fittings, valves, and hardware. The springs install between the frame and leaf springs using straightforward mounting points, while manual inflation valves typically mount at the bumper for easy access. It’s a clean install that adds real function without complicated modifications.

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
