Lowering a truck looks great, but it can leave you short on suspension travel and haul strength. SlamAir air springs add up to 2,000 lbs of load-leveling capacity so your ride stays level when the bed is loaded or the trailer tongue adds weight. They help keep steering and brake performance consistent, preserve headlight aim, and prevent uneven tire wear even when you’re running a heavy load.
Lowered suspensions hit their limits fast over bumps and dips. With SlamAir, you can dial in air pressure from 5 psi to 100 psi to prevent bottoming out and keep a smoother ride. Add air to firm things up under load or drop pressure for comfort when you’re cruising empty. Each spring can be inflated separately for side-to-side leveling when your setup isn’t perfectly balanced.
Getting the stance right is simple with the included manual inflation valves that mount on the bumper or wherever you want easy access. A few quick shots of air let you level front to rear or correct a lean from an uneven load. For more convenience down the road, you can add a compressor system with in-cab gauges (sold separately) to monitor and automatically adjust pressure.
SlamAir mounts between the frame and leaf springs with included brackets, fittings, tubing, and hardware. It reinforces your OEM suspension without changing your drop so you keep the lowered look while gaining real suspension support. The setup reduces sway and helps prevent the harsh bottoming that comes with hauling or towing on weakened suspension components—all backed by a limited lifetime warranty with no mileage restrictions.

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
