2015-2019 GMC Sierra 3500HD Air Suspension Kits

Air suspension kits engineered for the 2015-2019 GMC Sierra 3500HD, covering both single-rear-wheel and dually configurations. Stocking Air Lift LoadLifter 5000 and Firestone Ride-Rite kits rated up to 5,000 lbs of leveling capacity, with compressor-system options for on-board inflation.

Will these bags let me tow and haul heavier without squat? Yes. The bags mount inside the factory rear coils or leaf pack and inflate from 5 to 100 PSI to level the truck under gooseneck, fifth-wheel, or bed loads without changing unloaded ride height.

Verified fitment for your Sierra 3500HD, no guesswork.
