airmaxxx Tow Assist Air Over Load Kit w/ Compressor, Tank & Gauge Fits 2001-2010 Silverado/Sierra 8 Lug 2500/3500

Heavy Hauling Support with Onboard Air

Add confidence to every tow with the airmaxxx Tow Assist Rear Load Leveler Kit with Compressor, Tank & Gauge, built for 2001–2010 Chevy Silverado and GMC Sierra 2500/3500 8-lug trucks. This complete rear air spring system provides up to 5,000 lbs of load leveling capacity to reduce squat, sway, and bottoming out while hauling or towing.

The included AM400 pewter compressor, 3-gallon steel tank, and single-needle gauge give you onboard control, making it easy to inflate or deflate the air springs whenever needed — just like adding air to a tire. With bolt-on brackets that replace your factory bump stops, installation requires no drilling or welding.
