We made design changes to the axle mounts so the same kit will now fit models from 2010 to current 2500HD or 3500HD single or dual rear wheel trucks. This kit will not fit 3500HD chassis cabs. We have a specific kit for them on the manufacturer page.

The ASAM works in tandem with the factory suspension to provide vertical lift controlled by you with air pressure. Any air source from a bike pump to a wireless air system can be utilized. Please view our "AIR SYSTEMS" page for additional information.

Since introduction, this rugged kit has provided numerous owners support and confidence while towing. Whatever you do with your truck, this kit will perform the task safely & effectively. Please review our "SAFETY" page.

Our design philosophy is to build them tough with quality components that perform without fail and stand behind every product 100%. Please view our "GENERAL INFO" page for additional information.
