At the 2012 SEMA Show, we stopped by the Air Lift booth to chat with their Western Regional Sales Manager, Matt Dougherty. The 67-year old brand roots are in Nascar, but has moved their attention away from the track and onto the streets. In their booth, they proudly displayed the new LoadLifter 5000. This heavy-duty spring fits many three-quarter ton and 1 ton pickups. It has an impressive 5000lb load-leveling capacity.
