DSC’s proprietary and patented Air-Chassis® product line offers multiple, yet simple and unique ways to economically and efficiently modify almost any major OEM’s chassis platform into a state-of-the-art air suspended transit bus, commercial truck, ambulance, etc., that provides improved vehicle stability, handling, and ride. Provides on-demand (from the vehicle’s normal ride height) options to lower vehicle load floor for easier loading and unloading of passengers and products, and a softer more comfortable vehicle ride.
Special Feature: When loading/unloading, Air-Chassis automatically self-levels… regardless of road surface irregularities.
Whether you are looking for a better, safer, and easier way to transport people – including complete ADA compliancy – or, you are searching for a vehicle that can transport products faster, with a better and easier way to load and unload cargo – you should learn how DSC’s Air-Chassis can provide what you are wanting and needing in your next vehicle purchase.
DSC works directly with major body-builders who up-fit Air-Chassis into completed transit shuttle buses, commercial trucks, and ambulances – DSC will interface closely with your selected up-fitter every step-of-the-way to complete your total vehicle build.
