Leacree Air suspension system essentially replace a vehicle's coil spring with air springs. The air springs are simply tough rubber and plastic bags inflated to a certain pressure and height to mimic the coil springs. But the similarities end there. By adding in an on-board air compressor, sensors and electronic controls, today's air suspension systems provide several advantages over all-metal, conventional springs, including near-instant tuning, and the ability to adapt handing to different situations and varying load capability.
Air suspension can lower a car to improve its street credibility, even out a heavy payload, or simply improve the ride of a vintage Detroit metal street monster.
