Here are the rear air bags from Air Ride. I told them I was building a Pro-Street rear suspension and wanted to run air bags in place of Coilovers, they hooked me up. These bags have about 9 1/2 inches of travel, so I should be able to lift my truck up to ride over the speed bumps, put it in the middle for driving, and slam it in the weeds for cruising and showing. In place of an air tank, compressor etc right now, I got their manual inflation kit. The kit comes with lines, a T-fitting and an air chuck inflation valve, like you'd have on air shocks. Using my air compressor, I should be able to lower and lift the suspension during buildup. Click here for a close-up photo.
