An air ride system depends on valves. There is nothing more problematic and annoying than leaking valves. Leaking dump valves and leaking lift valves can transform a perfectly capable bagged truck into an un-drivable pile in the driveway, or worse, on the side of some road. Commuter Status had seen many valves come and go over the four years, ranging from 3/8" to ¾". At one point, two different size lift valves were used up front, making the ride "level enough."
Regarding valves, I couldn't decide if I wanted fast or slow valves. Because I wanted it all, I decided I could have exactly this by using Slam Specialties Digital Stealth Valves (DSV). One setting on the controller utilized 3/4" GC valves, while another setting made use of a slow and controllable Stealth Mode. This was perfect, since I wanted to have super fast suspension, but also wanted to be able to adjust safely on the freeway or in proximity of police. It seemed logical that any commuter should have the option to be mellow or crazy with the flip of a switch.
These dual-functioning valves created a hefty combination of hardware per corner of the truck, which needed a sturdy mounting surface. The truck's frame rails were designated as the location to mount the valves. Home-made brackets were welded to the frame, and the valves were then bolted to these brackets. This allowed for sturdy mounting as well as easy accessibility and removal of the valves for maintenance.
