The rear suspension also includes a custom cantilever airbag setup for when Simmons needs to haul heavy cargo or tow a heavy trailer with the truck. “Building a rig that is capable off-road and able to carry a load and drive down the highway isn’t that easy. I really did some head scratching trying to figure out how to keep some load capacity and let the suspension flex, so I built the cantilever airbag setup that allows nearly 12 inches of suspension travel to be controlled by one four-inch airbag (per side). I didn’t really want to use a big, expensive, 12-inch airbag in a ‘one-to-one’ configuration to handle the load when need be, Brown says.” The Schrader valves for both airbags are located in the driver-side compartment on the flatbed.
