Carl's Unlimited 4 short-course truck is equipped with a single 3x16-inch King coilover at each front corner to obtain about 18 inches of front wheel travel. The 2WD truck the team runs is very similar, but we used their 4WD one here for our example. By comparison, the desert truck uses a 3x14-inch Fox coilover (closer to the pivot point) supplemented with a 4.3-inch triple-bypass shock and a nitrogen bumpstop to handle the really hard landings when they run out of the 24 inches of front travel. The Geiser-built truck also uses a front sway bar, which is not always a given on a Trophy Truck. Also, both trucks use full hydro steering boxes for directional duty.
