Once we removed the Trailer Products front fiberglass clip, we revealed beautiful symmetry of high-quality fabrication all done by BMS. BMS is also responsible for the suspension creation aside from the rear trailing arms. The upper control arms are what is known as J-arms because of their shape. They allow fluid travel movement and clearance for large shocks. The front suspension pushes 20 inches of travel using billet upper J-arms and lower center-mounted control arms made of 4130 chrome-moly.
