This 4.5 inch system will give you an offroad worthy truck that you can still use as a daily driver. The massive 1 piece main crossmembers are made from 1/4 inch thick steel and built to handle anything. In addition to a heavy duty differential skid plate that locks the two crossmembers together an additional strut bar is included on the passenger side to ensure a solid sub-frame. The CNC machined ductile iron steering knuckles ensure proper steering geometry as well as reduce installation time compared to a drop bracket system. Combine all of these factors and the Zone 4.5 inch system is built to perform!
