This 6.5" system will give you an offroad worthy SUV that you can still use as a daily driver. Custom valved replacement struts are included to properly handle the increased weight of the larger tires & wheels. The massive 1 piece main crossmembers are made from 1/4" 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 6" system is built to perform!
