Box 1 of MaxTrac’s 7-inch lift kit for 2007–2016 GM K1500 4WD contains the front steering knuckles cast from ductile steel and finished with an e-coating. This component box is one of three required to complete the full lift kit; all three boxes must be ordered to assemble the complete system. The knuckles are supplied to provide the steering geometry changes needed for the taller suspension setup.
