Torsion keys by Traxda and front shock relocator brackets complete this package. These adjustable keys will not change the OEM ride quality. Lift can be installed with an OTC7249 Ball Joint Press and common hand tools. On some trucks you can fit 35" tires, 315/70 x 17, with stock off set style custom wheels. All Traxda torsion keys are CNC laser cut from Mill Certified (A+) steel. The tensile strength level of steel is twice as strong as it needs to be. The ends of the keys are precision drilled to allow for both the adjusting bolt and the installation tool. All keys are powder-coated with an "environmentally green-friendly" black finish.
