Traxda 2"-3" adjustable torsion key lift includes a pair of torsion keys, shock relocation brackets, bolts, nuts and washers with full color instructions and complete alignment specs. 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. The key positioning has been changed to an optimized mathematically engineered and road tested design. 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.
