All Traxda torsion keys for the Chevy Silverado and GMC Sierra are CNC laser cut or the Chevy Silverado and GMC Sierra 1500HD or 2500HD 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 2.5" lift kit comes with shock brackets and is designed to use the stock GM shocks or stock length aftermarket replacements...no need to search for longer shocks! Also included is a 1" solid steel rear block kit. Front wheel travel is increased up to 3" and stock ground clearance is greatly improved.
