I have installed an RCD lift on a 1/2 ton that year. You may want to get the instructions on how to install it, the frame has to be cut where the front diff mounts, and a plate welded in. You have to drill holes for the new torsion bar rear mount. Its not really that hard, but to put the stock stuff back is where the problem maybe if the mount was cut off. Other than that it is basically just bolt in stuff. The Duramax truck may have a heavier torsion bar than your gas engine truck. Be sure to keep the correct torsion bars with the right trucks.
