Becareful with the torson keys with the lift kit. Years ago we tried new torson keys on my 6" lifted truck, adjusted them up and drove the truck for a test drive. When I got back the front CV axle boots had pulled loose because the CV joints were over extended. Also I'm sure your lift kit came with a 1"-11/2" add-a-leaf and a 4" lift block for the rear and not a 5" block.
