I got the blocks from suspensionmaxx.com I saw the ad in the tdr calendar a while ago, yr or two ago, my truck was down and out for a few weeks, and figured I'd put them on, got the links on it yrs ago and liked them ok, most leveling kits ive seen are cheesy abs plastic, liked these because their billet aluminum, cant remember how much I paid, think there was a promotional offer going on at the time or something, cant see it being much more than $150. Only thing with doing a level is that you open up a can of worms with getting the axle off center, got to get an adjustable track bar, then the rear will sag like an overloaded half ton with a heavy load in the bed unless you beef up the spring pack or put bags in the rear
