On my 8-luggers I crank the torsion bars. I have to run shocks for 2" lift. I do nothing to the rear because the rears sit as high as stock older trucks. It's the fronts that sit low for a 4wd. Blocks in the rear give nothing for load capacity. Add-a-leafs don't always give the claimed lift and only add little if any noticeable capacity. These rear springs are really long in the name of better comfort, which nets more sag sooner with use. On my '92 K3500 steady worker I added Air Lift auxiliary bags to gain adjustable height (I set where I wanted and left alone) and a true 1500# added capacity. The truck consistently weighed out of scrap yards at around 8,000#. She had a saggy butt after a couple hundred thousand miles. I did a lot of towing and it began to look like it couldn't handle what it easily was hauling. Here are pictures of it hauling a fairly heavy truck on a fairly heavy trailer, no bags at around 200k, and one virtually empty (exc heavy steel cap/racks/tools in bins and bed) w/bags at over 300k on untouched springs. Tires are 255/85-16
