I didn't see a great deal of info on lifting a 2nd gen Avalanche using H2 springs so I thought I would post my experience. I recently bought a 2010 4wd, non-Z71 and wanted to clear 285/70R17s. The front I did with a 2" strut and upper control arm and there was just a tiny bit of rubbing. The rear cleared fine stock but was now lower than the front, especially with our roof top tent on the bed rack.
For the rear I bought Chassis Tech H2 springs, 261947048051. I finally got around to installing them this weekend and initially the rear went up 3.75". The next day we went on a 6 hour off-road trip with the truck and that settled them down to a 2.75" lift. The ride without the tent is really good with the Fox 2.0 shocks. When I had both sets of springs out, the H2 springs are noticeably thicker and have progressive wind to them.
Plans for now are to put the tent back on and see how much it squats the rear and then level it. I bought a set of 2019 18" take offs for street use and I want to get some 275/70R18 tires for those and have just one set of wheels. I also have a some aluminum diamond plate that I want to cut up and make a new front skid plate and a belly plate to cover that big gas tank. I found an aftermarket Ford bumper that I think I can modify to fit on the Avalanche by cutting the plastic bumper....will have to see how that might look.
