Look at the Zone Off Road BLs for pickups. They can be used on the GMT800 SUV’s as well. I have a Zone 1.5” on my Sierra. Been on there since 2009ish. They are good kits. At the 1.5” mark the only thing I had to do was relocate bumpers(front is a must/rear preference), relocate the parking brake cable, and relocate the fan shroud. The OPs being a 2006, if he won’t have to worry about the fan shroud since it has e fans from the factory. I’d recommend the 1.5” BL and GM White Keys Combo. The white keys will give a nice level stance and of course the 1.5” BL lifts the whole body to add for extra tire clearance. Minimal front end stress to ultimately net 2.5-3.5” front total liftDoes anyone make a 1 to 1.5 inch body lift For A 2003 suburban 4wd. I can fine 3 inch all day long but I am not looking for that.
