@915_Tahoe - question if u don’t mind. My 05 Yukon XL 4wd has part number 15115209 springs and appear to be original. The previous owner removed a 3 inch lift and put non nivomat shocks. I have zw7 but not g65 rpo codes. Are the springs on it the heavy duty or z71 springs? Looking to replace and want to get correct ones. Was looking at Acdelco 45H2164
