I just picked up a 15' Tahoe LT with the HD tow package and Z85 rear leveling air suspension. The shocks are shot all around, so I need to replace them. I had the Fox coilovers and rears on my 15' Silverado and they were great. Can i use the same setup on this truck without issue? What do people usually do for rear shock replacement with the air shocks that don't want to pay top $$$ for OEM stuff? Thanks in advance.
