I’ve looked everywhere and I’m trying to figure out the stock block size on a 2015 3500HD 4x4 duramax Denali. Anyone have a pic? I bought a used one from a ford dealer lol. It has a fabtec 3.5” leveling kit in front it seems. Has the upper Control arms with uniball and all not just torsion key. I’m trying to figure out the rear. It has the fabtec dirty shocks all around too. Is the metal one a factory 2” and they added 2” block or is it all factory?

  Ha!! So GM Customer service, ive already been talking with someone on your email team and there is nothing they can do. So pretty consistent with everyone else’s experience- you can do NOTHING.. worthless emails. Sure glad i have 4 GM cars on our family cuz now its clear you dont care.. Sad and pathetic.
