Do you have a side shot of your set up??Metalcloak lifts are one of the most flexible mid arm systems out there. Because of that, they include shock relocation brackets that move them outwards to clear the frame at full wheel droop. You're best off with a backspace no bigger than 4.5".
I've got the 3.5" Gamechanger, and 38x13.5 Pat's with 17x9 wheels with 4.53" of backspace and a -12 offset.
