I set my trooper axle up for a four inch lift and a inch stretch. Cycled the suspension and it won't clear the gas tank so I am going back to my original plan of rocking it in the stock location with 2 inches of lift. Seeing as I burned on the perches for a 4 ish inch lift and am going back to 2.5 can I use some shims to reduce my pinion angle a degree and a half?
