the shackle side of the spring, in the stock location is where the new shackle mounts. and turned pointing down. basically if you turn the shackle up side down in the mount its in its equivilent to the shackle flip. you saying relocating the axle you mean the pinion angle is changed correct. yes the pinion angle is changed it will need to be shimmed ( with steel shims) to withinn 2 degrees of the transfercase out put. i hope this helps

foothillguy, are you sure it needs shims? its not like with a 4" lift springs, where the axle is still level.....with the shackle flip the pinion gets angled up towards the tcase. since the added lift is all at the back..

sure as it gets. the driveline yokes have to be withinn 2 degrees of each other to ensure no vibrations and max life for u joints. that is the correct way to line up u joints on a non cv style driveshaft if he had a cv you would want to point the rear end at the driveshaft thats how to set up a cv style driveshaft

thanks im here all week
