The larger the tire, the higher the center of the axle is (AKA increased ground clearance) thus changing the angle between the output of the transfer case and the input of the axle.

Oh, and BTW, I was running a 6 degree shim on the Rancho lift. It was even worse before I put in the shims.

As I look back at both lifts, all things were equal except the tire size. Same lift height, same axles, same driveshafts, same degree shim (OME has a shim on the spring from the factory), different tire size. One needed the drop, one did not. Logic would dictate that the tire size changed the geometry.

I don't think tire size changes it at all. It just puts te axle higher, out springs are what makes the driveline angles.. Hell I could put 44 in tires and my driveline angle would be the same. Please somebody correct me if I am wrong.
