Outer Limits 4x4 Board

i have a 91 lux with ome 2 inch springs and ome extended shackles
just put on some 33x12.5s and they are scrubbing badly
ive done a search and found a bit of info on RUF and also re drilling the spring perches but not sure which one to do, is one considered better then the other?
2 inch body lift coming up but dont think that will give me enough clearance without moving the diff foward.

thanks

Drilling perches is far easier than ruf, and u retain the same height. But you have to adjust your drag link.
So that and body lift will easy clear 33's.

alright thank for that
drilling the perches do you just drill a hole on the diff housing back from the factory locating hole or you drill them in the actual springs forward from the factory hole?
and i think i want to move it forward about 35mm does that sound right?

Drill the perch on your diff housing, do not drill your spring pack I did this years ago and some of the leaves snapped on the old hole.
