You can run 33's on a 60 with a 15x8 rim. Make sure, minimum 3.5" BS. If you can, see if you can fit a rim to
the front before you buy. TRE and caliper clearance are the issue. For minimal lift, I can only recommend OME.
I've been running them for years and they are the best. If you can find new stock height leafs, it will probably give
you 2" of lift, just getting back what has sagged away.
