yeah, i ran 4'' blocks years ago, big mistake, they never broke but scrub line can be a bitch, plus i had bad axle wrap, but other than that i never had a prob, they where pinion angled blocks. but ne wayz, dont do with anything over a 3'', and like they said, if you have to pull your leaf pack apart and remove one, just make sure you dont remove the load leaf( bottom one) and youll be fine, might have to trim your bumps though.
