What do you guys think? oh I currently have 3.73's now.
Do the 4.56s. 4.10s are not enough of a difference from 3.73s to warrant the $$$ to do the swap. If you EVER think you might go to 35s, think long and hard about 4.88s.
Also, might as well do some lockers while you are in there. Save about $500 down the road by not having to tear into the diffs twice, and depending on WHAT lockers you consider, might get a full case locker instead of a new carrier and a lunchbox for the rear. That way, you get a much stronger carrier(Detroit/ARB) for just a little more than a lunchbox locker and stock carrier.
