I was in same boat when I blew my rear diff....was regearing either way 4.56 or 4.88. I ended up going 4.56 cuz a few kept telling me the next size up the ring gear starts getting weaker n weaker. I was recommended to not go over 4.56 if staying with 33. But I do wish I had a lil more gear sometimes.
Nothing a supercharger won't fix lol
