not sure on the RE numbers, but if you want 33s on a 3inch lift you are going to be trimming a lot of fender off, needing long bumpstops, and not having much uptravel.
if you need a DD with occasional light wheeling, why not go 3" rustys and put 31" bfg ATs on there. I like truxus mts, but they wear quicker than ats and aren't necessary if you are on the road most of the time and don't wheel that much. A 4.5" kit will clear 33s. You can put 2" spacers on top of a 3" lift, but I wouldnt recommend it. you will need a heavy duty tracbar mount and a new tracbar for 4.5" lift. You won't NEED a new tracbar with a 3" lift but it doesn't hurt. Dont' do the 3" springs plus 2" spacers!! they ride like crap. you'll be at 5" of lift with short arms. much more than 5" of lift and it's time for either drop brackets or long arms.
