i would highly discourage using a 4cyl. aussie in the rear of your truck. with 37's, and as much as you drive it, it wouldn't last long. they are only rated for 33's. running a 4cyl lunch box in the front is fine, but not for the rear. i blew apart a v6 with a lockrite in it, but that was after 5 years of daily driving it and several hard wheeling trips. i'm not too fond of arb's or e-lockers. know too many people with them that have problems and they don't know it til they need it. everything from a leaky air line, bad regulator, stuck gears on the e-lockers, etc. if anything, i would stick with your detroit in the rear. one reason why i went spool in the rear, not popping, and extremely predictable. the tire wear on a daily driver would suck though. leave it alone and buy my civic for $1500, problem solved
