Mike, I have a Detroit soft locker, 31 spline in back and a Gearless locker in front on 37" MTRs. Very capable trail rider. The lockers were the second OMG upgrade, after power disc brakes. Next time they wouldn't be power. The lunchbox locker will work fine for you if you don't wheel at 5K rpm all the time. It will stand up to 33 or 35" tires without a problem. I've been completly sold on mine. Not broken anything and still on stock front axles with a spare set under the hood. Hard to justify $600+ for anything else. Stock open carrier, $45, lucnchbox locker, $275. You can probably assemble it yourself. You will be absolutely amazed at the difference.
Nice to meet you,
Tim
