I have Auburn Pro Front and rear ......it will wear out, as will any cluth type LS.....the Eatons are rebuildable, and can be had with an optional 800lb spring....someone in here got theirs from Randy's I believe......I went with Auburn because of the moderate off roading I do, and because I roadtrip this truck fairly often ....it has probably the tightest torque bias available, and it's half the price of an ARB.....I don't need lockers or 6" lift or 38's for what I do.....I have Moly shafts in my 10B/12B and I run 33's (AT on 8" street/MT on 10" for play}.....mostly Black Dirt Mud in Texas......I have yet to find a mud situation which will overcome the bias in either Auburn......as much as I like my setup, I'd opt for the Eaton with the bigger springs since it's rebuildable.....I think that most clutch types have a tighter bias than the gear type LS.....any LS is more forgiving to your front end parts, so you don't break as easily as with a full locker.......they all work, you just need to decide how you are gonna use it most of the time......there is no wear on front with the hubs unlocked.....good luck.....JD
Stuck?...Hell no..I still got some gas left..
