I am looking to get a 3 series posi carrier for my differential and was told by a salesperson to stay away from Auburn Posi's because they can't be rebuilt and can't handle burnouts. Is this true or not. If anyone has either let me know how they are, or better yet if anyone has an Eaton for sale let me know. I would prefer an Eaton but they are expensive and hard to find. I am inclined to believe him because I see alot of the Auburns for sale cheaper and are usually unused. Any info would help.

i just learned about this this weekend so someone might be able to help more than me but here it goes...

with auburn both tires don't always lock up when dong the burn out. One tire would spin then not the other then next run it might be the other way around the guy that was running it didn't like it at all but like i said someone else might be more help...

Auburn posi's have a poor reputation here. There are a lot of people here that have experienced many 1 wheel burnouts. They aren't rebuildable, unlike the Eaton. I have a Pro-Series Auburn in mine, and if I could afford a new Eaton, I would do it tomorrow. If you want a worry free posi, get the Eaton. They shouldn't be too hard to find, as they are currently making them new.

EATON EATON EATON EATON EATON EATON!!!!!!!!!!!

Sorry, I've had personal experiecne with both Auburn and Eaton posi units. I had a brand new 3 series auburn pro series posi in my 12 bolt, even when brand new sometimes would only spin one tire, after 3 months it was completely toast, tons of metal shavings in the rear end.

I replaced it with a brand new Eaton 3 series unit, $350, a world of difference. It always spins both tires, and locks up much more firmly than the auburn. Plus, when it eventually wears out one day, it rebuildable.

Go with the Eaton, no reason to even consider the Auburn units.

Good luck,

I hate to knock the Auburn because for years they were the only ones who cared enough to make posi units for a lot of rear ends that had no other posi available. I have had a lot of experience with both Auburn and Eaton and I can say without a doubt that Eaton is by far the best. They are not very expensive either. I have been selling tne new ones for $348, which is cheaper than the Auburn in Summit the last time I checked.

My son tried an auburn when he raced in the stock class on dirt. Never made one full season! We figure at best,400 laps on a 1/4 mile oval.
