hope people are still looking at this!

this is good stuff first off, especially for a first time wrencher. i've been wanting to get something for my front axle, and i'm just not sure. i want something that'll last like a locker and be good for riding in the dunes up here in michigan. and i've been reading a little about this ox locker. do any of you guys have em? what are the pros and cons? are they just as good or any better than other stuff? i have the original limit slip in my bronco and i've been thinking about a detroit in the rear. i also might upgrade to heavier duty axles, but for now i just have the d44 and 9inch, and i just talked to friend that could get me a good deal on a 429 for my beast. so we might be talking a "little bit" of an increase in power. so yeah, i'm just wondering what you guys with ox lockers think of em and if they aren't that great, what would better. thanks.

What about the Wayne "fozzy" Foster method?

I did a search and all I came up with was one lousy mention of the word "fozzy" and it was in the classifieds!

A "fozzy locker" is along the same lines as a "Lincoln locker" where the spider gears are welded. The difference is that instead of welding the gears to the carrier or to each other, only selected voids in between the spider gears are filled. When done properly, in essence it allows some differentiation between the axles until the filled teeth on the spiders come into contact with the teeth on the side gears. How much differentiation depends on how many teeth are filled in the spiders.

This is useful for giving the steering axle just enough differentiation to allow some amount of steering before full lockup which helps to keep the power steering fluid from boiling over not to mention making it a little easier to steer for those without any power steering at all.

FYI. There are NO clutches in a Lock Right. There are couplers and drivers.

Okay, so does this imply that the Detroit EZ-Locker is not intended for use in a vehicle with large tires?

I've seen EZ-Lockers hold up with up to 35" tires, but mostly in front axle applications. Above that, all bets are off. The manufacturer states in the supplied documentation that the locker is not intended for use with anything larger than 31" tires.

I would not use one in the rear of a Bronco with anything larger than 33" tires, and then I wouldn't expect it to last very long. YMMV

There are "lunch box" lockers for some of the 1-ton axles and those things are huge. you could run large tires with those. If you are running a stock 8.8, you are already pushing the envelope.

I was actually going to ask about that. I was planning on putting a lock right in my front 60 soon and was worried if itll hold up. I have 37s now... planning on 38s later this year. I know Andy has one in his and hes running 40s now so i figure id be fine.

I like lunchbox lockers for the front. I know lots of people who use them in '60 fronts with no trouble. I don't like them for the rear, even in 1-tons, because the rears work MUCH harder. I run a lockright in the front of my rig with 35" Krawlers. I would NOT run it in the rear.

Because they are two different types of LSD's.

No, a Trac Loc like what is used in the 8.8 and Dana axles. It's a specific type of lsd that uses a series of clutches and plates. The Posi-loc is gear-driven. Many people mislabel Trac-Loc as Posi, but that is not correct.

Your saying two different things now. "Posi-Traction" and "Limited Slip" are he same thing. Trac-loc is a limited slip type diff. Theyre the same thing.

The term PosiTraction originally referred to GM's LSD design from the 60's. It's since become sort of a generic term, but that's not really appropriate. The original GM PosiTraction unit and the Ford Trac-Loc (actually a Dana differential design) are both LSD's, but there are differences in their design. Because of this I always avoid the use of the GM term to refer to any and all LSD's, it causes more confusion than it clears up when the differential design can be very different. If I refer to a Posi differential, I'm referring to a Posi and that alone.

PosiTraction (or however they spell it) is a trademark owned by GM. It's a clutch type limited slip differential. GM also owns one called a Gov-loc which uses a flyweight assembly. IIRC Trac-loc is another trademarked name for a limited slip differential. Ford owns a name, Dana owns a name, I'm sure AAM owns yet another name, all for the same thing or a variation of it, clutch or cone type LSD's.

I have never seen spec books or maintenance manuals from Ford use the term posi-traction (GM's term). Ford generally use the generic term limited slip. GM used a lot of Eaton ls over the years.

Fine, if you want to argue over semantics, then you are correct. I give up.












(but that's the same thing as saying a Ford and a Chevy are the same thing, since they are both automobiles)
