locker ???'s

I was looking at lockers today and am kinda confused about the different types. I want to know what the difference is between a gearless locker (like detroits), a soft locker, and an E-Z locker. can anyone help with my confusion? thanks

detroit lockers are like a clutch and they lock in that way(friction plate), i have no idea what a soft locker is, an E-Z locker or an aussie locker lock up when torque is sent through the wheels or something, they have springs and gears, and a manual locker lock together the diff when it is engaged, does that make sense?

A soft locker is basically an EZ locker. Same thing.

if they are the same thing then why the change in name? sorry for all the ??'S but I'm looking at getting something in the next few months and I want to make sure that I get what fits me.

and what I ment by detroits with the gearless locker is that they have one and I wanted to know what the difference was in the gearless locker (becides the obvious 'less the gears' factor)

well i think soft locker may be a generic term and then there is aussie and E-Z lock that are the brand names

adn lets see, the difference is that the gearless lockers dont lock up as easily and when they do lock up they still can slip a little when you go around turns, they also dont make the clanking noise that the geared lockers do, so over all they are quieter more predictable, and they can be used in the rear because of this, how they work i dont know, besides that they have like little clutches and clutch plates in them and thats why you have to use a different kind of diff fluid so you dont mess up the friction plate

okay... lets review lockers:

All true lockers do the same thing, lock your axle shafts together so that both are turning, vs your spider gears which will let all the power be sent to the shaft with the least resistance, hence that spinning tire on the trail.

Detroit locker does not use clutch plates as far as I know. The detroit true-track limited slip does as I recall. The soft version was one that didn't lock up as "hard" on the street in turns etc. However it still lets you now its back there and at certain times you will think your axle has just blown up from the sound of it unloading or loading up. The detroit replaces not only your spider gears but also your carrier.

The ez-locker, while still a locker only replaces your spider gears and is not as strong as the detroit (ARB/OX etc) This is often called a lunch box locker.In my experience it has more failures than other drop in style lockers such as lock-rights.

thanks 4jeepn, that was a little better I can at least go out and kinda know what I'm talking about when looking.

Also from what I understand the rear D35 is not strong enough to throw a locker into it? is this correct?

4Jeep is correct. If you are going to buy a lunch box locker (they go many names) then dont buy an e-z locker. They have a terrible track record. Lock-right would not be your best choice either. They are alright but I have still heard of them failing more often than not.My suggestion, if you wanna do this cheaply but still have a good locking system, would be to go with an Aussie locker. Its the same style but built much better. What happened was the designer of Lock-rite ended up leaving the company for one reason or another and ended up redesigning it to make a stronger unit. He built these new lockers when he joined up with Aussie, thus they have one of the best drop in lockers available. Another great thing about that type of locker is that any home mechanic can install it with simple tools since your simply replacing the spyder gears. That means you dont have to adjust the backlash or worry about your ring and pinion set up. With Detroit style lockers where the entire carrier is replaced these things have to be delt with since the ring and pinion must be changed to the new unit. One other soft locker that I would highly suggest checking out is the Powertrax no-slip locker. Its a bit more pricey than the Aussie but its another great one and it does great on road (can barely hear it). Unless of course this is going to be a straight trail rig that will get trailered. In that case just weld the spyders and save yourself the $$. Just remember you can never unlock it then unless you buy a whole new carrier and spyders though.

no this is my DD so I don't think that I will be doing the lincon locker trick. I've been looking at the aussie for awhile now and I think that is the one I'm gonna go with when it comes time to do it. what do you mean when you say that with the detroit you have to deal wtih the backlash and ring and pinion? is it really that hard? is the aussie really gonna be that loud on road that I'm gonna want to look at the Powertrax no-slip?

Man- There's a bunch of bad info here!!
4Jeepin was correct when he said that Detroit don't use friction clutches. They have clutches but they use a 'dog' clutch which is a gear.
Truetracs do not have clutches. They are a helical gear driven limited slip (LSD) unit. They are, far and away, the best LSD for any off road use.
Aussie Locker is almost identical to Lock Rights or EZ Lockers. They are well built and are built to extremely tight tolerences but they are almost clones of the others. Their real advantage over the others is their warranty an dthe fact that sell direct (cheaper than the others). The downside to Aussie, EZ and Lock Rights (all known as ' Lunch box lockers') is the fact that they use the factory case. The factory case is much weaker than a full case Detroit Locker. I've seen many broken lunch boxes on the side of the trail. They also wear and wear out. A Detroit has a part called a hold out ring which allows the gears to pass by each other (when unlocked) without contact. The lunch box lockers don't have this feature. This accounts for the clicking you hear. Personally, I only recommend a lunch box locker for a front application. They fail frequently and I'd rather lose the front than the rear, especially with a daily driver. A lunch box locker is almost never considered the final step in a axle build. It is usually just an interim step on the way to a good, full case locker.
The factory Trac Loc is a POS. For most people they are marginally even considered an LSD. They are a clutch driven design and fail frequently. Because of their design, it is usually not known when the clutches fail, you just get the typical '1 wheel peel'.

^^ X2 I dont know a ton about lockers. I just try to give out the best knowledge I have from what I have learned. I know enough but deff. listen to digger. He seems to know his stuff. Id say an Aussie is fine on a DD if your not gonna be runnin mcuh larger than 32" tires if you are still going to have stock axle shafts. Like he said though, they are more prone to failure than a full case locker. Its a cheaper way to go and you'll deff. notice the difference but they will wear out over time. It all depends on your long term and what your gonna want to do.
