Rear locker for 3rd gens?

[jwilliams3]

Anyone make lockers for our 11. 5 AAM rear axles?

 

[Diesel Nut]

I want one but I think the dealer charges like $2000 parts for the factory posi. Little spendy. I think if someone can find a supplier cheap there will be alot of people interested. . . . . Myself included!

 

[mrsnow]

I am in the same boat. Why they would make a truck with this much power and not offer a locking rear as a standard feature. Does not seem to be any aftermarket support for these axles either.

ARB is working on thier Air Locker, I'm on the list for info when it comes available. I think I found a link at thier website.

The only locker currently available is the Eaton E-Locker and it is only available for the front differential. I'm tired of waiting so I'm taking my truck down to Unitrax this week and having them install the factory limited-slip (currently have open diffs).

 

[fyrescott]

I can understand a Limited Slip/Posi for these trucks. But why would anyone want a fulltime locker???? An ARB would be ideal but not a fulltime locker.

 

[CSilkowski]

I agree. Don't know why anyone would want a fulltime locker. I think the reference to 'locker' here must be directed towards a driver controlled locker like the ARB or the E-locker.

 

[fyrescott]

Yeah you are probably right... .

 

[Diesel Nut]

I was referring to the factory LSD.

No civilian pickup truck has been offered with a factory locker in about 30 years.

I don't know what you're talking about, "fulltime locker. " There is no such thing. An ARB would be what would be referred to as a "Selectable" locker. Most other lockers fall into the catagory of "Automatic" lockers in which they engage and disengage themselves. This is actually what I'd prefer for my truck but it is not offered... . yet.

AAM makes a combo LSD/Locker for the 10. 5 which is used on the new Power Wagon. Don't know if it's adaptable to the 11. 5. They also have the front for the 9. 2. Otherwise, like other said wait for ARBor check Eaton. Let us know what you find out.

A Detroit Locker is a fulltime/automatic locker. It does not engage/disengage constantly and when it does it sounds like someone smacked your third member with a sledgehammer. So there is such a thing :-laf The only difference between ARB and Detroit is one you self engage and the other is constant.

 

[JHardwick]

have a spool machined up, she'll be locked for life, LOL

 

[fyrescott]

There you go JHardwick... Spool 'em up. No question on whether it's locked or not.

A Detroit is not a full time locker. Not only do I have a Detroit in my trail rig, I am a dealer for the product.



A Detroit Locker is an automatic locking differential. It is only locked when input torque is supplied. It is not "constant"ly locked. Yes, automatic lockers do make some noise occassionally when they lock. Over the Diesel engine I doubt you'd even be able to hear it.



Like I said I don't know where you guys got the term, "full time" locker. There is no such thing, unless you're referring to a spool.

A Detroit Locker is normally locked full time. A sharp corner on dry pavement can un-lock it, and if enough torque is applied or the vehicle straigtens out it will re-lock.



From what I remember, it is merely a cervic type coupling loaded with heavy die springs ... ... ... . this may be too simplistic a description.



Anyway, I've read enough and responded to a few of these LSD threads. All I can say is my LSD wears my rear tires faster than my fronts, and works fine in soupy conditions ... ... ... ... no need for any type of locker here.

Once again, a Detroit locker is NOT a full time locking differential if there is such a thing. It will unlock with no input torque on the pinion and lock when input torque is applied.



All limited slip/torque biasing differentials are never 100% locked, and most cannot be 100% unlocked. A Detroit locker can be both... 100% locked, and 100% unlocked... . there is just nowhere inbetween those two.



A properly operating mechanical locking diff will unlock to allow for turning, if the driver allows it to.



Think of it as the driver's right foot turns it on and off, instead of the switch you have with an ARB.

I never called it a fulltime locker.



I think what you are trying to say is that either axle is allowed to unlock and run faster than the ring gear is being driven. Just backing out of the throttle and coasting does not unlock the differential.



Let say we are powering from a stop and making a right hand turn ... ... ..... the left rear is unlocked an allowed to turn faster than the right rear.



Now we are coasting and the torque is being applied from the tires, we make the same sharp right hander, and again, the LR (outside) axle is unlocked and allowed to turn faster than the right rear.



In either of the situations, if the throttle is applied in a manner that the right rear can spin and catch up to the left rear, it will lock. Or if the corner is completed with no wheel spin(un-locked), once the vehicle straightens out, it will lock.



Is this what you were trying to say?

It will unlock with no input torque on the pinion and lock when input torque is applied.

You didn't really mean this did you?

That is a possibility, yes.

Just backing out of the throttle and coasting does not unlock the differential.

Yes it does.

If you're powering from a stop, the diff is locked.

False. Input torque locks it, not the turning of the axleshafts.

Is this what you were trying to say?

No it is not.

You didn't really mean this did you?

Yes I did.

Arb

ARB said that they shipped the axels to their Australia facility and might have something by the end of the year.

My limited slip or suregrip or what ever it is called in these trucks works great on the street and level dirt areas. When I climb or get off camber much I have to do the preload the brake deal to try and distribute the power to the ground. This is aggravating and I am looking forward to the ARB solution.
