Pnuematic or Electric??

Well, I just found out my truck has a 8.8" 4.10LS in it (I know, bout time, right?)

So I'm thinking... I know I should go with a locker, becuase I do alot of mild off-roading (mild only becuase I don't have a locker), SO...................

Should I go with an ARB Air Locker or an ??Detroit?? Electric Locker (can't remember the brand)???

They are both about the same price +/-$50. Which one?

I would like to hear some good opinions........thanks.

Eaton ELocker all the way. I have it, love it. No need for air supply, easy to fix if you happen to somehow cut a wire.

I may be selling mine, as I no longer offroad the Ranger. As soon as I can find an 8.8 with 4.10 and LS to replace my current axle I'll be selling it.

Too bad you didn't need it BEFORE I sold off the parts to my old axle!

Yes, Eaton eLocker or an Auburn Ected. Pneumatic has a long history both good and bad and the air systems can be a pain and it's additional infrastructure to install and maintain.

I say electric. I love my Auburn, through the Eaton may be heavier duty.

Nothing, not much out there for the 28 spline 8.8. Moser can make some stronger shafts, but you're still stuck with the 28 splines.

Yeah, I looked at those lastnight. A 4.56 gear is about as low as you can go becuase of the pinion beign too small, right?

I have an Eaton ( Same as Carl/Bucks ) . Its seen a lot of hard street use. Hasn't twitched at all. Auburn makes a comparable unit ( The one John/ne3lz has ). All things considered, I would say the difference between the 2 is very minimal and both perform outstanding.

So would I lose the Limited slip if I put a locker in there? Isn't there an electric locker that is an LSD until it's engaged?

That's the Auburn. But be advised that it is not a mechanical locker in that there is not metal to metal engagement. From what John told me it uses current to lock it up. If I understand correctly, then that worries me about it, I'd rather have a positive lock up

oh and you can defintly run all the way to 5.13s on an 8.8, or if you want they have 4.88s and 4.56s and 4.10... the 8.8 is plenty big enough to run all of them and there are plenty of people abusing the 28-spline 8.8 with 5.13s and 36-38s. if you are worried about the 28-spline shafts you can get some yukon shafts for it.

But the pinion shaft is the same size for the 8.8" and the 7.5" that's why I was asking.

Well, since the Auburn locker doesn't have a metal-to-metal lock, not trying to say it's inferior, I'll go with the Eaton E-Locker and a set of Moser axles. Still not sure what size tires I wanna run, though.

While you are doing all that you could swap in an explorer axle...
it has the 31 splines that are susposed to be 34% stronger... also get a free
disc brake conversion.. but its a little bit of work. rewelding spring perches etc.
