arb locker

[916S14]

I heard that a company out there sells mechanical and hydrolic lockers for 240's just like on the trucks. I searched all over and found nothing. Have any of you heard anything like this?

ARB offers one for the R200A/c200 with 29 spline axles.
It might fit into the S14 R200 case.
It's ARB part number RD107.

You could try it and be a pioneer for $784.00.

It will fit the s14 case. Sounds pretty epic, no more chatter or chirping through parking lots.

But is it going to lock up like a viscous?

[916S14]

It locks up better than a viscous, much better. It uses springs and teeth instead of clutches so the lock is pretty much instant. And you can adjust your torque setting. Anyone know if they have mechanical lockers? cause the air ones are a grip. Someone told me that mechanical ones are like 300....?

If this fits in an R200 case, I guess that means that the C200a centersection is the same as the R200s that we have.

If that's the case, wouldn't that mean that we could also use c200 ring and pinion sets.
I have a feeling that the Nismo 4.636 R+P and the Xterra 4.636 are the same part.

Also, ARB only makes an air locker for the c200/r200 as far as I know.
Offroad lockers lock pretty damned hard too.
I recall hearing that Detroit Locker makes a locker for the R180 centersection in the Nissan 720 p'up, but that's of no use to us.

ARB makes locking differentials for off-roaders, so I'd say it's a safe bet that it'll lock up better than a viscous.

Yeah, I actually meant to say helical.. cant be right all the time...

Its says the lock is activated via a switch that sends air pressure to the locker causing it to lock. What if you rigged up some switches that would activate lock on full throttle and 0 throttle, wouldn't it be very similar to a 2-way clutch type? Then you could adjust part throttle lock just by moving that switch around... I would guess that a 2-way would be simpler b/c an air locker would require a compresser and tank maybe?:confused:

yea i heard about the detroit locker too. But i'm really looking for a mechanical locker. I did hear something about a mustang locker fitting a 240z... but i'm not sure of the specs on all that.

[smelly240]

i dont understand the reason to get this over a clutch type - just so u can park and have it quiet to daily drive and then lock it up? Or is there something else i'm missing?

[916S14]

The reason i want a mechanical one is because its cheap, better than welding one, and yeah i dont have money for a 2 way clutch type.

Hah, awesome link. That clemson 4 wheeling place is honestly about 4 miles from my house.

[240trainee]

basiclly, you can choose between open or spool/ welded.

so driving around you get the seamlessness of an open diff, and you can lock it when you want.

my Jeep buddies have been wanting me to do this for a while.
