Unless you or a previous owner welded it up, it is an open or limited slip diff.
I dunno what you mean .....

I'm thinking he's thinking that the "cover" is welded up ...

This isn't like a dana, etc. axle. The Isuzu 12 bolt has a drop out third member.

i could take a picture and show you but what does
mean?
<img src="/forums/images/graemlins/confused.gif" alt="" />
i guess im thinking of the dana like you were saying where you can see the bolts holding on the plate that would allow you to service your axle

Dana-style axles have removable differential covers. This allows you to gain access to the inside of the axle without removing the shafts, carrier, etc. This also means that adding lockers or setting up gears must be done inside the axle. GM corporate 10, 12, and 14 bolt axles also use this design. The Isuzu corporate 8, 10, and 12-bolt axles, Toyota axles, Ford 9", etc use a 3rd-member style axle. There is no removable cover that allows easy viewing of the internal parts; but the entire 3rd-member (which houses the carrier and ring/pinion) can be removed as a unit. This allows lockers and gears to be set up on a bench, and then the complete assembly can be dropped back into place. Go look at the front of your rear axle (or the rear of your front axle) and you'll be able to see the large section that can be unbolted and removed.

BTW, yes, you have an Isuzu 12-bolt rear axle.

Reminder:

This thread is for the discussion of its topic.

If you want to know about welding diffs, what diff you have, what other locker options you have ect, please start a new thread.

well here we go. this is the GENERAL version of this project. let me throw some numbers at you guys and then we need to see how many are still interested.

the 10 bolt locker:

to do a 1 time limited production run of these the minimum order would be 75 units

turn around time is a minimum of 26 weeks from the time of my deposit

the retail of this run of 75+ will be around $450.00 each


12 Bolt rear:

this unit has to be "tooled" - there is currently no locker available (nor has there ever been). Unit has to be designed and tooled at a cost of roughly $5000.00

they are willing to make a very tiny run of 50 minimum. that means, that on top of the reg "wholesale" cost, there is about $100.00 worth of tooling per unit at this level.

if we did 5000 there would be $1 per <img src="/forums/images/graemlins/smile.gif" alt="" /> ............you see this is why Mfg' do not want to run small #'s - tooling is the same reguardless of how many you make.


to do a 1 time limited production run of these the minimum order would be 50 units

turn around time is a minimum of 26 (+8 for tooling and most likely a bit longer for prototype and test fitment) weeks from the time of my deposit

the retail on these 50+ units again, same as the 10 bolt would run around $475.00 each + the $100.00 per unit for tooling = final cost of $575.00 per unit. with a 1 time run of 50.


TERMS:

all units would have to be pre-paid
there would be no refunds on parts once you commit.

that is UNLESS for some reason they are not made, then payments would be returned...........But if you commit, and they are made, you pay for it .....if you take delivery or not.

all freight will be split down over the final # of units (getting the skid of 125+ units from SC to VA and then from VA to you )



SO..................there it is. that is the reality of this project. and...of course pricing is subject to change as materials and trasportation costs are changing on a weekly basis right now.

give me feedback. Now who's in?

I'm moving this out of sticky and down into the regular flow for a bit -- I bet it will get more responses.

Thanks, Matt, for undertaking this and keeping it on the radar. Let me highlight something that jumped out at me that shows your commitment to this: from the time of my deposit. This is SERIOUS, money-where-our-mouth is consequences -- we need to step up and commit if we can, or step back and get out of Matt's way if we cannot make the numbers. Don't take it personally -- this is business, and Matt will be on the hook for the deposit, regardless. Pre-paid, and no refunds on parts once you commit makes perfect sense in this context. Matt already has his reputation on the line, to get negotiations this far.

I don't know if this is do-able, frankly -- dunno if there are enough folks who can step up to commit. I hope so!

Review:
* 10 bolt locker: 75 units, $450 each, plus shipping
* 12 bolt locker: 50 units, $575 each, plus shipping

Thanks, Matt ... now let's see what the people can support...

Same here <img src="/forums/images/graemlins/scared.gif" alt="" /> Let me just throw this out there, though... Matt is well-established in the Isuzu aftermarket and has worked really hard to get the lockers this far. Everyone that is interested needs to step up now if this is going to happen. No waiting around to see what others do. If this one falls through, I wouldn't expect to ever see the opportunity again. I doubt Matt would ever give it another shot in the future and good luck finding a lesser-connected person that is able to pull strings the way he has to get this much accomplished. Lockers sure are nice; don't miss out on your chance to have one <img src="/forums/images/graemlins/kewl.gif" alt="" />

yep....to get the minimum out the door here we are talking about $62,500.00 ........so yeah, this is serious from my perspective......if the market calls for it.

if not, well...........then there is no market for this. <img src="/forums/images/graemlins/pfft.gif" alt="" />


what i really need now is to start compiling a list of Names, #'s, and adresses of the interested parties.

if it ends up looking like a go. i would then do a round of call backs to finalize the payments.

I am in, Matt you have my info let me know when and where. Do you want us to PM you with our info? Thanks your hard work on this. Don
