Hi all,
I'm currently looking at ways to improve my crawl ratio. I'm running the standard Gen 1 NG Pajero, with a diff ratio of 4.625 and transfer case of 1.9. I've gone up 5 inches in the tyres and as you can imagine, the car is picking up some pace down hills!
I've looked around here and the only things I can look do are:
1. Get a set of crawler gears which reduce transfer case to 2.85 (instead of 1.9). That is about $1000 AUD. Not great in terms of the $$$.
Secondly mates have suggested that I go to a lower diff ratio of 4.875 - which from my calculation would give me another 5-7% redction maximum. Since I have lost around 18.5% from the tyre change, that hardly seems worth the $600 for the new diff centers.
Thirdly there is rumor of 5.29 ratios having existed once upon a time, but nobody seems able to get them.
Any suggestions on what else I could do? I'm hoping that some of you guys have had the same problem and found a solution, or that someone in the USA retails better crawler products, which you could point me at

Your mates in Australia gave you the full run down.
Another alternative is to work with an aftermarket manufacturer like Marlin or Atlas to serially mount the transfer cases but that will be extremely $$$.
Just thinking off the cuff and out loud but maybe you could look at building yourself an X-case adapter plate and put a different X case on but I don't know anyone whos done that or if it's even possible.

Yeah I thought about maybe pulling one out of a landrover (3.23 reduction) but I have no idea how to adapt it.
As for my friends - man I hate it when they are right :)

Get both the crawler gears and the 4.88's It's only your money not mine. On another note, never trust advice you get over the internet.

Unless you can do most of the work yourself the most economical are the 2.85 gears.
These are the same price as Nissan & Toyo gearsets.
Jeep transfer cases are expensive here not like the US where you can get them for $100, here because they are much rarer you would be looking at around $1K anyway unless you had special contacts.
The Jeep t/case will only work with the V6 auto as the output shaft is 23 spline the 5sp is 24 spline.
Even 4.88's are going to be $400-$500Ea from a junkyard here.

Has anyone gone through the trouble of doing a price check at a machineshop that is willing to mate 2 mitsu cases together. I know what it costs up here, it's $2400 USD wich sounds way too high for some people but the currency playes a big role in this. USD is crapping out against the ISK, wich comes in handy when shoping on ebay.
For a small workshop it shouldn't cost more than $1500 in the US even less since it's 2 identical cases and only a matter of removing the FWD part and making adapter plates and welding them to the cases.
It's a HUGE country and I'll bet my wife there's someone over there that will do it for a resonable fee. 
$2400 US are around 1000 cheeseburgers at McDonalds over here. Multiply your local McPrices with 1000 and that should be somewhat the price of a Dual T-case setup. This is supposedly the most acurate way to calculate cost between country's.

Party Truck, that idea has been thrown about a little. I know of (but have not met) a guy down here who has done it possibly with the help of Cheezy racing. Apparently its an awesome mod if you pull it off. He's a fabricator though and did it himself.
Not heard of anybody who does it as a standard product offering, but I'll have to check it out.
On a side note - Mister Bishi: I thought that Marks were down to 1 unit of the 2.85's?
Also, having 2.85's & 4.88...how much has that helped?

Those that have pondered that here all conclude that it would only be an option for an LWB. Not enough rear shaft to loose on an SWB. Having had two Gen I 4-cyl 5-spds in the garage at once, along with a couple of drive shafts, I did play tinker toy with them and they sure would all go together rather easily it seemed. The diameters and spline of all the shafts are the same. Cut here, splice there, weld a little, bolt it all up...
Of course when it's all said and done, you'd likely spend as much as the 2.85s. At least the parts for the 2.82s. So you may as well go that route, especially if you can swing the labor on your own. Hell, I did, so anybody can!

One thing that is nice with the dual t-case setup over the 2.85 gears is that you have the option of the stock 1.9 low range for the more moderate hills and trails and if you have to do something more serious you double it with the other stick and you have 3.8:1 low-low range.
It eliminates the too low for this or too high for that dillema on the T-case that some people have.
