Hey All...
I was wondering if anyone here (or USA) makes a hilux transfer case swap kit for Sierras?
I have tried searching through this forum, and Googling, but to no avail...
Also, which year hilux transfer cases are good? Does it matter which years they were? DO some work better or fit better than others?
I have a 92 Sierra, with spring over, and will soon have hilux diffs, and a 1.6 Vit motor...
Thanks Y'all!

Hilux T case kits
Hey that makes 2 of us did my case in 3 weeks ago totaly destryed my calmini gears there gose a grands worth of gears.Bought another case with series 3s in it but would like to drop in hilux cases running a dunnydore v6 with lux diffs.
Thinking Atlas 6.0 as to by gear box adaptor then get it fitted then by 2 hilux trans cases then the dual adaptor then a set of low range gears it is more expensive than bying an atlas case

Here is a link to a guy in the states that makes divorce kits for toyota T/cases this would be a good thing under a zook and the way the AUS dallor is a good time to buy.
I like the lux to Dana 300 adaptor they make its a cheep way to get reduction and front digs all at once and it is only 5" longer than a lux case

The only way I can think of doing it is via an OTT kicker.
This will put a hilux case behind a vitara gearbox, and will work nicely with hilux diffs.
However, the loss of an indirect high range will cause gearing issues- bear in mind that stock vitaras (also with a direct high range) run 5.12 gears with a 26" tyre. Expecting a vitara motor to push much tyre with 4.88's or even 5.29's and a direct high range will be a big ask.
As a result, I think the loss of lots of gearing options means that "upgrading" to a hilux case is not much on an advantage.
Just my 2c

But hey Im no mechanicNot really. Bear in mind that depending on the case you havem you have somewhere between a 1.4 and 1.7 high range ratio. Nobody get stuck into me about specific numbers please - they are only ballpark.
Best case scenario - 1.4:1 high range in a WT case -
Current cruise RPM= 3500rpm - with hilux case = 2500rpm
Worst case scenario - series 4 RH - 24% shorter high range = 1.74 (or so)
Current cruise= 3500rpm, new cruise = 2000rpm
IMHO there is no way the gearing is going to work out as well as with a sierra case, and you just won't get enough bottom end to pull decent tyres.
If you compare apples with apples, you have to remember that your "real" axle gearing is your low range X your axle, if you you want to compare high ranges with a car with a direct high.
WT sierra = 1.4X3.9= efective axle ratio = 5.46:1
Sierra, vitara diff gears, series 4 = 1.7X5.12 effective axle ratio = 8.7:1
Hilux, best case, 1.0X5.29 = 5.29
It is not hard to see that it will be a major struggle to run much tyre on the road with a direct transfer.
Wehn you add the hassle of trying to adapt a hilux case to a divorced application, or the cost of a kicker, having to centre the rear axle, buying 5.29 gears and probably still loosing 5th gear, I can't see it's worth it. On top of this, the lowest gearset for a hilux is still nothing special compared to sierra gears at about 4.7:1.
Just my opinion.

I am not aware of any divorce mounted cases that have an indirect high range.
Divorce mounted cases:
NP205 (1.96 low, weighs about 90kg)
Nissan MQ (2.00 low)
Atlas ($$$$)
NP200 (truck case)
Lada Niva
LJ suzuki
The only other cases with indirect high ranges are Range rover/land rover defender. Quite a useful case but very difficult to mate to a japanese manual IMHO.
PS not being funny, what do you have against the sierra case?

Lada Niva 1.2:1 High range and has a centre difflock (fulltime 4wd) but you can't get crawler gears as far as I know.Gwagensteve wrote:I am not aware of any divorce mounted cases that have an indirect high range.

Oooo i bet someone, somewhere has done it- 
lada owners are a special breed.
Don't think that a Niva case is a significant upgrade over a sierra case though.
Thanks for the info re the 1.2 high.

If the case is appropriately mounted you will not have problems with the sierra case- they are not weak and survive behind more tyre than a 33.
If you wanted to be totally sure you weren't going to break the case, have a look at roctoys case ring. this should fix that problem
Having said that, I have only seen broken cases in cars with modified mount arrangements. There is normally enough give in the stock rubbers/mount arms that they will bend before the case gives.

Best Gear set for a Lux case is 5.7........and there will be one in a sierra in OZ v soon 
wish I knew about the 5.7's earlier as they would be in the VIT for sure ....but I'd say I will have a set eventually for the next build
......
Can also try and PM ICE off the board as he may be-able to help with a divorced adaptor plate for the lux case ..if you wish to go this way ......
