hey guys
soo i have purchased the O.R.A 4.5" kit.
now im thinking possibly looking at different diffs?
maybe hilux? only concern is the little jimny diffs are off center? and/or not to sure wether the hilux ever came out with the off centered diff?
if so is it a cut n weld sort of job ?
or quite difficult?
thanks

[zooky08]

Pretty sure every one goes hilux front and bundera rear as the bundera diff is offset

It will be a BIG job to fit to a jimny. It has been done, though I am unsure if it is engineerable in QLD.

I know this is all a bit Grumpo, but if you need to ask these sort of questions it might not be the job for you. It's definitely not straightforward, regardless of its legality.

The bigger question is if you're very sure where your heading with this build. The jimny's we've had down here in the club have all reduced their lift height down to the bare minimum and used trimming and bumpstop spacing to run the tyres they want rather than lift.

From what I've seen they're pretty spooky with lift in them. The weight of the hilux diffs will help this, but what you gain in stability you loose in ground clearance and increased unsprung weight.... and how much tyre do you want to run to justify those diffs? Jimny's have tiny guards and their hard to cut far enough to run a big tyre at a sensible overall height that allows you to make the most of the traction the big tyres have.

Just some thoughts.

How much experience do you have with suzuki's off road? Just because you can buy a part doesn't mean it's a good idea.

iv herd its pointless running hiluxs diffs on a zook unless ur going 35s +
if u run 33s or lower u lose dif clearance because of the size of the difs ??

[Gwagensteve]

I'd agree with that Tryhard.

The problem with Jimny's is that axle strength upgrades are much more expensive than for sierras. They never break anything on a 30" tyre, but at 32" (and not even a wide 32 - 235/85/16) they might as well be made of glass - even driven gently it was taking out multiple driveline components on medium/hard trips

We have a Jimny in the club here in Vic with 34 9.5 15 swampers on it and it hasn't been very reliable, driveline wise.

Hilux diffs look like the answer (or hilux/bundera) but what's the point if you're getting outdriven by a much more standard car on 31's?

sorry mate but that is garbage. my sierra on 31s has the same(to the mm) diff clearance
as my hj75 that is on 33s also my hj is the model with the big diffs both front and rear.
i would be prepared to bet money that a hilux on 32s would have more diff clearance then a sierra on 31s.


i have actually climbed under cars with a tape measure so this is first hand info not another internet folly

Hilux housing, centre line to bottom of plug ring, 128-130mm


Theory:

314.5mm from ground to plug ring clearance on an exact 35" tyre with Hilux diffs

289.1mm from ground to plug ring clearance on an exact 33" tyre with Hilux diffs

263.7mm from ground to plug ring clearance on an exact 31" tyre with Hilux diffs

Practical:

This will change depending on pinion angle, the housing is rotated so the angle may reduce clearance because squarish of the corners of the housing, Clearance will also change with weights, tyre pressures, tyre size, and conditions.




Anyone got a sierra/ rear Jimny housing to measure for theory? (jimny fronts are smaller than sierra's)

But why would you bother going to all the hassles of fitting Lux diffs, when you can reliably run up to a 34" tyre on zook diffs ? The extra width isnt necessarily needed if the car is setup with a reasonable hieght suspension.

[shep]

width, gearing options, housing strength, ability to legally fit larger tyres and availability of parts.

want me to keep going

width, Like I said set your suspension up properly and you dont need the extra width
gearing options, Not sure but there is about the same number of zook gearing options too
housing strength, The only way I have seen a housing bend is if you are stupid enough to jump your car
ability to legally fit larger tyres Maybe, I never had to worry about legalities
and availability of parts. Fuck me if you cant find zook parts anywhere in aus or OS then you are doing something wrong.

We arnt talking sierra here, we are talking Jimnywith the weak as piss fronts.

There is a reason why comp suzuki's run lux diffs. Running twin locked 35's+ Strong and lighter then pootrols centres/housings! And easily upgradable further.

If your anywhere, You have more hope in finding a lux centre in the wreckers than a suzuki one to get you out of the shit asap if stuck somewhere.

what is the OP's car? tell me where you will get stuff for a jimny.
when was the last time you got cheap sierra parts that can handle big tyres? hilux CVs are on the shelf at your local repco.
no lift and big tyres might work where you are but it would suck dogs dicks where i am.
i have never jumped a car but have bent diffs and broken chassis mounts with out much effort.

aussie is a rather large place and what works where you are is not the be all and end all.

just because something is different to what you have doesn't make it wrong
it just makes it different.

i think the correct 4wding formula is lift+width+1500km fuel range= awesome
does that make all you dudes that dont go more then 50km from home wrong?
personally i think it would be worth trying a jimney on lux diffs because
it gives the opportunity to use a better front suspension design and to get
rid of a diff that has little to no aftermarket backup and also to add a easy
100mm of width.

Forgot about the Jimny part, my mistake And I would love to be able to wheel something that needed big lift within 50 K's of home.
