hiulx diffs

just wondering if anyone has done a write up about doing a spring under hilux diff conversion to wide track cause i'm a noob to this suzuki cult
Because you can't do "spoa" which diff would be more accessible to a spua
Ive done a 2inch body lift and 2inch spring lift so i dont want to go spoa if possible
Also would the steering be easier doing a spua setup

Have you considered MQ patrol diffs??

Hilux diffs (apart from being a stupid mod for a suzuki.... but everyone knows I think that anyway :D ) would be quite hard to set up SPUA. Possible, but hard. Spring pads, rear diff offset, no provision for steering in a SPUA application and rear diff offset are all issues.

MQ diffs are a better and cheaper alternative IMHO - if you are WT, the front axle will pretty much bolt in. even the steering is close.

Rear needs a bit of work with springpads, but the offset is much closer.

4.6:1 petrol ratios are a pretty good match for most taller tyred suzukis too.

you shouldn't really be able to break MQ's under a Suzuki.

Just my opinion.

whats the weight and pumpkin size on the mqs?

also what steering work is needed?

WMS difference to wt's

future thoughts are thinking

Drag link needs modification (would be subject to X-ray for engineer approval, possibly welded to an approved procedure)

width, from memory, is about the same as VIT so about 100mm over WT. pretty close to hilux, either way.

Rear is really heavy, but can be pretty heavily shaved.

front is kinda heavy too, but shouldn't be much worse than hilux. same centre as Navara rear.

Mock (ljxtreem) shoudl be able to remember more than me - we did it on nis NT chassis before he went all buggy styley on us.

MQ Diffs are cool :armsup:

My old red car, 1.6 carby, sierra 5 speed, series 3's, MQ's on 36's

Mine was a NT so it was a bit of work wide tracking the chassis. In the end its worthwhile if you want to run bigger tyres.

To run the bigger tyres (35" +) you will need to do lots of cutting. Mine had 2" body lift, extended shackles, rears up front, re drilled perches with a severley bashed back firewall. Engineers generally don't see major bashing and cutting as an "approved" modification.

Are the rear housings cast or steel (how easy to mod spring pads)

how much diff clearance do u lose out on compared to zook diffs, eg if u stick to 33's on each diff what do you loose.

at what point is it worth going for these? 33> or ?

James - what did u do for steering?

Steering, well mine wasn't engineered and was a trailer queen. I just fabbed/welded two drad links together, sleaved and plug welded.

Rear diff is steel tube, easily welded to.

Clearance, you loose a bit, can't remember how much. From memory Mock had his shaved to smaller than hilux.

Have to check if hilux is too wide in qld presuming your worried about SOA
i have no idea with widetraks

A) I though SPOA was out of the question in QLD
B) The centred rear diff and front diff centre to chassis clearance are the complications with Hilux SPUA, along with steering, I never mentioned overall width.

Is it possible to put mq diffs in a NT without moving the springs out?

The pumpkin on thr front diff would get in the way.

The rear could be done from memory (don't quote me on that though. )

have to ask but say you were considering coils wat would be your best option mq or gq. how would a 1.3 go pushing mq or gqs.
thanx

a) yes
b) meant to say track width also isnt allowed past 50mm wider.
i dont no how wide a widetrack is compared to a hilux.

Yes and no. Rears are fine. On the front, the way that Mock (ljxtreem) did it was to widen the front short side 4" this aligns the pumpkin the the right spot, but this made the front end very wide.

You could widen the short side and shorten the long side. This would do the trick and get the diff in the right spot and the width whatever was needed.

pitty your in newy. :lol:

would realy like to put gqs in but dont know if my zook would move with them. ar they much heavier than mqs.

changing axle length that sound like a lot of custom bother with one off axles etc... and i spoke to an engineer who would aprove a spoa as long as i use hilux and didnt have more than 160mm bum stop travel

as far as width hilux with navara offset wheels is the same as wt diffs with f100 offset, as long as he mesures track some mesure disc to disc then your stuffed from memory 120mm difference wt to hilux can check as have both here!

and some one ask about gq there huge dont go there for big $$$$ comp only over kill may as well go dana 60's

Yeah, fair point but that's only necessary with NT spring spacing. It should be pretty much impossible to break them, and the core long side/short side MQ axles are sooooo sheap that even resplined they are probably less than a replacement WT CV from a wrecker.

thats a fair arguement to i'll give you that once you go bigger than 31's on zook and drive hard boom go th cv's and it adds up I ended up with 3 sets of hilux diffs when i wento buy 1 set and all it cost me was i had to pull a motor out of a volkswagon 1hr's work big deal i was happy so i'll go hilux what is the difference in track hilux vs mq

Posted: Thu May 03, 2007 7:33 am

Unsure, probably not much difference from what I have seen.

Be careful, even though an engineer aproves a modification, it still doesnt mean its legal on the road. Being in QLD, i though SPOA was illegal no matter what diffs etc were used. An engineer may approve the work, but the authorites may still deem your rig illegal.

I know, that sux the big one, and I'm not doing it for that reson doing diff on springs so it looks right from a distance i dont want to talk to the powers to be

Landcruiser 40 series diffs are the same width as hilux and share the same front axels,cvs,swivel hubs,brakes,ect.The rears are different but the full floaters would be unbreakable in a zook anyway.They come sprung under but the spring mounts have to be moved and changed to suit your springs.The front pumpkin lines up sweet and the rear is only off by 20mm.Clearance is also only 13mm less than hilux but the extra strength is worth it(not that youll break luxs) but some 300Ms axles and youll have trouble breaking them ever.You should beable to use a 60 series draglink but you have to drill the tapers on the tie rod & pitman arm to suit.Also if you want to use zook drive shafts you need to get multi fit hilux pinion flanges and move your front diff forward 30mm and your rear back 30mm then they should just bolt up. You also have to make new fish plates and use cruiser Ubolts.

I agree, 40 series and 60 series axles are good candidates, but they are more work to fit and have less desirable gear ratios. 4.1 vs common 4.6 for MQ.

An MQ front has comparable axle/CV strength to a 40, and is a bolt in on stock spring pads on the front for a SPUA application, which is not the case for a landcruiser diff.

I agree that the rear floater is an advantage of the cruiser diffs, but MQ rear bearings and axles are more than enough for a sierra.

13mm is a lot of clearance - it is 1" more tyre. (this is an issue ith MQ's as well) if you compared the ground clearance with suzuki diffs, you have to run 2 or 3" more tyre than you had on suzuki diffs just to have the same clearance. This is one of the problems with bigger diff swaps, certainly in the terrain we have in victoria - lots of deep ruts.

I have 230ish turbo'd hp in my sierra I dont use low range as there is no point i have 4.11 now and doing 3500+ rpm at 100ks I want to run some thing a round 3.5 - 3.7's to fix this do 40's or mq have that option hilux does ??

Aren't Rangie diffs the only ones with ratios in the 3.5-3.7 range?

as low as 3.3 can be found in 2wd hilux and hiace vans etc..
