Outer Limits 4x4 Board

hey i was just wondering what kind of work would be involved with putting bundera diffs in to a 96 model sierra so i can run my 33's on it i'm also interested with putting a 3 or 4 inch coil lift in it.

33's on a 96??? 96 would be a coily right???

I'd say - sell it, buy a WT leafy, 2" spring, 2" body and cut the guards will see you running 33s in no time (and cheap).

to do bundy diffs will mean a LOT of work and a LOT of $$$.

Do a search on coily SAS or hilux diffs. Tons of info has been done before.

okay ive seen ppl put hilux diffs in them before and just doing a soc but i don't have a whole lot of money to spend on it. but it would be good for a little project car.

no point as you are in QLD and it wont be legal

you sayyou don't have a lotof money to do it yet you'll need to do custom suspension to get it to work as the diffs aren't the reason you'll be able to run 33s. The coily has a crap suspension design that is limited in wheel travel and lift it can handle.

Then you have toworry about gearing to be able to drive the 33s, again custom as there are no gearing options for the chain driven tcase. So youllneed to buy a leafy tcase and then gears and then fab mounts, new driveshafts I believe as well.

Then you have to sort out steering withthe new diffs which willbe allcustpm as well. Braking system willneed tobesorted as well to match the Suzuki and Toyota parts.

Then you willneed to figure out flares etc to cover the wider diff and tyre combo. Starting to sound very expensive so far. Then you'll get pulled over by the cops and your vehicle will be defected and all of the work and money will be wasted.

yea okay well ive found a leafy anyway so i plan to be doing that up now thanks anyway

if it is a trailer car it wont matter. unless you speak to an engineer you never know what they will approve. in qld you cant go taller then 15mm and 30% wider then the stock tyre. bundys come with a 31 standard.

gearing is no big deal, leafy and coilt tcase mounts are the same. so you can put gears in a leafy case and bolt it in. you will need to use a leafy jackshaft. depending on the model the bundy diffs come from (petrol or diesel) the ratios will be different.

But he said he had little money to do it so that is major factor stopping the mods.

If he had 4.8 diffs in it on 33s the gearing wouold be back to standard.

but gimbo is right when he says that this will cost a bomb. I would just buy twin air lockers an inch or two bigger muddies, spring lift and you will proberly go just as far... don't let tyre size fool you into thinking that the more is better.

just run 33's on stock axles and get 6:5 gears, i did a comp and heaps of hard wheelin with mine before they went bang.

you can buy a lot of spare cv for the diff swap lol
you dont need big lift in a sierra any way with such a short wheelbase
2 in body 2 in spring and virtual lift and u should easy fit 33.
i had 31 with just bumpstop spacer and guard chop

the only reason i wanted to run 33s with the bundera diffs is because ive got the tyres of my 60 series pretty much brand new coopers and i didnt want them just to go to waste and i kno i wont get as much for them as i paid

Have you got access to a Bundy to check measurements on? Suspension mounts, spring locations etc etc. It won't just line up but it may not be too far out. Use all the bundy stuff you can. Coily may be easier as it has spring seats etc.

Steering, I don't know the geometry of the Bundy but it could be done. Get a custom tie rod made up. Brakes, just new hoses to suit, may need a different master cylinder to get volumes right.

Good luck twin air locking a coily

What won't be legal? diff swaps sure are legal if done correctly, just putting Toyota crap in a Suzuki is immoral!

i'm sure gimbo has that saved in a template somewhere! oh he's a QLD member... copy, paste.

I can't see why a diff swap when done properly would be illegal + you get upgraded brakes, axles, bearings. but you will lose diff clearance.

Keep the tyres and buy 4 new rims @ $50 each, heaps cheaper and more reliable the bundera option.

I can see why you would do that though

Seriously, the rules regarding diff swaps in qld don't seem as restrictive as some may speculate. Your legal tyres size and track width is then based on the axle donor vehicle as I understand the rules. You of course must meet all the other rules in doing such (tyres covered, minimum ground clearance, suspension height change etc etc etc). But you can work with this, and build something that would be very interesting, and still legal. The only thing that is 100% bum is the concrete rigidity on tyre size change

But really you should talk to a few certifiers, each one of them has a slightly different view on the rules, and may interpret them differently.

Surprisingly enough when I say something I make sure, most times, I know what I'm talking about. I researched all of this about 5 years ago when we were thinking of moving to Qld and I wanted to take my Zuk up. Being as it was heavily modified I looked onto ways of getting it legal. Diff swAps was one way I looked and at the time it wasn't an option legally. So scoff all you like, by all means do your own research and come back with other info but you will notbe able torun 33s on a Suzuki even witha diff swap

If you can find a suitable donor vehicle with diffs, that can legally run 33's, you could. The laws allow it, just not all certifiers will sign off on it, because they don't have to. Probably Defender diffs or something (not really sure on a vehicle that would be suitable).
Your right in that 33's would not be legal on Hilux or bundy diffs, or on any Suzuki diffs.
From what I recall of seeing of your old Suzuki Grimbo, you could have got everything on it legal in queensland, apart from the tyres, and any extended shackles. And yes I know it technically had a diff swap also (WT from NT is a diff swap in reality and should be plated). What was really that outrageously modified about it?
So what was the part you couldn't get legal? just the tyres?
Maybe the laws have changed since 5 years ago? I dont know...

I think the qld rules are poor, but they are not as bad as some of the people on these internet sites make them out to be. As I said above tyre size is the only thing that really sucks bigtime!

New jeep wranglers come with 32's standard don't they? So dana 44's with 33's = 1" increase, possibly legal?

tyre size, RUF, 3/4 eliptic, engine transplant (although that was going to be easier to get legal in QLD than Victoria) too much combined lift with body lift, suspension lift and extended shackles and the wide track conversion as it was over the allowed increase in track width

- Tyre size: never legal
- RUF: quite easily plated
- 3/4 Eliptical: Not sure, as I've never looked into this
- engine transplant: depends on the motor I guess.
- Body lift and suspension lift are seperate. a body lift of up to 2" can be complianced through a special application process. The suspension laws are the 1/3 bumpstop rule.
- extended shackles are never legal either
- The wide track conversion can be legal. As I mentioned above, a part of the laws state that the vehicles legal track width increase is based upon the vehicle that the axles come from, so long as the wheels are covered etc.

Call Rod at One stop suzi shop in nerang

He has a LWB Zuk with Hilux Front and Bundy rear and a turbo 1.6/gti head and as far as I know its engineered in QLD!!! Ive seen paperwork to prove it!

would that car be yellow? i think i saw it for sale on ebay ages ago had 31s for on road.

i am building my ute with bundy diffs and coils it will be mod plated

to be honest its not all that hard to hilux a coily sierra. make some new lower arms and fab up a cross member front and rear to suit the uper 3rd link. use standard panhard mounts on the chassie. standard coil mounts on the rear and fab up some for the front, some shock hoops and your away. leafy transfer with gears thou you would want this anyways, and run standard shafts with spacers if you want to move the diffs. not much more in it than going spoa. as for legalities qld sucks the big one. thou with mine as modified as it was hilux diffs and 2 inch wheelspacers and what not, no one ever asked any question in nsw. and i never had it engineered.

im getting w/t sierra diffs signed off on an LJ so i cant see why you couldnt get lux diffs or bundy diffs signed off. SPOA is illegal up here and cannot be signed off though.

Do you happen to have a link for this HS?
