as the tittle says...im just asking as building my new truck and am doing quite a big lift.ive got some tyres coming from the states so just woundering if anyone is running anything over a 37 and if they got any real bad rubbing issues...??? i know 35s will go most places but this thing is been made to do more driving over rock and stuff than trail work.

Got a mate that runs 37's on his GQ. He has got good at fixing CV's and hubs. It wouldn't run them without a turbo.

Depends how much lift its going to have. the places they rub (with 35's and 37's at least) are the middle and front of the rear arches and the back of the front arches. Takes a bit of surgery but they can be run on 75mm lift. And yeah I'd def have a turbo on it if its running the td42 engine.
Shaved diffs would probably benefit you also perhaps?
Bigger than 37 would rub everywhere at a guess but never seen it.
May be a heap more work than you think.

4wd custom guide says 6'' suspension lift 2'' body lift and cut the guards

I had to trim my rear guards to run 35" simexs, 75mm spring lift & 50mm body lift still not quite enough as I put +16mm bottom trailing arms to level diff out to stop destroying rear shocks. No problems in the front.

yea i think alot comes down to the amount of lift.ive seen guys running 37inch plus in auzzie when i lived there.currently sorting 125-150mm lift,got 50mm bodylift.ive got some 38inch maxxis crawlers coming from the states on a special order.

im quite prepared to spend the money i have to on my truck,currently i know my suspension will owe me around the 6-7grand mark and also know im going to have to spend around the 4g mark on chromoly axles/cv's.

If I was doing what your doing I would lift the guard arches (inner and outer skin) to suit and maybe push them inwards a bit rather than add more lift right off the bat.

I have no body lift, 75mm spring lift and 10mm spaced rear bump-stops to stop the slight rub and 35's run easy as.

I tried to keep the center of gravity low on mine and so far its worked well.

All comes down to what you want from your truck.

Well if you are prepared to do it right and have $10k to spend on cv and suspension then you should be able to do it right. You don't need a big lift to fit big tyres.
For starters, you don't need lots of lift to make the suspension work correctly. If I was you I'd work backwards.
Start with desired goal and sort the suspension to that. ie are you going rock crawling requiring massive articulation or is it a more all round truck with a bit of everything?

So now you probably have a suspension height of around 2 to 4" above standard.

Next will be springs and shocks but if i was you with the budget you're talking then I'd fit a 2.5 coil over and a hydraulic bumpstop at each corner. If the budget is big enough then I'd strecth to a second shock but that will only really be needed if you plan on high speed work.

You will need get new shock mounts etc made front and rear and since fitting them in the rear will require holes in the floor you may as well turn it into a ute.

Now that the truck will be able to utilise the tyres CUT THE GUARDS to fit the tyres and the ride hieght!

Cromo CV's are $2k so you have $8k for the suspension. FOA coilovers with twin springs and bumpstops will cost around $5k so $3 to fit it all and cert it.
So with $3k to fit it I'd do a 4 link rear end and really make that work as well.

Or you can just spend $2k on a cheap suspension lift, $2k on CV's and cut the guards a bit.

Have a look at the 'big lift aholics' thread on Outerlimits for ideas on how to make it look cool but handle like shite!

im building the truck to flex and drive over car sized rocks.i have been looking into the FOA 18inch shock to be fitted to the rear,90% of the work is been done by myself and the rest will be done at local workshops who my mates own and run so cost is quite cheap labour wise and i have access to my own workshop / hoist in the workshop i run.

at this point i am lifting the truck to the same height that trucks of the same make in auz are that are doing the same type of work mine will be doing once complete because a 2-4inch lift just isnt going to get me through any of the places im wanting to go play.as far as inner guard cutting goes we have looked into this but will only be done if i get bad rubbing.

from building a number of race/drift and show cars now i know that spending the money once is best instead of just going with something because it is going to be abit cheaper...and then you end up spending tiwce as much because it doesnt work as good as you would like it to...so at this point im thinking that 20-22k should build me the truck i want and this is including the cost of buying it also...i have also been talking to a number of guys who do cert work and also the vehicle certing nz in wellington and so far they are happy with my truck as it is all been done right so will all be cert''d,wof'd,reg'd and able to drive on the road.

I'm also fitting 18" FOA as value for money they'd be hard to beat. From what you've just said it sounds like you're done your homework the only point I'd make is the lower the centre of gravity the better. Obviously with big rocks it becomes a compromise due to wanting high ramp over.

If you do your homework and work with an engineer, it is amazing what you can get certified! It makes me laugh when people have problem certing vehicles as it is normal because they cut corners. My truck is basically a spaceframe and has the coilovers mounted onto the trailing arms and yet it can be certified (with a bit of stuffing around) so yours should be fairly straight foward. The key is to be up front with why something is done. The guy I use is pretty cruisey about what I'm building as he knows it is for a purpose and I want it to be safe. Yet I know a lot of guys who can't get a simple lowering job certified.

You're so right about doing it once and spending a bit more saves a lot of money!

Sounds like a cool project so keep us informed!

like this set up maybe

MMmmmm tuff truck...cant wait to be there again next year...!!!

the tyres that truck is running is what i was looking at 1st off but the fact the 40's only come in 17inch rim size puts my off,even been in the mag and tyre trade im put off by the fact i cant get them in a 15-16inch rim size...so thats why Maxxis are bringing in a special order of 38inch creepy crawlers for me.

im trying to keep a full bodied truck at the moment as i still want to be able to load it with mates and be able to use it for normal everyday driving if i have to.i would love to have a truck like the one pictured for just crawling around in river rocks etc but like i said still want to be able to use it for other things also...the only thing i could see happening later on to the body will be a external rollcage

was good to see it to be the first threw the mud run at night that others drove to the start and called the end of their turn

Did you ever get your 38's skidtoy?
