Outer Limits 4x4 Board

i am toying with an idea at the moment and i would like to know what 4x4's have the longest travel ifs and what 4x4's have the strongest ifs. If i go ahead with my idea it will be gracing these pages here soon

cheers in advance flyinwall (and no project gremlin isnt going ifs)

strongest: anything but toyota

Hummer ?

nissan got a really strong IFS system do they?

Depending on what your planned use is, take a look at some of the trophy trucks setups. While not factory, they are long travel, and TOUGH.
If you could fab something like that up

Layto....

The desert racers use a setup with Porsch CVs. Strong but $$$$$.

Drool!!

No one mentioned Nissan

Mitsubishi IFS > Toyota IFS in strength.

Would prolly be worth a look. Portals too

Front IFS Diffs:
Nissan Navara IFS 7" Diff
Toyota Hilux/Prado/Cruiser 7.5" Diff
Latest model Hilux 8" Diff (but completely different from old stuff)
Pajero early ones (dunno about new ones) 8" Diff.

you talking driveline strength or suspension strength?

A late model holden IRS diff would have to be the strongest diff you could put up front, and as for suspension components youd be going full custom i would have thaught?

What are you after with this, crawling (:lol:) trails, sand racing, pre running??

Bit off topic but what exactly constitutes a pre-runner? Hear it alot in american mags/pirate.

out of the local crop the 120 series cruiser has the longest travel ifs second only to nisan gu. but aparently the diffs are week.

and the mitsubitshi late model nj onwards have strong front ends too.

*cough* gu doesn't have ifs *cough*

A Pre runner is a term relating too American off road racing, where they run the coarse prior to the race. Sice a lot of these tracks are public roads the bigger teams have slightly less strung road registered versions of their race car. There for pre running the track, Makes sence?
As far as strong irs diffs why not look at the Nissan R200 diff out of an import skyline or even a supra diff. Both of these are quiter strong and available from jap importers.
As far as the expence of Porsche CV's, take a look at an early 5 or 7 series BMW or some of the larger early 80's Mercedes. Same as the Porsche 930, but to get real strength out of them you should probably replace the brittle standard cage with a moly one.

i wasnt actually comparing my trol
my jabber has a strong front end and it seems to flex fairly well with the bumpstops trimmed.
i used to wheel with a mate that had a surf and he blew the diff in it trying to drive cabbage tree. then he buys another surf and blows the front diff up at stockton
and on Australia day we were up there and saw ANOTHER surf blow the front diff. this time we got to see some teeth and oil all over the groud.
how do you blow a diff on sand?

ive wheeled with a few surfs before and most of the owners do admit the front end isnt the strongest around but once you put a locker in them they seem to be ok.
and these guys i wheeled with only had 33s max.

o actually there was another time up the wattos that a dude had 35 by 13.5s and he blew the front diff too.
but he was giving it a few numbers all day

i'm well aware of that. but i am stating the 120 series is 2nd only to the gu for front wheel travel and not by much, wich is impresive for ifs.

i notice some of u say nisan navara front diffs are strong, i went on a trip with a 3.2 navara on 31's once and within 30 mins of driving he'd blown his front diff, and we were not going hard. not what i'd call strong.

Well I can tell you that the current Pajero IRS is the strongest set up ARB have seen for such a configuration.
9.5" and very thick C&P and 33 spline 36mm diameter axles and massive CV's.
The Prado 7.5" grenading issue is well known.
As for the front 8" Pajero high pinion purely for the crownwheel thickness (I have seen Tojo, Nissan & Jackeroo and there's no comparo).
CV's/axles are all pretty similar strengths but the Mitsi/Nissan are about 1mm diameter thicker.
In terms of steering/suspension components I would say definitely Mitsi/Nissan but I wouldn't call them particularly strong especially with over 33" tyres.
In terms of outright travel off the factory fllor definitely the newer coil sprung Toyo's/Mitsi's have the most (about 2" over torsion bar versions). Torsion bar set ups are around 5" total travel, coil springs around 7".
This is a torsion bar Paj with swaybar disconnected and chopped upper bumpstops (no ball joint spacers).

Someone has explained it for me anyway, but as said its basically a toned down slightly road friendly version the race trucks that the team use to scout the stages before the actual event

I dunno how strong they are, but ford broncos have a decent looking ifs setup at least at the glance I've had at them, the arms actually travel right back past halfway across the width of the vehicle and they cross over each other

heres a real custom ifs set up on a vit

NICE!
But it has no front diff.

just need a nice jag rear end from the states and the right ratio.

The ford's use a TTB (twin traction bar) front end.

ok to put you all out of you missery i was thinking of welding the front end up to create a sort of solid diff with loads of clearance under the pumkin and run it as you would a solid diff with coil or leaf springs. i know it sounds weird but it could be ok as i wouldn't be running huge tyres and its going to be a bit of a buggy (well its in my head as a buggy plan at the moment)

its been done.

Yer, I've read about it before. Can't remember if it was on here or Pirate, probably both.
