Outer Limits 4x4 Board

Hey,

Just wondering how most of the top competitive trucks are setup for winch challenge and outback challenge type events.
I have a good handle on buggies and tuff truck type mods but not too sure on higher speed events.

Looking for things like:

- Diff ratios?
- Selectable or auto-lockers?
- Auto or manual transmission?
- transfer case gearing?
- rear disconnect useful?
- Suspension setup?
- Vague idea of power levels?
- Winch modifications?
- etc.

Any help appreciated.

(obviously dependent on car) 4.3-4.8
Selectable lockers (maybe auto in rear)
traditionally manuals but built autos becoming very popular
std transfer gearing seems to be the go
never seen a rear disconnect on a winch truck
suspension - strength, geometry, damping are more important that max flex
100kw-600kw
winch - dependent on class - twin motor highmount w/widened drum and air freespool is very popular - 6hp hi-mount at the very least. A few hydrauliuc and PTO's getting around too and becoming more popular.

that is all

Thanks for that.
So no ones running things like an atlas, klune, stak?

Wonder what the weight difference between an atlas/klune/stak and a GQ/GU transfer is?

I'd think that in many cases the advantage you'd have with a swb/mwb Jeep making some reasonable power would be that you'd weigh in a fair way less than most GQ's. Same spec winch and 20-30% less weight

rob marshalls new GU runs an atlas.... that or a stak. and people are pushing further than 600hp in some cars too. most run 4.6 diffs (as they are all nissans
