Outer Limits 4x4 Board

anyone that could help out with the following info would be good....

What is a good price for a pair? what ratios did they come out with?
Possibly 4.6?

can they handle 42s with little problems in CV strength?

also compared to GQ diffs, how much wider are they?

cheers guys.

Screwy

GU diffs are approx 30mm wider than GQ

ratios are 4.1 in 4.2 diesels,
4.6 in 2.8 turbo diesels,
i believe 3.9 or 3.5 in petrols
and 4.3 in the 3L turbos if my memory is correct,

mate my pair of 4.625's cost 3k from gold coast 4x4 wreckers. i am running 38's on mine. the prob is that with a 38 they turn too much and hit on the arms so you will need to adjust the steering stops. that said they are far less likely to break if they are turning less

cheers bru

I would be running 42 inch plus tyres on them and flipped rims so i doubt the tyres will hit on anything

Will they hold up to 42s?

mate i run 4" backspace beadlocks on 10" rims. driving style has more to do with breaking stuff at a 42" level. even a mog diff will break with the right hp and lock steering. the way i see it they are strong enough. i wouldn't run 4.88 as they are too weak in the pinion but 4.6 should be ok but are rare as they came outta the 2.8 99 gu's. maybe get the bigger rear diff from some 3lt and the utes as i have seen a few rear axles break. they really are massive but the grade of steel isn't the best. you don't have too many options as far as cheap axles go for 42's so gu are prob the best bet. the gq ones are not much weaker apart from the cv's, but note they have a 2m larger turning circle.

GU CVs are far stronger than GQ CVs arent they? cause MQ and GQ cvs are the apart from spline count......

I want to upgrade CV strength more than anything.....

they are about 30% stronger i have been told. you would be doing well to break one, many competiors don't carry spares in the obc. a decent gq cv like a haultech or a modded to suit toyota longfield should be gu strong (or posibly stronger) but would cost much the same and i prefer std factory for easy part exchange or emergence swap during race etc

cheezy was running 42,s on GU,s with 300kw !!!! & lotsa gearing !!!!

good enough for me

kym bolton broke one in the obc in 04, 36's. driving style is more important. also cheesy was making his own cv's at the time so one would assume his were modded

I used to break a GQ cv (new) every outing without fail then went to genuine 4.6 ratio and GU front fiff and have not broken a thing. The GU cv is 2cms bigger than a GQ gv.

good stuff.....

MQ CVs are the same as GQ CVS, and im popping them farely regularly...... i want to upgrade without the huge cost of danas etc etc...

you can't go wrong really. swap to coils at the same time too

Nah coils can wait, i have enough flex not to justify wasting my money... ill go air shocks with those diffs in the rear, and keep leave front

But this will be more than likely on the next rig
