Outer Limits 4x4 Board

trying to decide on diffs for buggy and am looking at either GU, built dana 44 or dana 60s but cannot make up my mind so any help would be great. i am leaning towards GU but would like to know strength differences.

cheers

gu's surely there more common then a the dana's and therefore cheaper to mod.

yeah stu i agree on them being more common thats why i am heading towards these. what are the strengh differences between the 2 and is it worth the extra cost of one over the other?

there was a thread on here a while ago, i searched for it but couldnt find it. One of the replys was from stragerover (im preety sure it was anyway), it gave the specs on each diff and on paper the GU diffs are the one to buy (H260 rear). im not sure of which models came with the H260, but i can tell you leaf sprung rear diffs are all H260 and full floating. some 3L tubo diesels got them too. i have no spec on the dana for comparison though.........

good luck with the buggy

dana 60's if you have the choice.

why settle for anything less??

ok, i read through some more threads on this (its bugging me now) looks to be that a nissan rear is stronger than a d60, but a d60 front???? (is that right) is better

Yeah, the GU is the go!

Who are you farken kidding.

Stock Dana 60 you could wheel all season in WEROCK and not break them, do that with a GU nissan and you'd be lucky to finish a few stages.

I wouldn't even be comparing the two!!!!

Not saying the D60`s aren`t any good but cheezy mav runs GU diffs and even though we tried to break them we never did. At TTC05 the rear pinion only broke because the broken controll arm let the diff rotate to the point where the tail shaft uni was locked. Even a D60 would break a pinion in this case. We also never broke a CV. We also tried this many times and with 42`s aired down to about 2, his chev singing big time at about 7500rpm and slamming the side walls in to a rock bigger then the 42`s over and over and over again. The tyre was getting traction as it hit the rock and the tyre would twist up on the rim untill it couldn`t twist anymore then it would let got of the byte it had. If I hadn`t of see this with my own eyes would have never said that GU diffs are strong. I think you`d be very surprised at how strong they are POS.

Yes a built D60 would be WAY stronger but as far as stock goes I don`t think they`d walk all over a GU diff.

ok, from the way i see it d60's have more aftermarket gear than any other diff(in the USA)

i have a sals 8ha in the rear of my def110, these are very similar to a d60, they have a cast centre section with the axle tubes inserted into this.

i don't know much about the gu's but if they are like a rover/lux diff they would be easier to laminate.

does anyone make bigger axles out of 300m etc for nissans. a cromo cv for them would also be good.

it would be good if more guys in oz ran the gu's to open up the aftermarket gear for them. as building up a comp 60, though proven, would be costly

but hey i'm still on 32's so my sals will be just fine
serg

Im with the GU for availability and weight(light i mean), and they are strong, I think they would be fine if the centre was shaved and you didnt go over the top with tyre size.

Don't know enough about the dana's but you are kidding right You don't think a GU diff (be it front or rear) would last a few stages in WEROCK or similar

I really hope you are only having a go at serting people up Adrian which I know you do do. Because if you do truely belive this then you have just lost alot of credit in my book. Mainly with the lucky to finish a few stages line. Shit I`m going to be running GQ diffs under my buggy and they are weaker then the GU diffs, so what are we going to bet that I can finish more then a few stages on GQ diffs

If you are gonna go danas 60's... Go the Hi-Pinion Rockcrusher Dana 60's . Whats money..

Go the GU's man.. As guts was saying... After watching mr. cheeseman drive that mav of his at a few comps on 42's !!!! I can attest to the strength of these diffs.

There was a thread here a few months ago that had a picture comparison of a dana 60 v gu v 80 series axles and then the last 2 had cv's compared.
I have searched and can't find it for the life of me...

He will only be kidding Dave............surely. If not then he does not have the knowledge that I thought he had. I'm sure even Sam and Tony would agree that it is very possible to compete at WEROCK and the likes on GQ diffs let alone GU diffs................if not Adrian then how do those certain people do it on anything less then a dana 60..............

Agreed 100%. Shit he does it on 60 series diffs, maybe its just got to have 60 in it to be good enough to finsh a few stages of werock

Guts wrote: Shit he does it on 60 series diffs,

As does Tom. You are right..............just needs to have 60 in there somewhere................so Dave ditch the idea of GQ diffs and don't stuff around with GU diffs............................


















Go straight to the G60 patrol diffs

A G60 rear diff runs a simalar sized centre to a GU does it? I don`t know Nissan stuff.

Firstly, I know Jack Sheet about these bits. But I was under the impression that the GU, despite having a big CV, the outer axle was the same as any other Toy/Nissan outer, and probably ultimately the limiting factor for that axle rather than the inners, actual CV or CW/P. How does this compare to the D60?

LOL! It's only somebody elses money. Get a Rangie axle.

i know on paper the GU diffs are similar in size to D60 etc, but how do they compare materials wise?

Who knows

too much speculation/advertising propaganda

no actual tests

GO THE MIGHTY MQ'S

Yes MQ

they dont handle 70kg of michillin and GU rim

still cool though

GU's are just about to take a BIG jump in after market bits,
BIG axles, BIG uni's ect ect.
D60's are strong cos of the after market bits you can get.
To date the Dana is stronger, but things are about to change.
In the new year we will have all the good bits for the GU for sale.

Until sombody can fit a 35 spline axle through into a nissan hub a nissan axle will never be anywhere as strong as a half built dana 60.

A nissan GU front axle has a very small stub shaft and I dont care who reckons what about how hard they drive. If you got a GU front axle and you carnt break the small stub shaft then you arnt trying very hard. A GU stub is something like 31 spline and 1.31in diameter - which is tiny compared to dana 60 stuff.

Sam

OK i was elaborating the example of the GU's been only able to last a few stages. They would be lucky to finish one stage!

BUT the question is asking in a arse about way what is stronger!

And the fact is a STOCK Dana 60 is stronger than a stock GU.

Thats a Fact, no if and or buts.

If you were to start a season with Stock Dana 60 gear then you would more than likely complete all 5 rounds of WEROCK (just using that as an example). If you attempted this with Gu's than i would be not as confident.

No point squabling over "he said this and he said that" at the end of the day Dana 60 is stronger than GU.

Also BIG GQ if i said that 60 series diffs are stronger than GQ i am sure we wouldn't hear the end of it, surely nothing could be better than Nissan Diffs.

But hey beleive what you want, if you honestly want to believe that GU nissans are stronger than a Dana 60 than thats your opinion. I am not bagging GU diffs just stating that Dana 60's are stronger.

are these the same diffs his buggy ran at ozrock?

if so i heard snap crackle pop a couple of times, on a lighter buggy without the "big" motor pushing them

Put it this way. You give me a rig with a GU front axle for 10 minutes and I bet I can break a CV. Bind the front tyre in a hole, turn the steering wheel to full lock and drop the clutch at max revs in reverse and I reckon it will break.

If I gave you the same rig with a built dana 60 in the front I dont think you would break it in a year. A built dana 60 is just that much stronger.

Just check out the US rockcrawling guys with the dana 60 front axles with CTM joints and CTM 300m 35 spline shafts. These guys wheel the crap out of their rigs all year at competitions and wheel even harder in between comps and never break all year. They also have over 150kg of lead shot in each front tyre and they still dont break.

So what size will the outer stub shaft be?? Carnt see that you can go any bigger than the stock 31 spline through the GU splindle.

Can i ask what the lead shot is for?
&
How does it work?

Same as water in the tyres. Keep the weight down low
