toughest gq cv's

Joined: 04 Dec 2005 Location: cessnock

Ok I know search. But having read all i can on heat treating etc I want to know who uses what, and what works and what still breaks? I have read about yuri cv's and haultech, which are better? Is there better on the market? I have heard of putting hilux lonfields in but don't know much about that? And without going to GU front diff.
So I guess I asking for an ultimate cv for a gq front diff?

Thanks Dave

We've got Yuri CV's in the buggy, seem to hold up pretty damn well. You can get him at www.yuri4x4.com

Cheezy was talking about Chromo CV's the other day. You'll get him on 03 9762 9032 www.cheezyracing.com.au

been told cal offroad are making the strongest gq cv on the market. Apparently will NOT break 40" or less. Cv and axle made from 300m(?c) chromoly

What about the ones that have a reinforcing ring around the cone?

They are better than std but not as good as a custom cv that is machined from a higher grade alloy steel. But remember somethins gotta give, tyre spin = bigger tyre, cv breaks = stronger cv, inner axle breakes = stronger axle, diff breaks ect.
I'm happy on 37" tyes n If some one will show me a cv that will handle it I'll buy them. Most times the stronger cv's as a pair are as dear as a gu front, so if they were affordable it would be better, also some sort of guarantee.

That's a big claim "worlds stongest cv". Longfields might beg to differ, but they don't make gq.

could you please explain why nissan guys think GU diffs are best almost unbreakable upgrade???

they have smaller inner axles than STOCK toyota's, and a welded/ringed cv is nearly as strong as the inner axle. so the next thing to break is the inner axle.

it would be cheaper and easier to put in a toyota 60 series diff with chromoly 30 spline axles and at least it would be STRONG!! YEAH yeah i know everyone is making chromoly axles for nissans blablabla - but where are they????? i have been waiting patiantly for them "to be shipped" for the last 4 weeks. I can get longfields air freighted in under 48hrs!!!

gu diffs are good, not unbreakable but very strong. I have seen more 60 series inner axles break then nissans. Most times the toyota inner axle crack though the circlip groove.
Can you please explain why people with 80 sreies are putting GU front diffs in there cruisers if the toyota diffs are better. GU have better brakes then GQ n are a bolt in exchange item n also not much more then a pair of longfeilds, the cv's are not that dear to replace n come with a inner axle. Nissan manuel hubs are stronger then the toyota hubs aswell, 80 series break hubs more often then cv's.
The work involved to fit a 60 series diff is not really worth it for what you gain compared to a bolt in replacement with all parts off the shelf n readily available.

as stated, if you are serious enough to want a strong fron end then why not go to the effort of doing it properly.

$1500-2000 - GU diff
$1200 air locker
new drag link and heavy duty tie rods.(still crap low steer)
$2800-$3000 doing it all yourself (which if you aren't able to do then how are you going to ever fix it out on the trail??? ring your mechanic??)

$300-$400 60 series diff
$800-$900 30 spline longfields
$100-$120 chromoly hub gears
$10 grd 12 cap screws for the hubs
$1200 air locker
$400 for new mounts to suit
$500 chromoly high steer arms
new drag link and heavy duty tie rods. (now at least they are high steer)
$3500 for a diff that has axles nearly twice as strong as GU and hubs that are far superior, and decent steering geometry.

I am sorry i just dont get the whole GU diff thing, $500 difference is nothing when so much extra strength is available, maybe its just because its bolt on stuff, and its just a follow everyone else thing. Who cares what brand is used, gq's use toyota shocks in the front end if you lift them anyway!! Confused

as an upgrade people with a locker already dont need a new locker, dont have to spend the time fabbin mounts or using custom parts, that are not available where ever you brake it. What about tail shafts for the 60 series front conversian or brake lines. How many diff ratio's are compatable between the 2 different manufacturers?
If you are serious why not use 404's or Dyna track D60's maybe Rockwells.
As far as lifted patrols using toyota shocks, if you put a toyota shock in the front of a patrol it will bottum out n destroy the shock, if your talkin aftermarket shocks they are after market n not toyota.
Just curious what sort of engineer are you? I could make all the steer arms with tie rods for about $200 n probly $70 for all mounting plates for the 60 series conversion, If your goin to do the work yourself you dont need to buy anythin exept the materials.
If you are a engineer what sort of steel are you talkin about for steer arms n such the term " chrome moly " gets thrown around alot but most people wouldnt know chrome moly if it bit them. 4140, 4340 are not chrome moly. Free machining steel has manganese in it, it is not manganese steel.
If you want bullet proof hubs why not use S600 n get it heat treated to 57Rw n have it EDW to fit the spline? Do it properly.
Use S600 for the cv's n inner axles, spindle's, custom airlocker, they are not hard to machine, I used to machine heaps of them from hytuff.

The CalOffroad Cvs are in customs now and will be released in the next few days, These are the strongest GQ cv and axles available. all specs and details will be released at the end of this week

you may think its twice as strong but keep things simple.

I would rather have a GU diff in mine at least i know i can buy genuine parts anywhere for most of the comp work GU's are fine if your having to custom modify parts something eventually is going to brake i seriously doubt you would never brake longfields axles and more to the point if you bend the 60 series diff you have not only replace the diff but go to the added expense and time again to do new mounts.

Kimple it simple from the start, is my oponion.

if this is true - YEEEEEEHAAAAAA, i have a GQ comp truck i am helping to build and we have been hanging out for these. I have been holding back doing a D60 knuckle conversion so that i can try these bad boys!!!

so what is the realistic ETA for delivery to brisbane???
if you are using a customs broker then you should have then in 24-48hrs. hopefully they will be in by next weekend!!! armsup

It is the whole shooting match - 2 CV's, 1 short axle and 1 long axle.

They are probably too expensive for most, but they are dirt cheap for the bloke who is breaking a CV every weekend.

To give you an Idea of where the money is, there is tens of thousands of dollars into the man hours to solid model the pieces and write the CNC code to carve them up. The machine time to run them is then hideously expensive, these machines have lots of more profitable things they can be running when they aren't making birfield joints for our little hobby.
The material is expensive, think about how big a lump of cr-mo has to be to machine a CV joint out of it, plus the star and race and balls are all custom machined.
The material for the shafts is big $$ too. Then you have to pay for someone to heat and cryo the whole lot and get it packaged and sent to Australia.
10 complete sets were sacrificed for destructive testing before it was decided if it was even worthwhile to make these things Laughing

Realistically, probably only about 20 odd people in Australia will end up running these, everyone else will just complain about breaking CV's all the time, Laughing

or keep paying for treated stockers...

In short, it's only worth making these because the European and Middle East market is so big, but I really do hope that a lot of people in aus end up running them and that they work well for them. I really like the Nissan gear, but the stock CV's are a massive, massive handicap.

Agreed but after all that there is no gauarantee that you won't break a $1000 cv and or axle like longfields do. You do get what you pay for and these sound great.

the ball bearings will be off the shelf, for whats involved with a ball bearing grinder they will be using a common size ball, the balls dont break. The machine time is not that much and material is not that dear. The program time would be the expensive part but not that dear either, remember they will make alot of these.

We made some Hytuff range rover CV's these sold for $750 each, price is dictated by what someone will pay for them.

Materials: axles $40 ea, cv $80ea, heat treatment is not as dear as people make out if you get it done as a job lot, not a 1 off. The spider could be expensive to get it ground depending how its done.
If they will put a warrenty on them then they would be worth the money.
