Dana 60 CVs are here!!! with PIX!!!

[spencurai]

These things are frickin huge...and they have an interesting story behind them....

In russia they don't use U-joints on their military vehicles, everything is CVs. My buddy Yuri Vovchancin from down the street is ex military and noticed us working on the rigs one night. He stopped in drunk as usual and asked why we used U-joints still. I didn't know what to tell him and he said he had a surprise for us. I didn't see him for a couple weeks so I thought it was just one of his drunken ramblings until he showed up last night with a crate in his pickup. We popped it and found a bunch of these puppies.



check out the polish on these things!!!


and lo and behold...they didn't fit....



so we laughed at him and told him to piss off but he said to pull apart the knuckle and see if they fit....

since we had it down to the kunckle anyway,



it fits right in and works lock to lock...



amazingly it was 35 spline and fit a dana 60 drive flange like a dream...



compared to a spicer unit...these things are huge.




So my buddy told us that the KGB was going to have him killed because he was exporting top secret dana 60 CVs from russia so we have to keep the crate load of them for our own personal use until he can kill the leader of the rogue KGB group and free the world of the alien infestations with his super laser ray gun....


JUST KIDDING PEOPLE....THESE ARE THE NEW 60 CVS WE ARE TESTING!!

We didn't get them from russia....and my buddy yuri didn't come over...he was vaporized in a weather baloon accident last year....

We are testing these CVs. We only have three sets but they are blingin!!! They are machined out of 1 pice billet 300m and the inners are also 300M.

WE ARE NOT SELLING THESE....YET but when we do, there will be some yellow star action goin on but as of now, they are just in R&D.....so wipe the drool and stupid looks off your faces!!

Lets see under the ugly green cap. Is it just a giant birfield?????

the cap is pressed on...we tried to get it off...trust me!!!

We are testing the CV right now in the vehicle. It has been destructive tested in straight line and full turn.....numbers coming soon!!

I hesitate to call it a birfield because we cant get the cap off without damage...but from what I can see through the hole, it just looks like a typical CV/birf but enormous and built out of 300M!!!

What's the advantage? Besides 300m, why a CV?

No ears to bend and twist? I thought CVs sucked?

Sweet, post more picsof the inside if you can. I would like to see some numbers too. Very interesting. Hopefully they work out good.

one obvious advantage is turning...as a u-joint starts to approach its limit, it starts to bind causing jerky motions. These jerky motions contribute to failure of the u-joint. The CV is smooth throughout turning.

CVs get into danger as the balls try to climb out of the assembly as it approaches its limit. The first thing we are going to do is plop a tire in am undercut at full lock and hammer it to see if we can break it.

There are some in the toyota community that belive super birfs are better than u-joints of a comparable size....these are similar but absolutely enormous. Andy Holm sent a 60 inner C and knuckle into the maunfacturer so they could fit absolutely the most metal in that space as posssible to ensure durability....we have o REAL WORLD experience with these, only basic bench destructive testing but stay tuned in the upcoming weeks.

[Old Scout]

These would be bitchn in a Rover because of the full time case.

[Outshined]

I'm excited, those look seriously beefy. Keep the info coming!

[UGET IT]

Hmmm

[HandBuilt]

Who built them and how much?

What's the inner shaft spline and size?

Is it possible to get some drawings of overall size (for NON-Dana 60 apps)?

thanks. that's really freaking cool.

U-joints are nothing like having bind in your drivetrain before you even hit an obsticle. Also the little tiny toyota birfields are doing some amazing things without exotic metals, imagine what these big ass chunks of 300M will do!

[4x4 Pete]

They look a little pricey.

[camo]

for years i have been discussing this exact idea with sany cone.

sandy swears that a cv joint is stronger that a ujoint for this aplication. the main benifit is the constant velocity. ( as the name implies ) when power is applied and the wheel is turned there is no acceleration / decelaration like with a ujoint.

most people will think of toyota birfs and assume that this idea will not be as strong but as long as the proper materials and heat treated correctly and each part is adaquate size then i belive these will out perform a ujoint in longevity, and will give the high performance minded competion guys and advantage because the tire will be rotating at a constant speed while turning. that should translate to being able to turn very perciesly and controled in competion situations.

props to whom ever spentthe time and money bringing these to market.



any chance they will do a 300m toyota joint ?

[Bigger Valves]

they look fantastic. pricey definitely, but i can see them being bad ass. i think the lead and lag (binding) that comes inherently with ujoints is what causes lots of failures so cv's make lots of sense. it's like the double cardon steering joints in heavy equipment front axles. i imagine they're going to be sweet considering how strong regular little toy birfs are becoming.. any estimate on wallet damage?

[90TOYPU]

Dang SMOKEY!

[Weasel]

Yep, CV are better then U joints as long as you can keep grease in them.

Anyways why are you using 300M? It's a waste IMO. 4340 could be used. It would have similar strength and would be cheaper. There is no need for 300M, except it's cool to say.

I like them.

Owe common, why bother to design a part right and use an appropriate material, F it, just make it out of 300M and call it good.

Just kidding, I agree with you 100%, I seem to have been saying this quite often lately, besides quit using up all the 300M, sometimes it is hard to get, and it doesnt help when people make everything out of it.

Regardless, that is truely bad ass, It is about time.

[DEnd]

It would suck having to take the knuckle off if one of those broke. But then agian its not like taking off a knuckle is really all that hard... might actually be faster than taking off the Hub and spindle.

[steve gerstner]

This is the same setup on the dana 70 front with convel CV's, the steering kunckle must be removed to install the CV, nothing new - dana produced these from 1978 to 1992. steve differential eng. inc.

[BayAreaWheeler]

would i be able to use these as a dana70 tracta-joint replacement\spare??????

I'm very curious about that too but If i were to guess i would say around 5 grand. I think i'll stick with my superiors and Ctm's. Those look sweet though and if a dinky little birf can hold up to 37's i can only imagine the overkill of these.

Vaporized?? A body can just do that? Vaporize?
















sorry i couldn't resist
