The driveshaft shop mentions using modified Porsche 108mm inner CVs on their MR2 axles. This could be what CRW and ATS are doing.
My mechanic's drives haft guy thought they looked like Porsche parts

"we found a different approach to making stronger CV joints somewhat by accident."

To me that sounds like they found another CV cage from another vehicle that happen to fit and is a beefier part. When there discussion started highlighting secondhand parts, I was wondering if they were just cryotreating stock cages.

On that topic, I should've also included this sentence quoted from CRW/Josh:
"our CV joints are OEM parts but not everything in the CV joint can be purchased that exact way except when we make them that way.... not just a off the shelf item by any stretch."

The beefier cages might be from another OEM vehicle as you suggested, but maybe the cages alone wouldn't be available off-the-shelf for purchase (from whichever OEM it happens to be). I'm just guessing of course.

As mentioned in my own build thread, I also ordered some CRW heavy duty inner CV joints very recently. I wasn't sure if I would ever bother, but a broken CV joint can cause serious damage to other things (eg. transmission case) as it flops around. Also, I now have a torn CV boot anyway so this is a good chance to combine the labour cost. I'll post an update when I receive the CRW kit in the next few days.

Something else that may be of interest...I just found this thread on MR2OC which compares the ATS and CRW upgraded CV joints:
http://www.mr2oc.com/showthread.php?t=464887
In that thread, ATS and CRW both replied directly with their own comments.

ATS said this (quote):
"The ATS [joints] are custom made from chrome moly steel and are dramatically stronger. I'm not going to bad mouth CRW. CRW are cheaper and they are a good joint. ATS are more expensive and they are the strongest you can buy."

CRW said this (quote):
"ATS went the route of having a chromoly inner race made to accomodate the larger chromoly race needed to hold the power. they did a great job doing so. we found a different approach to making stronger CV joints somewhat by accident. in the end were able to get a more complete package to the end user for a competitive price. i have customers ask all the time which is better... CRW or ATS and the answer is both are great. both sets of CV joint upgrades have their pros and cons but at the end of the day the customer can't go wrong either way they choose."

NOTE: Both the CRW and ATS CV joints have thicker cages, which is the most important thing, and the reason why both solutions are stronger than stock.

Hi Peter,

Mine came in as new condition as new CV's (not just cages) and bolted up as normal onto the driveshafts.

I have installed cages by themselves and they came in a box by themselves (well that is what i was given) and being slightly larger they were harder to install but went in ok.

Personally i would always go the full replacements rather than just the cages made from better materials. If you get stuck a driveshaft shop will install them in minutes.

If there is a chance of getting your money back i would, you should not have used cages that are being sold as an upgraded replacement item.

I'm curious to know what didn't quite fit. The CRW ones I had fit perfectly as a kit, I just wish I got a bit more grease with it.

No problems with fitment. Just that they appeared second hand with pieces of old gasket stuck to them

Kameleon and I bought a pair of the CRW HD Axle kits.

My mechanic didn't complain about the installation and they didn't break with 320KW so they are all good as far as i'm concerned :)

We bought ours in June 2008 tho so maybe the design or components have changed? From memory ours looked like a full drop in replacement joint which my mechanics driveshaft guy thought looked like a Porsche part???

Mine are full frop in replacement. My concern is that thgey look decidedly second hand with pieces of old gasket stuck on them. No fitting problems. I just expected them to be new parts (or cleaned up at least as no advers make any mention of second hand or remanufactured)

The bearings weren't correct on an ATS one that was delivered here. They would simply fall out.

What sort of 'fitment' issues? I had ATS racing items in my car and installed them in a few cars. Far from straight forward install, infact, very painful to get them installed correctly. The only component that is any different to standard in any of these kits is the bearing cage.

Well a few friends of mine ordered the ats & had problems with fitment. Ended up having them sent back for replacement.

Can DeltaV or someone make local quality versions.

I think ATS make them too. Maybe they do it differently to CRW.

I grabbed a whole upgrade which included the cage, bearings and outer housing. All looked pretty new to me. (This was the the inner CV's).

I agree, they do look pretty identical to the standard CV's, so they must be a different alloy to give them the strength. Mine certainly didn't have any gaskets half attached to them.

Cheers.

Yes. I got the whole package too. Sourced direct from Chico Race Works in the USA. As well as pieces of gasket there were some quite hefty "hammer" marks that looked they may have been applied when assembling the cages. These are definitely second hand or "remanufactured" as I will probably be told from the supplier

*Note: this does require the return of your old axle shafts for rebuilding to avoid a core charge.
So that makes sense they're not brand new...

I am talking only about the axle cages, not axles. I think think the koracing advert is for when you may require the new cages to be fitted for you
