View Full Version : Bullet Proof, 4340 Chromoly 28 Spline CV Shaft Outers

12-04-2012, 01:55 PM
Ok I have been working with an engineer at RCV axles on a solution to some of our problems. Everyone seems to break there axles at the outer hub. I know Ive done it, 4 times. I know Dave has, and Doug has, and probably Anthony Arnold, and many Many others. This is the weak point in our cv setup. Drive shaft shop axles are thousands of dollars and no one wants to do that. So heres our option, a direct bolt on,4340 Chromoly 28 spline outer. These will have a life time warranty! This will allow us to have DSS strength on the outers, with out custom or mustang hubs. These will work with all factory rear end components.

This group buy is for the outer hubs ONLY. If someone finds the next weak link RCV will sell us differential flanges if anyone is interested to switch the inboard over to Porsche 930 joints. Custom axle bars are also available in 4340 and 300M any length or spline count. They are also willing to work on new outer hubs for us, You know, those discontinued parts that get ruined by bad wheel bearings!!!!!

Now we can take NOS ford parts or Autozone axles and beef them up to withstand probably anything our 3.8 can dish out.

Heres the pics.

And the Price Break down. Currently they have 42 in stock.

1-9 $195.00/ea
10-20 $175.00/ea
21-50 $155.00/ea

Im working with them now on how they would like to handle the order, shipping them all to me for example, or shipping to individual buyers.


That means this group buy hasnt started yet, Im leaving it up to you guys to decide a start and ending date. Maybe We can start it around Christmas and run it to the end of January. If anyone doesnt want to wait, PM me and I can set you up with the info to order a pair and have it shipped before, or separate from the group buy.

If this thread shows the interest, Ill start and Official thread with a list of names and a DUE date as soon as I figure out shipping.

EDIT, THESE WILL BE DROP SHIPPED TO THE BUYERS AT 10-15 DOLLERS SHIPPING COST PER PAIR.

I need to check with the engineer there, but I think Im going to push this back towards tax return time, maybe starting in feb into march. That way everyone can pinch pennies to upgrade their drive trains. Keep posting your interest tho! Just guessing by this thread so far, if everyone committed, we're at 18. Getting the last price break will be easy.

Edit, unless you guys think I shouldnt wait, in that case we can place an order right at 22 units, since we're not getting a break after that point. Edit your posts with a cash ready if you are. We may have 22 soon.

So if the outers dont break then where is the next weak point? Just curious. Do you think the inners will be the nest weak point? Dumping the clutch at 5000 RPMs :D

12-05-2012, 09:58 AM
Something is going to break next, but who knows it could be the slip yolk. Ive seen more of those break than inside cv's. At least RCV is willing to do options in case we'd break an inner or the shaft next. We could technically build a full crazy axle if need be. SO you in or out Rico!? BTW 3800rpm clutch releases on my wimpy turbo car net 1.6 60fts, no need for this 5000k rpm stuff.

More than anything, the benefit of these parts would be consistency. Aftermarket parts are often re-manufactured and of questionable quality. do you really want to find out you got a bad one in the staging line at the Shootout?

A new company making a part for the tbird that solves an actual problem, and sells it for a reasonable price is great. A relatively small price premium for a part of known quality is a win, any day of the week.

A couple of us on TCCOA were likely gonna order the DSS axles right after the new year, but this might be a better alternative.

How much for a full axle set with all the bells and whistles in 4130? In 300M?

The other guy already broke an axle and I'm planning on 6500 launches on 4.88-5.13 gears, so I know I'd be on borrowed time.

Yea I've broke 4,2 in one day so my question is, is this gonna be any stronger I've level 5s ordered with cobra 31 spline inners, but I'm not against getting a set of these I'm just curious if its gonna be any stronger

neverfastenough
12-05-2012, 01:59 PM
These are much stronger, Last I asked I believe their engineer said roughly twice as strong as stock. The factory is probably a case hardened lower carbon steel than these. These are chromoly and they're covering them under a life time warranty, they are very convinced that we wont be breaking these! Stress risers in the factory design also look to be eliminated. I know mine all broke at an obvious stress riser right where the splines start.

Robert was specifically asking if they were gonna be stronger than the DSS axles which are made out of 4340 chromoly.

RCV is an off road line, they make on road axles which are sold under the DSS name. AFAIK they are identical. The wheel hubs they want to do for us are 4340, and Im assuming these are also. I think DSS sells them as 31 spline though with new wheel hubs. These are 28 spline. Naturally more splines is stronger.

These would be weaker than dss level 5 because of the spline count, these are basically the dss 600hp ones

guitar maestro
12-05-2012, 02:25 PM
Oh ok I see. My setup is currently stock 28 spline, but I'm still interested in what a full 4340 or 300M axle set will run. Subscribed. :)

BTW, please ask if [higher] spline count alters any of the pricing while you're at it.

Im going to try to direct the guy Im talking to, to this thread. Ive been killing this guy with questions. IF you want a mean axle its going to probably be 31 spline inner also with the porsche style hub.

These stock axles have lived in very high hp supercoupes with proper use. Since they are on the ragged edge of their limit, mild wheel hop or abuse at these 400rwhp to 800rwhp levels is basically instant death. These chromoly ones are extra insurance, for a slip outta the burnout box, or the accidental poor launch etc. Nothing is designed to handle ridiculous shock loads. Therefore, in a properly setup car, especially auto. I cant see why anyone here would need 31 spine. IF you're spinning donuts in wal-mart parking lot hitting pot holes.....well nothing is bullet proof. Luckily it is no questions asked warranty, so If this happened, we're covered.

The first group buy here IS what it IS, 28 spline chromoly outers. I will try to answer custom ap questions tho. I dont want to clutter the thread with them though

12-05-2012, 03:15 PM
I'd be interested in a set of these in the spring also if funds permit.

I've already broken 6 of them at the hub. The last time 2 at once. It would be nice to eliminate that problem if at all possible. I have a set of the stockers sitting here just waiting to put them on LOL!!!

12-05-2012, 03:47 PM
The DSS level 5 outers are 33 spline with a special hub. The 33 spline hub by itself is 225-250 when I last checked.

Mike8675309
12-05-2012, 05:46 PM
correct... DSS 5 are the 31 spline inner and 33 spline outer and require a custom machined hub.

Otherwise DSS products are 31 spline inner and 28 spline outer.

what is being discussed here is the outer CV joint with integral stub shaft.

SC's have a 28 spline inner CV joint (28 splines in the side gears of the diff). Mustang Cobra's have 31 spline inner CV joints (31 splines in the side gears of the diff).
The larger inner CV joint didn't stop cobra's from shattering the outer CV joint, just like we do on the SC's. Thus DS came up with the DSS 5 product.

Mike,

DSS also makes a thunderbird (89-97) and 99 Cobra halfshaft with a 28 spline inner.

Can these guys supply a complete (direct replacment) halfshaft that compares to the DSS level 2 shaft I linked above ?

David

12-18-2012, 08:00 PM
Im sure they can, these guys machine all this stuff from 4340 billet, theres no minimum order on most stuff, just machining time. Im broke, I know many others who are broke. So if a full axle is what you guys want to do, you need to leave this thread and Ill look into it, I just dont think the interest will be there.

Say the outer is 195, the inner will be more Im sure, lets say 250, guess at 200 for the center shaft. Lets still be generous and say an axle is going to be 700bux a pop......THIS IS A TOTAL GUESS....but I bet Im close.

I was advised by a member here to not do a group by months ago. We got a good break in price so I decided to post it. I dont want a headache. So far RCV has be very nice to drop ship to you guys to keep work off me. Basically Im just keeping them updated and organizing this, they dont normally sell like this and use dealers naturally.

SOOOOOO. Is SCCoA ready to pay for a full set of axles? Definitely breaking away from 3 figure prices to 4. I think you guys should save some money for the wheel hubs we're working out. Those are the real breakthru for the community as these are obsolete. And they wont be cheap either since they are also machined from 4340 billet.

So please guys, let me know what you want to do.

Do you guys want:

1) Outters<$400
2) Outters and inners later<$1000
3) Full axle 28 spline inner and outer>$1500GUESS
4) Full axle I dont care what it costs as long as it doesnt break, I dont care what spline or what I gotta do to make it work

Corey,

Sorry...I'm not trying to muddy the water on this group buy for the outer stubs and I'm still in for two to use on my 91 SC. My only concern with buying the stub shafts, is what difficulty there may be in doing the swap, repacking the grease and resealing the boots.

I'm just looking for options other than the DSS level 2 shafts for use on my turbo car. The DSS level 2 only comes with a one year warranty, and if I could get something with equal or more strength that had a lifetime warranty I'd buy it instead of the DSS level 2 shafts. At this point I'm not interested in going to bigger spline shafts on the inner or the outer, just want the strongest stock size replacement possible.

No prob David, well stick with the outers come group buy time, and Ill look into a full 28 spline axle then for your turbo car and others who may want them. I hate to drown RCV in questions, it took me awhile to get them to think we're serious, we do drive tbirds and not mustangs.....

Hello. I joined SCCoA specifically to find out more about these outer CV shafts.
How would I go about getting the name/contact of the person you worked with at RCV Axles?.

I would like to have similar custom outer CV shafts made that will work with jaguar S-types, Lincoln LS, and DEW98 based T-birds.

The only difference between the design that you had made and what I need, is that I need a longer splined section. New outer splined shafts are no longer available for these cars.

It looks like we r gonna make another try at this group buy. :D We've got what looks like 12 people who have commited in the new thread in the group purchases section. I noticed a lot of different names in this run who are not in the new one. Come on over people, lets do this and see if we can knock the cost down!!!! :D The plan was to try to open the buy in mid Feb, but it has been delayed a bit, but could happen soon if enough people step up.

These are available simply by calling RCV and ordering. We had a group buy last year that got the price down a bit, but regular price isn't all that bad either. If you order some, be sure to ask for boots and grease to go with them because the stock boots won't work.
