The Atlas becomes the next weak link. Scott Morris aka machinwave has broke about 6 atlas transfer cases since he went to his hybrid 80 axles. He supposedly has 700+ horsepower also.

I was thinking it was something in the range of near 800 ft/lbs, which is what is blowing the case apart.

Either way it goes BOOM

And here is one of Jordan Tanners RCVs from this past weekend

Yeah it's possible for sure. The only problem is it's going to get covered in mud pretty quick.

i ran ctm s in my highlighter and broke joint very ( easy ) running rcv joint with 500hp and limit ram to 7 1/2 stroke never broke yet 6 months so far need to figure tire size and weight and hp in this topic put a 42+ sticky on it and see if that ctm holds up good luck

Brian I remember talking to you about limiting the ram at 7 1/2 inches and it helping the life of the RCVs. Thanks to everyone for all the input. You guys beat on these parts enough to know whats working best.
After some research I think I will wait out the bigger RCVs and the upcoming knuckles Ive heard that were being made. I think the knuckles and C's will be out in a couple months but not sure on the RCVS . At that point I may have to run the
std RCV's but I will at least have a knuckle that will fit the larger RCVs as soon as they come out.

More axle porn,please. When are we going to see some pictures of the new 40 spline RCVs? What does a steering Tubeworxs front cost?

Branik sells 40 spline goods. :woody:

This is a testament to RCVs... For all those people who are calling them "junk" now, since TC and the Bobby/Jordan Tanner have been breaking them.

Hard to call something "junk" just because a few people with 600+hp that ride almost every weekend break them.

Aren't many of their breaks the stub shaft or inner shaft? Which has nothing to do with the joint anyway?

x2. I don't think most wheelers have any idea how hard the true rock bouncers are on parts. You got a handful of the top rock bouncers in the East busting RCVs and they are now junk and every Joe Blow now thinks they need 40 spline 14 bolt rock hybrids. Gimme a break.

Not sure who this was directed to but im assuming me since I started the thread. First of all you are right about the fact that some ppl are judging the RCVs and other parts that are breaking simply because they saw or have heard them breaking.
I wanted to hear 1st hand from the ones that are breaking them and compare them to other available products and new ones that are coming out. And I appreciate all the input and advice that has been givin. As far as a hybrid 14 ?? why not? They are easily available, cheap and strong as hell. I contemplated on a 14 bolt years ago but built pair of hybrid nines instead . They are for sale on Pirate and have only been out twice. Since these axles were built I have broke plenty 35 spline shafts in other axles. I am currently wanting rear steer and selling them as a pair and figured Id beef up more on this next set of axles now that new products are available. I wont ever spend the $$ on custom centers again not when I can go pick up a 14 bolt for 50 bucks. So if that makes me a Joe Blow like everyone else ...so be it. here ya go...

Comment wasn't directed at anyone in particular.

Here's something else to consider. Woodlee runs 4340 35 spline Spidertrax shafts in front and rear steering 14 bolts with 39 stickies full of water and 530hp. He's also raced KOH multiple times. Most people would agree he is hard on his ****. To date, he's only broken two shafts. Conventional wisdom says they should not be as strong.

No question that the spidertrax axles are strong, only problem is you have to run all spidertrax outers ... If your building a custom axle that is not such a big deal

Why is that? Spider will make them any length or spline.

Example of a Spider order.

The joints won't fit in a kingpin style axle . Have to run spidertrax inner and outer knuckles

Spidertrax shafts are some of the best out there. I would have ran them if they would have fit in my 60.

redneckengineered · Nov 3, 2011

If their 4340 shafts are that good wonder how the 300m ones are? It's pretty gay they don't make them to fit in a normal sized 60 knuckle. They'd sell a **** ton more shafts I bet.

I agree - I would love to have them. I just hate the clicking BS from the RCV shafts

So what is the advantage to running their shafts? Are ppl. breaking the cross/body of the ctms? The 1550 has the same size caps as the 1480 which I would figure that would be the weak link.
As far as building custom ur right it wouldnt matter about size then. The knuckles I am looking at are designed to have upper and lower kingpins on bearings. The face will be machined to accept a rockwell spindle.
Or a adapter can be purchased/made to run a standard size spindle. The knuckles would then make it where you would have endless options. Rockwell spindles super 8 outers with OEM 2", violators and neck the inners to 40 spline.
Now the joint is not the weak link. They are waiting on RCV for the specs on their bigger CV. This would allow you to run anything from 35 spline to 2" . I just have a hard time justifying what CTM wants for their 40 spline 300m and still have the same size joint and compared to these other options...My end decision will prob revolve around the best "bang"(kinda ironic choice of words).. for the buck. I havnt sold my nines yet and not planning getting started on this till after the first of the year so I have time to ponder on it.
ON other note If someone knows whos knuckle Im talking about you can let the cat outta the bag instead of me because I know how some ppl are that are building new stuff.

1550 vs 1480

Too bad Sunray it's around anymore. Their 1610 axles are still pretty pimp IMO!!! They'ed need to be updated to newer materials and possibly bigger sizes but the streght would be out of this world with all the newer center sections that are out.

Anyone know if Oneal still has Jim's old sunray buggy??

98sierra · Nov 3, 2011

what about the custom 7ton face loading rocks that monster trucks use?

YOUNG · Nov 3, 2011

C103's + 2" Ouversons + Wicked Six hubs = the lighest and stongest axle. OR the same set-up with 2" Ouverson inners and 40 spline outers with 14 bolt hubs is even lighter, just with a smaller outter shaft.

Just my 2 cents.
