    I have heard rumors or a new super joint at the Sema show, anybody know anything about this. What about spicers new joint, is it truly stronger?

    Thanks

    Is this one of those "if you have to ask its too much" kinda places? I bet they have a fat pricetag! Have you inquired about pricing?

    Spicers new joint, the 5-760x is said to be 20-30% stronger. There are plenty of guys on the POR board who have tried to break them w/o success yet. They all agree they are much stronger than the 5-297x's. I have ordered 2 sets from Jess at High Angle Driveline. $22 each.

    They are like $150 each.... all the new beefier u-joints that are coming out are spendy. But they come with warrentys if they blow they will replace them. So really if you pay $25 for a spicer, it's like buying 6 of them.... if you don't bust u joints much, then it's a waste. If you do then you might consider this. However if you are blowing u-joints like crazy then something is wrong that needs to be looked at. Plus instead of the joint blowing which saves the shaft... it may now tear up the shaft.... so it's really a question of is it worth it, which to me no, if I am not gonna buy molly shafts (which would hold a joint blowing supposidly), which again are a small fortune.... it adds up quick, but could be fun if you are looking for something different...

    Sweet! I was hoping he'd have those soon, didn't know he did quite yet. I know he was working on some that didn't make it (blew). I might have to drive myself up there to get a set! [​IMG]

    I have read about the spicers, actually what I found was people dis agreeing about them. Nobody could decide about them yet. The people that have run them say they seem to be stronger than the old spicers.

    I will check out the others. On them saving the axle, thats exactly why I want stronger ones. If you blow one your going to mangle your yokes on the axles if you dont have either the Warn or Moser shafts and even if you do they still sometimes get destroyed (ask Keith).

    Thanks

    Yeah but that %20-30% increase in strength paired with the stronger shafts probably has you in stock D60 strength range for $400 or less. Might be worth the expense seeing as how going to a D60 is a easy $1200 on average.
    Hard call.

    Only problem is, nobody can say for sure. If they are truly that much stronger I will stick with what I have and probably get some Moser or Warn shafts. Gonna have to wait and see though.

    Are the U-joints Spicer pieces, or are they High-Angle (Jess) pieces?

    Is it the U-joint without the needles, what-ever happend to those?

    What are they saying? (This is news to me, On the Spicer joints)

    The new Spicer 5-760X u-joint and a set of 'molly shafts sounds like a pretty strong combo to me.

    They are spicer pieces as far as I know.... I know Jess was trying to come up with some and I was waiting around hoping he'd get them made soon. But he said something about they didn't work out quite right so it was back to the drawing board.... I figure until then I will get spicer ones and see what happens....

    I was wondering about the strength.... because I was thinking they'd be really strong when combined together (the beefer joints &amp; molly shafts).... but when I asked about if it was approaching stock dana 60 strength I was told never could happen and it was a nice thought but whatever.... if it could be in that range then I seriously would like to tinker with different combos just out of I don't want a huge weight up front of the 60.... and if I can get decent results here it'll be very nice....

    For those who also look at the POR board you already know this. For those who don't here goes. The two new joints are the Spicer 5-760x and the CTM. The Spicer 5-760 is a replacement joint for the 5-297x. It is said to be about 20% stronger and runs $20-$25 depending where you get it from. The CTM are $150 ea. They are the big ones.
    Before someone says it (mj) there are more concerns to running a big tire on a 1/2 ton axle than the joints. But if you're not running a huge tire, and don't want to, these might be the answer. My guess is the next week link will be the hubs, others think it will be the R&amp;P. IF one of these hold up.
    There are some people on POR who are going to test Warn shafts w/ the new u-joints against stock D60 stuff.

    Very cool! Thanks for the info.

    I'm just planing on running 36" tires max, on 1/2 axles. So this is perfect for me.

    Dep were you breaking the front when you had the BFGs or did they start going after you put on the Swampers? Do you know how much of a weight difference between your old combo and the new? How about the difference in hight between the 35s &amp; 36s? You had the front locked when you had the 35s too, right? I know that is a lot of questions but I am thinking about locking the front or going with a bigger tire. TIA.

    They were both with the Swampers, but the first one was coming off a trail, basically a dirt road and driving normal, not ruts or bumps, going up a very slight hill and BAM it blew. Got no idea why. I know why the second one blew. Keith blew a joint but his Warn axle shafts lived this time. We just replaced the joint right beside me putting in a shaft on trail 9 that day.

    My 36" swampers were about 1 to 1.5 inches taller than the bfg's but my bfgs were also a little worn, I also got the 14.5" wide ones vrs the 12.5 inch wides ones so that makes a big differene on grip as well.

    If the ujoint strength was increased 30 percent with warn shafts I think I would be just fine.

    All indications from Dana(Spicer) is the new joint, is not any stronger than the 297X .
    Warn has some test data that backs this up.
    The new joint is using the same base material, and the same process as the 297X.
    I have seem Rockwell Hardness testing on a 1995,and 2000 vitage 297X, comparied to the new one
    and there is not much difference.
    Good luck
    P.s. buy up all the 297X's you can I have a felling !

    How would you know? You have a 12 bolt front axle, don't you?

    Isn't it the super strong, no possible way to turn, semi floating design front axle?

    I still say the key is forging. Forged joints would have to be stronger.
