    How much stronger are they then the 1350? I know there caps are the same size but the 1410 cross width is bigger. Doesn't seem to be that big of a differance. /forums/images/graemlins/truck.gif.....1-ton or go home...

    i think they have a better opperating angle than the 1350 but i'm probbably half wrong /forums/images/graemlins/rotfl.gif

    I would say the 1350 would be stronger because when you move the caps outboard more, you put more stress on the cross shaft.

    But I do agree the 1410 would be better for those with lifts in order to get a better operating angle for the driveshafts.

    so a 1310 or a 1330 would be the strongest of them all?

    No, not stronger than the 1350 because the caps are larger in diameter than the 1310 or 1330. /forums/images/graemlins/wink.gif

    If you were comparing the 1310 and 1330 to each other, then yes, the 1310 would be the stronger one.

    But when you go to larger diameter caps, there is more material and that adds extra strength there. Just when you take the caps out further, like the 1410, the cross shaft gets weaker. /forums/images/graemlins/wink.gif

    The 1410 is stronger by a fair ammount. All u-joints end up having the same forces (moments) acting on the cross (it is the driveshaft torque). When you make the cross larger and keep the caps the same size the caps end up having less force on them which puts less load on the needles and makes them last longer. It also puts less stress on the cross where the cross necks down to be able to fit the neddles (which is where the weak point is on most u-joints).

    Does that explain it clearly?

    I think the main reason for going to 1410 is so you can get rid of the strap type of pinion yoke in favor of a u-bolt style. The u-bolts are alot stronger then the straps. Other then that I don't think you will brake a 1350 (and that is what I stuck with for my 1-ton CV d-shaft)

    The way I've read and heard it is the wider the cross, the better it will operate for steeper angles from lifts.

    But when the cross shafts get further away from the center, it puts more stress on them. This is why the 1350 would be stronger.

    I disagree. It really seems simple to me-- more material equals stronger u-joint. I agree with the 1410 having more clearance at sharper driveshaft angles. I have one at the diff. end of my front driveshaft and it has more clearance than a 1350 at the diff. Also, the factory Spicer yokes (1350 and 1410) both use the strap style attachment from the factory. Jesse at High Angle Driveline drills out the yoke to accept the u-bolt style attachment. So, the main reason for going to 1410 is to have more clearance at steep drivline angles, but I still think the 1410 is stronger than a 1350.

    Ok, I give up. /forums/images/graemlins/tongue.gif Everybody is entitled to their own opinions, so, I guess the only way to find out for sure which is stronger is to wait and hear stories from those who have busted the 1350 or 1410 joints. /forums/images/graemlins/tongue.gif

    I busted a 1350 at the rear of my rear end driveline. The cross did not break, that caps and drive line ear exploded. One of the straps held one cap in the yoke and the other strap was waisted, let me know if you can see this pic...

    So now I have a 1410 coming in the mail I'll try to break that one too and get back to you all /forums/images/graemlins/thumb.gif /forums/images/graemlins/pimp1.gif
