    I had made up a couple sqare tube spare driveshafts and after sending my $400 front shaft into little pieces this weekend I got to try the square one, let me just say that they are VERY strong, I got up on a couple rocks with it and it diddent even dent /forums/images/graemlins/grin.gif and for $15 for ends at the junk yard it's well worth it /forums/images/graemlins/laugh.gif

    yup, square fronts are great for crawling.

    I am contemplating making a square rear for trail use only. Get to the trail, drop the "driving" drive line and bolting up the "trail" (square) driveline. /forums/images/graemlins/thinking.gif

    is there any reason why you couldnt use a square driveshaft all the time? would it vibrate to much? /forums/images/graemlins/thinking.gif

    seems to me that a square tube would not handle minor encounters with rocks or stumps as well as round tube,for the same reason that tires arent square.i can remember being hung up with my front shaft on a rock with all 4 wheels spining.i would be willing to bet if i had a square driveshaft something would have broke,either the shaft,or a u-joint,maybe more.also,pipe is said to be the strongest form of steel,because it spreads a load evenly.i guess thats why racecars have only round tube for roll cages.as far as it being cheap,if you could build one out os square stock,you could build one out of tube just as well.

    The square tube used for the shaft is hitch and reciever tube.

    You will break something else looong before this square tube even thinks about bending or breaking. /forums/images/graemlins/grin.gif

    no, a square tube can flat out handle more.

    I have *personally* seen a rig hung up on its rear drive line and moved" the rig over so that it can find traction.

    guy wheeled the rest of the day on it and it was fine. Show me a round driveline that can do that.

    I have also seen these work, after seeing them support the weight of a rig at the Kremmling rock crawling comp. that sold me on them.

    Zakk,
    i would argue that with you all day long.if the same type of metal of the same diameter and thickness if used,round stock is far stronger.thats just a fact.not to say a square driveshaft wont work,but they are inferior.to me its simple to understand how a square spinning object, with 4 flat sides,would have a harder time dealing with rocks than a round one.i dont know.maybe i'm tarted'. /forums/images/graemlins/frown.gif

    so explain to me what happens when a round tube is dimpled and rotational force is applied to it...

    the same is not true of square tubing.

    ok,ill give you that one.it does seem like the square stock would be less likely to ding,but more likely to cause breakage if the impact is solid.

    break a pice of 1/4" square reinforced with 1/4" reciver stock inside of it?

    If your breaking that, its the least of your problems!

    If the square is so great, I'm just wondering why High Angle or any other driveline shop doesn't start offering shafts with it? hmmmmmm

    I'd say for an emergency only use, they will work. But even out on the trail having an unbalanced shaft spinning all day will help to kill your pinion bearings on both the tcase and axle.


    Personally if I want a beefy shaft for trail use I'd just run .240 wall Chromoly or equiv, but I'm sure Jess @ High Angle could chime in and explain why such is good or bad.

    because it doesn't balance /forums/images/graemlins/rolleyes.gif

    how many Atlas 5.1's have sold? 18. you know why? the masses can't use them.

    same with Square drive lines. 99% of the population is out of the running before the first bead is welded.

    this is quicky becoming a conundrum of epic proportions /forums/images/graemlins/rolleyes.gif
