[robrocketanski]

i know i have seen this discussed before but i could not relocate the info or threads.

i will be retubing my rear shaft next week and want to know what wall thickness people have.

run as thick as you can and still get balanced. if the truck is a DD if not run .250 wall :D

Mine is the Metric equivelent of 3/8 wall DOM. I paid like $80 for 30 or so inches of Tube and built it myself.

[robrocketanski]

80?! i was thinking 10. is there a reason so much? and isn't 1/4" pretty good?

I can't remember how thick my .....is..... Its from Hi Angle, if I recall 1/4 is way too thick for a "DD" to be balanced... 3/16? mabey?

Thats alot of weight to be spinning around at highway speeds anything 1/4 and thicker

My front is square and weights a ton

[robrocketanski]

yeah, front is a whole different issue. i am thinking of making one from tractor stuff? i will play with it.

i think i will go roughly 1/4" wall, i will be lucky if this beast goes down the road at all. no way it will dd :yes:

so should i be buying sch 40 or 80 or a certain dom? i don't know metal stuff well. i will ask some mech eng majors here on campus.

I think that 40 would better than the 80 as its "thinner"

I'm sure it "won't" be an issue but I wonder if DOM would be better as the "seam" is stronger??

I bet by the time the seam would fail the muffler bearings would be shot anyways so its all moot :kidding:

I'm doing the same thing. I originally thought that .250 or .220 would be really heavy. But, I changed my mind after I did some measuring. I need 26" of tubing for my driveshaft (about a 48" driveshaft). .220" wall stuff is about 4-5 lbs heavier per foot than stock stuff, so roughly 10 lbs added to the driveshaft. Stock shaft weighs 23lbs (with CV), so it's less than 50% increase in weight. I think I'm going with .220". I drive on the road quite a bit, although my 'Yoter isn't a DD.

I change my muffler bearing at every 25 000 miles, I don't want to be stranded on the road because of that damn part!!
