DOM vs Cromo and thickness for driveshafts

Ok, yes I searched...

JKU, 6630lbs, PR80 rear, trailing arms-C/O and bypasses about 18" travel.
Street driven to and from trails.

1350CV and 1410 at axle.
about 30" of tubing.
40" overall.

Present shaft is 2.75OD .83 tubing, Adams made it so not sure if its std tubing or DOM.

Rock took it out and LS finished the job, twisted it until it ripped apart.

So some say .250 DOM will have issues at hyway speeds, so go .120 or .188
Some say Cromo but can't find anyone that can retube it.

Thoughts besides staying off rocks?

I was gona build mine for my 1 ton yj with 1.75 .120 DOM.

But then again I'm no one important, and I dont go on the highway.

I think for trails DOM will be fine at .120 wall. Idk about balancing and driving down the road.

You can do a 2.5" x .120 wall. Thats how I had them build mine (1350 CV, 1410 slip, 1.5" splines and 2.5 x .120 tube). I wouldnt suggest 1/4" wall for the rear of a street driven vehicle. I also have a spare shaft from an F250 that uses 2.75 x .083. I asked if they could retube it to .120 and they said they could not because of the odd size. About to order my front and Dan over at Adams said he would let me know if it would be worth it to go 1/4" over .120. Not worried about the front because it doesnt spin on the road.

Those trailing arms are badass, how do they preform on the trail?
Sorry to hi-jack, to keep the topic. I ordered WOD driveshaft kits for my one ton lj with ls and bypasses, 2.5" OD x .25" wall. I have not driven it on the street yet so cant really help there.

Works great..rocks, street and hauling ass in the desert esp once my shock tuner dialed all in.

FYI, every DS shop said .250 won't work on the street unless VERY short piece of tube. I've got about 30" of tube and .188 longest recommended.

The tube portion of my rear driveshaft is around 50 inches and is 3Ē .25 Jesse from high angle built it for me. Iíve driven probably 15,000 miles with it on the street and trail with zero issues

Maybe so, but he will tell you it's a bad idea also. Hard on bearings and seals I guess.

Im pretty sure he will do chromo.
