I would rather have the skinnier one, for a little more ground clearence. I wouldn't think it would be that much weaker. I dunno for sure. I've already destroyed 2 of the thicker V6 shafts(big rocks). I need something much stronger than both.

 

Cool beans, maybe someone needs to bring out a titanium driveshaft.

 

titanium wouldn't be a good driveshaft material. especially for rock crawling. it's tortionally brittle and score marks would kill it early.

my '97's driveshaft is aluminum. checked it out today...i'm thinking about polishing it for ▓▓▓▓s & giggles

 

Well alright, so I guess that wouldn't work. Didn't really think it through when I posted.
