Default driveshaft keeps breaking

i put a adjsutable torque arm and relocation with a safty loop and i set the rear end at -2 and for some reason my driveshaft keeps breaking from the u-joints at about 110 every time. any ideas what it might be?

make sure the shaft is balanced and the joints are fitting snug. -2* is pretty normal. you can always upgrade to a steel shaft.

I purchased a Chromoly drive shaft when I got my new rear, that might be the way to go for you. What type of driving are you doing when the drive shaft fails?

Does the tailshaft have too much clearance causing slop in the yoke?

Never had that problem and have had my car up to 160+.I've riped mine in half tho.

Have you checked the yokes rather than the U's? If you have a warped trans yoke that would put alot of stress on the u's.
