just wondering what some of you guys arwe running for rear driveshaft upgrades? I broke mine today and basically destroyed it, i broke the front and back u joint and the slip yoke ripped the ears off the front a back of the shaft and also stripped and broke the splines on the yoke that goes into the transfer case? anyone ever destroyed one. the trck is making about 750hp. thanks danny
 
I'm running a 1-piece driveshaft. Got mine from Doghouse Diesel. It really made a ton of difference over the stock driveshaft. ALL the speed related vibrations are gone. Shutter is gone, Best mod I've done.

you shouldn't be breaking driveshafts at 750hp, but I just had a whole new driveshaft made and it was made out of steel, but the guy said it was stronger then stock and its a 4" tube now. it was only about 360 in change.
 
ive seen 400hp trucks break driveshafts, what are you talking about? Im simply asking if anyone has upgraded theres, im not saying its becasue i have 750hp Im stating it becasuse maybe someone has had one built to withstand alot of power...
 
I am going to have a local driveshaft shop make a rear aluminum shaft.....with 5" diameter AL

Some info on shaft diameter:

5" would need 7400 rpm and 11,000 ft lbs to break

6" would need 8000 rpm and 14,000 ft lbs to break

Of course, this is just for the shaft

The ujoints and yokes might be the weaker factor.....

Call Bowersock, and ask him where he had his driveshaft made. It was local, and I am pretty sure it's the same place that built Brandon Miller's driveshaft for his s-10 drag truck.

Just stick to 1/4 mile stretches of pavement, and ditch the truxus :poke:

You know you shouldn't be breaking stuff when a VP truck takes you down at a dyno day :hehe:
 
Blah blah blah...I have other things, aside from weight and HP, working against me.

Fibber or not, I was the one that left the dyno with a complimentary can of Tire Shine!
 
so do I called 35 trxus and 20x10 wheels we could play this game all day long, you and 12v redneck should be brothers..haha jkjk. we will decide this one day, i will be on 31's and spraying, then i know another black truck that will jump in on the action..
