Which one is better and will a 1pc hold up to the 450ish Hp/Tq I am making. I also run slicks at the track so not looking to wipe everything out. It will have a drive shaft loop. The one i am looking at is a 1 pc 4in aluminum.

Seriously?

2 piece is clearly stronger. 2 short pieces will maintain integrity vs a long 1 piece.
You're a Crew Cab. why would you even consider a 1 piece?
People break a 1 piece with regular cabs. You'll damn sure snap one with a crew.

yeah seriously!
That's why i asked, and my ride is a ecsb. Seems like the carrier bearing would be the weak link.

i haven't heard of anyone breaking a 2 piece driveshaft, so i think you'll be ok. the 1 piece break all the time though

Looks like CC i your sig.

As stated, i've NEVER seen a 2 piece break. I've had mine up to 134mph at 6448 rpm on 275/45/20"s and have had NO problems with the carrier.

I agree, I have had mine up to 156 on the dyno and no problem here either. I'm just asking a question and checking to see if my idea that a single piece would be stronger. But i see that you and other think that the 2 piece is the way to go. I was just looking for input.

Try a search in the drive train section for Aluminum. See if you can find some threads on aluminum driveshafts.
However I don't think many people can properly build an aluminum driveshaft long enough for an ECSB and if they do I doubt it will hold much power.

2 shorter drivelines set at correct u-joint angles are much more stable at high speeds under load than one long driveline.
