Okay need a driveshaft soon what kind of should I get Aluminium or steel for +1000 rwhp twin turbo nnbs truck am building.

I just want something that could hold up and handle some abuse, I know that steel is right choice but wondering about rotating mass and performance effect.Link off the truck is below

What do you guys think ?

 

I have an aluminum one from the Driveshaft Specialist. I don't know what it will hold up to power wise but diesel trucks run an aluminum driveshaft too so I'm hoping mine will be fine.

 

Thanks scooter I'll give them a call on Monday and ask, they might have a better idea.

 

Go with a 5in al

 

Well, I just talked to them and asked them about 5in al driveshaft torque rating.

They said they had a diesel truck that weights 8000lb pushing 1000 whp & 2200tq with 5in al.

 

Did they mention what ujoints that was with? Probably 1450 or larger.
