These guys made me a 3.5" steel one piece.It is one of their performer series.

 

who told you 200mph? Drive shaft balance machines go off rpm, and most only go to 3500rpm.

 

Yeah man I edited my post because it is not in writing on their web site.I thought when I ordered it the builder said 200 mph but I could be wrong.It just stuck in my head because I thought it sounded odd also.

 

Just called em, seems a 4" 1/8" wall aluminum shaft with all 1350s will run me about $500.

They dont think the length will be a problem

 

I thought I read somewhere the angle at the front of the driveshaft and the chunk were supposed to be close to opposite of each other.


Found this I didn't read all of it maybe it will help.

this is what was left of mine after a 130+mph run

 

yikes, thats pretty nasty

I just off the phone with texas driveshaft specialist for a 4" 1/8th wall single piece driveshaft with all 1350s, im pretty physced.

I made my old one work for now, but there is a pretty wicked vibration, so its a good thing I dont have to drive fast.

 

im gunna have to get another one sometime... i just dont wanna spend like 500 for a shaft

 

you can have my old one for $100

 

min only vibrates a tad when at wot from 70-80 then smooths back out
