What's the length limit on a 1 piece driveshaft before a 2 piece unit is needed?
68-70" or so. but maybe jesse or another expert might have a different opinion....
its 6 or 8' before a steady bearing and 2 pieces is needed. I just don't recall if its 6 or 8. I think 6'.
The longest one I've ever put together at HAD was about 5'. After that they become a pain in the ass to balance. I don't think Jesse will do a 1 piece over 6'.
Cool, thanks guys.
the 1 i have is 64" long no probs yet
Well, it depends partly on how fast you intend to spin and the mass of the shaft, as well as the length. Crown Vic cop cars have some mighty long driveshafts for a car that can have a 3.55 rear end and a top speed of about 150mph. Because of this, they use a lighter shaft (than those used in the non-P71 cars) so the shaft won't try and shake itself to bits at top speed.
How long is my shaft??
Longest one peice driveshaft I have owned /seen so far,is the one in my 81 G10 Van with a 125" Wheelbase..its either 69 or 70-1/2" long,I forget which..only reason I know is I had a hell of a time finding one that a forkloader hadn't squashed already at several junkyards, when my i discovered my original one had a big dent in it,and it vibrated some at 65-70 mph..
I'd think any longer than that, and it would bow in the middle under torque!..
