What driveshaft lengths are you guys running on your RCSB/4l80e combos? What diamater shafts are you guys running that race your trucks?

 

Length all depends on the Yoke you use at the transmission and what rear end you have. Best thing is to measure for your particular needs at ride height. I found this nifty little chart online for over all transmission lengths.

rclb running stock single shaft with strange 1650 yoke on 4L80e. Limited time on combo but you don't have to make a custom shaft to do the conversion...

 

Thanks for the replies fellas, I am just trying to get an idea of the typical length so I know what kind of critical shaft speeds I'd be looking at.

 

Same here stock shaft running long tail th400 yoke that's counter bored

 

I am also running the original stock 3" steel shaft that came on my truck with a Strange 1350 yolk and bastard joint. I measured it once and IIRC it was 54" center to center on the u-joints. I've been contemplating running an aftermarket shaft for several years now but so far the stock shaft has not given me any reason to change it.
