Guys I am about to under go a 4l80 swap on my rcsb sierra. I recently had 4.10s installed and my driveshaft is not happy about it. That and the 4l80 swap has me in the market for a new one. What are yall using for driveshafts with 4l80.

 

I had mine shortened and high speed balanced plus new u joint. Only cost about 140 iirc.

 

heres the truck


had that done to the stock piece? well hey i might end up doing that

 

Yeah. I used fort worth gear and axle. I'm sure there is a place near BR that could do it reasonably priced, or you could order a custom one from Dennys driveshaft or somewhere like that for more $$$.
