I have a 01 rcsb I'm doing a 80 swap on I was told u need to trim the new 80 yoke where it meets trans ...

Anyone know about how much needs to be cut?

Thanks

 

i actually didnt need to cut any off of mine never hit but i have a sligtly shorter yoke then most too

 

I think I did a long turbo 400 yoke and cut off around 5/8th of an inch.

 

I used the yoke that was with trans off the 03 1500hd . It was too long so I cut a inch 1"1/4 off

 

did it work fine? im in the process of doing an 80e swap on my regular cab 2wd I have been trying to search as many thread as i can to gather all the right information. let us know how the swap goes thanks...

 

on my truck i used the TH400 Long Yoke... trimmed 5/8" off and put it on.. done deal.

 

thats ok buddy, we are all built different


i took mine to a local shop that builds drive shafts. he put in a yoke for me along with new u joints

cant say where he got it from or if he made it, but it works!

 

i had a short th400 yoke my first go around and it vibrated very badly. Found out it was due to the splines inside the yoke were back about an inch from the end. So this made the yoke only catch right at the end of the output shaft of the trans. Swapped over to a long stock 4l80e yoke and cut an inch off. Works great. Also, check and make sure the bushin inside the tailshaft housing is still good. That will make one vibrate around also.

Just my experience. Learn the hard way some times.
