driveline angle in a cj5?

i want to put a 4.5" rubicon express lift on my new 80' cj5 and a 1" body lift, but am curious if i have to do any driveshaft or t-case upgrades? any input would be greatly appreciated! thanks

I am sure you will have to adjust your U joint angles. I have only a one-inch lift on mine right now and have 18 degrees at the pinion and experience vibrations at certain speeds. I have a Skyjacker 2.5" kit waiting to be installed and I bought a set of 2.5 degree wedges to lessen the pinon angle. I imagine I will have to lower the transfer case also. I'm running 4.10 gears. Mine is an 80 CJ-5 too.

I run the RE 4" YJ Standard lift on my 80 CJ5. I rotated the pinion up and used a 1" drop on the transfer case. No vibes. I would feel better using a CV shaft though.

No SYE for the D 300. 80 D300's have a short output shaft. So that's as good as it gets. 81 and later D300 have a longer shaft, FYI. Yeah, sounds like you have a CV shaft in your future.

There is no slip yoke to be eliminated on a 300 case.
