Okay, been hogging and grinding the hell out my CV joint, so I can get better angles. New u joints and ball and seat. New paint too. lol
In the first pic, I get 40 degrees of joint flex without binding.
Second pic I get much less, I need to remove more metal (as illustrated by my mastership of Paint)
To achieve this, I showed in the 3rd pic where I need to grind out the inner lip on the inside of the flange. Removing about an .125" of metal.
My question to those of you who have modified your stock CV joint to run at greater angles, how much flex, in degrees have you been able to successfully attain? I know that many will tell me to call Jess and have some built, but right now, its not in my budget, and I am going to make this work.
Thanks for the help.

Not a Chevy d-line but on my Toy double cardan the 'limiting" factor was pretty much the joint that interfaced between the two u-joints (not sure what that is called exactly in Toyata land). After grinding the hell out of that area I got just slightly over 40* at the point where it starts binding. Never been a problem on the trail. Oh yeah, my front d-shaft is 37" long and I'm running a HP front third and 5 inches of lift if that helps any.

usually you can get 45-50 degree of flex before the ball socket starts getting to much stress on it

An update to my thread, I finished grinding out the spots illustrated on the above pics. Phase 2 reassembly has yielded about 52* of flex.
So I am pretty happy with it, and I'm gonna run it till that stupid 1310 front joint goes bang.

I have ground those the same way before. It works prettly well!

I ground mine like that, then it pretty much just blew up.:laughing:
The CV went before the front 1310 on mine.

i measured 43* on my grind job when i noticed that the joint was starting to interfere.
