s/flip with zero rates-pinion angle??

[southernspeed]

I posted this on the ORD page but couldn't get an answer. Can anyone help me out with a shackle flip/pinion angle question?

Didn't need to on my 71 Blazer. What you need to do is do the shackle flip and if you have any problems correct them. Most people don't have to correct the pinion angle with just a shackle flip, go any higher and you probably will.

It's just that as I'm having to make some zero rates I thought I'd make some angled ones if necessary. I can't see me needing to alter it but I'd like to hear some opinions. I guess if you've got away with it, I'll be ok. Thanks.

It seems to vary by truck. Some do some don't. Do the flip and go drive it. No vibes, no problem. IMO

Ya yer at amount of lift where some do some dont. On my Blazer with about 4-5" lift I had degree shims and had to get a CV shaft to get rid of the vibes. While I know of others who were fine. Some just ran degree shims, T-case drop. The best thing would to get er all together then measure the angle and go from there.
