I found this pinion angle finder tool on Summit.
Was curious on how it worked and if it would be any good?
It's cheap, so is it worth the buy.

For the $$, you can't beat this magnetic version from Craftsman.

Your not kidding! Great find!
Still trying to figure how it works exactly. I beieve it will need to be placed on the driveshaft to get the angle. Is that right? I will be definately buying one and measuring my pinion angle prior to lowering the rear. Then after I lower it, that tool will let me know how far I'm off.
Sounds logical to me.

You need to place it on the snout of the diff to get the angle.

Edut: he beat me to it

That is such a smart and cheap tool. Everyone about to lower their truck should have this tool. Hell, for that kind of money, it should be offered as an option with lowering kits.
I still think the guys with a 2-piece driveshaft should measure the two driveshaft angles prior to lowering. It will let you know how much has changed, and if the carrier bearing relocator bracket will help the driveshaft angle coming into the pinion and the tranny. IMO
I believe Ground Force or Belltech offers a tranny spacer to center the tranny up with a carrier bearing relocation bracket. It keeps all the driveshaft halves more in line with each other.

This is what I use

But I like to be really accurate. Comes from my NASCAR days

Here is a brief discussion on setting pinion angles from Baseline Suspensions .

I found it helpful when I did mine.

I like the diagrams showing how to measure pinion angles. Though the problem is, what is the correct pinion angle that you need???
That answer would be gold. What measurements are needed and how do you get the proper measurement. Basically, what is being subtracted or added to what between the pinion angle measurement and the driveshaft measurement?
This where the algebra comes in life! I was wondering what I would ever use it on.
