360 Magnum with 42rh install angle question.

Truckie said

I believe I have read that the factory recommends 2-4 degrees down at the tail shaft. So if I set the tail shaft at 3 degrees down, does it make sense for the pinion angle to be 0 degrees? That way when it’s under power the rearend can wrap up to about 3 degrees pinion angle?

In theory ^^^^

3° down at trans tail shaft
3° up at rear pinion angle

When under power is good, allow a degree or 2 for rear end wrap up when under power.

So the more power and the harder you drive figures into your wrap up degree guess.

Want the angles equal when under power.
