pinion angle

Pinion angle needs to be set so the rear u joint runs as straight as possible on acceleration ---Trevor

On our 71 Nova we set the pinion down about 4*- 6* which ends up to be 0 under heavy acceleration with spring deflection. Maybe old school but will find out from others.

There is a very good article on the Internet google pinion angle can't remember the site
Wolferacecars.com I think

That's what I've always heard, too. I'd like to know how "they" know when it's zero under acceleration.

best possible set up is u joint is zero at pinion and the angle is at the trans, under acceration to avoid any drivelin vibration ,if you car sits high the pinion angles will be optimum but if running stockers you might have the pinion angle going negitive because of ride height but will have the correct drive shaft angle ,,just my 2 cents from my application gmonde

On our mopars the Calvert system does not generate nearly the rear end travel
of the old SS Springs. We run 1 to 2 Degrees on both ends of the driveline.
When we set them at 6 Degrees like the SS Springs we had a noticeable vibration
according to Jon Jr.
The Calvert system (Springs/Bars/Shocks) is some of the best money we
have ever spent on our stuff. We run a dozen cars with them including our
Super Stock/Super Street cars running on Transbrakes.
Calvert always seem to have time to help you no matter how busy
he is and is one of the Fairest and most Honest Manufactures we have meet!
