Title: Correct pinion angle for a flipped rear?
Post by: 82ChebySWB on May 02, 2010, 09:34:40 am

Good morning, Does anyone know what the correct pinion angle needs to be for an '82 SWB with a flipped rear?  I've got a custom 4" built all aluminum drive shaft that I'll be running...and I want top make sure that nothing is in a bind at all.

THANKS,

Brian

Did you use a kit to flip it? If so which one? Here's a few articles

Yes, the rear was flipped using two "off brand" Ebay Special U shaped brackets.

The motor will be solid mounted....and a Poly trans mount (since the first link you posted suggested that mounting points made a difference in rearend movement)

you want to be about 3 or 4 degrees.
