Ss springs and pinion angle

[mikesduster]

I put a set of SS springs in my 72 duster a few months ago but I havent set the pinion angle yet. Ive asked a few people and of course,I get numerous answers so I thought Id ask on here.

Right now its at 7 degrees and some say thats fine but some say 2-4,3-5 and 5-7. What say you???

MP suspension manual says 5-7 degrees.

Would it make a BIG difference if it was 5 or 7??

set it so with shims you can go to either end of the recommended angle.8)

so set it at like 5* nose down, they make 2-4* shims 'lakewood'

The problem with pinion angle is it changes under load (at launch, when it's most critical) depending on your power level and suspension setup - either a little or alot. A stout enough rear, 4-link or mayde Caltracs will give very little pinion climb, so your static pinion angle can be less. More power with less axle control means you need more pinion angle to compensate. That also translates into greater u-joint stress (shorter life) in normal driving.

I already have the shims but didnt put them in yet. I have a SB with about 500hp,727,8" 4200 converter and 4.56's. Its gonna leave pretty hard.:-D

Run it as is. You are in the range that SS springs tend to like.

This. It's IN spec so try it like it is. It'll be fine. It'll probably set your eyeballs back in your head. lol
