Pinion angle

Just got ths new transmision in and am working on getting the correct angles. What's everyone run? I'm seeing mixed answers. Finding alot of info on ladder bar and 4 link stuff. But very minimal info on leaf cars. This is a caltrac car if that matters.



Currently the trans is 0* and pinion is 4* down.

4* down is good for leaf spring. General range is 4-7. 4 link and ladder bar are 3*.

How much angle you run depends on how much axle wrap you will have. Leaf spring cars obviously have more than 4 link cars, etc. That being said, I run a Caltrac system ( including their single leafs ) and you can run enough preload to just about eliminate axle wrap. Mounted my camera under the car on a few runs to prove this. I usually run zero preload and at that setting there is some wrap. I usually run 3 down at that setting. Still a guess - I guess. Aint had the driveshaft roll out from under the car yet Some times 4 or more down will give you some interesting vibs on heavy decell.

If you run an auto try 4* down. That is what I run in my Aspen and it works great with Cal Tracs. If you have a manual tranny you will need 6* down. That worked well on my 74 Duster 360.

That's about where I'm at, 0 trans 4-4 1/2 down on pinion many years street/strip.............
