Caster angle (1 Viewer)

[skuli magnusson]

My caster angle is negative by one degree. I’ve got new old man emu heavy duty springs and raised shackles, I think it might be around 3 inch lift. My question is, running on 33 inch tires, what would be a good caster angle ? Not sure if I should buy a 4 degree or 6 degree shims.

Caster shims installed on the front axle, angle the back side of the differential downwards. - increasing the front driveshaft angle- putting it more out of alignment. Taller springs do the same thing, compounding the problem.

Seeing that I had a 2-3-4" front lift and never installed caster shims and drove my cruiser like that for 30 years and wasn't bothered by the steering— I'd say install the thinner 4 degree shims.

I think stock is +1 deg caster.
