The manual discusses correcting the caster angle but I can't find where it states what the correct angle should be. My old springs had eight leaves and a short wedge shaped ninth leaf that the through bolt went through also. My new springs have eight leaves as I understand is correct. What degree shim wedge should go under the spring when I install them? Thanks | | |

You can buy caster shims/wedges at your local spring or hot rod shop or online from various vendors.More castor increases straighline stability and adding a touch more steering effort.Too little castor may cause a shimmy. Make sure the trucks king pins are in good repair. | | |
