This can be done with wedges between the axle and the springs. | | | | | Joined: May 2005 Posts: 8,878 . | | . Joined: May 2005 Posts: 8,878 | king pin inclination angle is measured 90 degrees from the caster angle.
It is how much the king pins lean in from vertical.
Don't have an answer, but sometimes the left and right side angles will vary a part of a degree to account for the curved surface of the road and which side you usually drive on.

The dimension between the two is the Included angle. SIA is non-adjustable. If it is out of spec, that indicates a bent spindle. They should be the same on each side, withing no more than .5 degree difference.
