Steel Pinion Castor / Shims (pair)

Caster angle has alot to do with many steering issues you may have. Most just worry about their pinion angle in the front but you have to deal with your caster angle first and pinion angle second. You generally between 2 and 5 degrees positive caster. That means the top of your tire is angled toward the fire wall. Kind of like a bycicle.

For the rear you have to set your pinion angle differently for the type of drive shaft you are running. See the attached graphic.
