AVO Caster Adjustment Bushing System
The Caster Adjustment Bushing system does just that, increases the caster up front slightly, and also replaces the big, squishy tennis ball that the front suspension pivots on with a harder polyurethane bushing. The increased caster will help both turn-in and straight line stability.
