Tech Insight

Delrin is RockJocks material of choice for AntiRock bushings because it eliminates squeaks without the need for grease fittings while maintaining tight bar control. Because the spline interface is standardized, bar stiffness changes are achieved by swapping torsion barsnot bushings, and this bushing will support all 25-spline bars regardless of center diameter.
