Heavy Duty Zinc Plated Barrel Spring Base for Powered Whips (.283 Zinc Plated for corrosion resistance). With RCA connection at bottom.

SafetyWhips® Spring mounts are highly recommended to help reduce whip breakage and wear and tear on whip. The spring provides a higher threshold for jarring and jolting as it reduces the amount of pressure placed on the whip pole when jolted driving your vehicle over rocky rough terrain or heavy equipment jolts from use of heavy equipment.
