Driver Extreme Heavy Duty Antenna Spring

This Driver Extreme heavy duty antenna spring is crafted from stainless steel and braided copper wire for superior strength and corrosion resistance. Its 3" by 1" dimensions can handle heavy antennas, providing greater stability at highway speeds than other antenna springs, including Firestik's HD Spring. Ideal for reducing sway and keeping your antenna upright.

Every antenna should have a spring to protect the antenna, mount and vehicle. These springs are made from long-lasting, top-grade electro-polished stainless steel. The upper and lower inserts are made of chrome-plated machined brass and have standard 3/8" x 24 threads to fit all standard 3/8" antennas, mounts and accessories. The heavy-duty model may be used with antennas up to 48". Each spring is about 3" (76mm) tall with a diameter of 0.800" (20mm).
