If you’ve got a “Big Mama” on your vehicle (that’s trucker slang for a big antenna and, coincidentally, our nickname for Mike's girlfriend), then you know how important it is to keep it protected under any circumstance. The Heavy-Duty CB Antenna Spring will keep the base of your antenna flexible, with just enough give so the road doesn’t take. Ideal for antennas 4’ tall, the stainless spring is rust- and weather-resistant. We recommend a super heavy-duty spring for antennas over 4’ tall, a.k.a the real “Big Mamas”.

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).

Heavy Duty Spring

This is everything you could want in a heavy duty spring. It works well with the heavy duty Quick Disconnect which I highly recommend for the 5' Firestik antenna removal when going through a car wash.

Heavy duty spring

Very nice. Pretty quick shipping and easy install. I think we all should use a spring. I'm new but I already want a new antenna lol

Holds a wire to the sky.

It is less than a month since I installed the spring on a Heavy-Duty Stud with Right Angle mount so it is still working as expected. I have not hit any tree branches yet so I really do not know how well it works. Sure does look good!

Rian Hart
It’s working

I wish it was black or black chrome.
