This is a new high quality aftermarket stainless steel Power Antenna Mast that cost less than 50% of the dealer factory retail price. If your power antenna mast is (Stuck, Bent, Missing) and you can hear your power antenna motor (running, clicking, grinding) every time you turn on and off your radio, but your mast does not go UP & DOWN anymore, then all you need to do is replace your Power Antenna Mast. If you do not hear your power antenna motor running, then you will need to replace the whole unit. Installation is very simple and can be done without removing the power antenna motor from your vehicle. Detailed step-by-step Installation Instructions are included and written in simple english and include diagrams, photographs, & troubleshooting. We make it easy for you to install it yourself.
