Dorman Antenna Mast For Chevy Silverado 1500 – 37.7 Inch, 7mm Base Thread (M7x1.0), 76003

Is the antenna on your Chevy Silverado snapped off or bent?

This Dorman mast, part 76003, is the replacement.

It's 37.7 inches tall and has a 7mm threaded base (M7x1.0).

But here's the thing—GM used two different thread sizes on these trucks.

You gotta measure yours to make sure it's the 7mm before buying.

It replaces the OEM number 22876544.

It's a new old stock style mast, just screw it in and get your radio reception back.
