IMPROVED LOGO ORIENTATION - Based on feedback from our TuffLock Chevy Chevy & GMC Bullet antennas, one painpoint was that when screwed-on, the antenna logo was facing an undesirable direction. We fixed this by designing the SmartLock antenna to be 360 degrees adjustable in 45 degree increments, so you can set the logo exactly where you want it. The Antenna will "click" into place giving you a firm & high-quality feeling.
IMPROVED INSTALLATION & REMOVAL - 1. Unscrew original antenna. 2. Thread on the 1-pc adapter and snug with the Allen key (included). 3. Slide Antenna over the adapter. 4. Snug the set-screw in place with the Allen key (included). That is all! The antenna comes with a newly designed 1-pc adapter that has both M7 & M6 threads so that it is compatible will all model years of fullisize Chevy & GMC pickup trucks. This includes Chevy Silverados, GMC Sierra, 1500, 2500HD, etc
FITMENT - This 50 cal bullet antenna fits all model years of full-size GMC & Chevy Trucks, making it perfect for chevrolet silverado accessories. This truck antenna
DOES NOT FIT: roof-mounted applications such as the mid-size trucks, Chevy Colorado, GMC Canyon, Avalanche, Hummer.
