Give your full-size Chevy or GMC truck a cleaner look with antennas for hood-mounted antennas on the Chevy Silverado 1500, 2500 and 3500 and the GMC Sierra and Denali. Many TuffLock flexible models also fit 2014+ Chevy and GMC SUVs, such as the Yukon.
SmartLock™ vs TuffLock® Antennas
SmartLock™ is our premium patented (US Patent 12237563) anti-theft line: an adapter threads onto your vehicle and a set screw holds the antenna in place. TuffLock® is our original design, built from 6061 billet aluminum (bullet and 4" solid) or carwash-safe flexible material.
Choose a 50 cal bullet, a 5" short flexible antenna, or an 8" or 12" flexible antenna. The 8" gives medium AM/FM reception and the 12" gives the best AM/FM reception. TuffLock flexible antennas include both M6 and M7 adapters.
Fitment Notes
These antennas do not fit the GMC Canyon or Chevy Colorado.
