Justin’s 2017 Chevrolet Silverado 2500HD now boasts the unmistakable blast of a locomotive thanks to the Shocker XL Train Horns. Taking advantage of the space freed up after removing the spare tire for aftermarket wheels, the horns are cleanly mounted against the cross members, giving the installation a tidy, OEM-like appearance.
First introduced in 2002, the Shocker XL has become one of HornBlasters’ most iconic horns—known for its authentic train horn tone and massive volume. Powered by an onboard air system, this setup transforms the Silverado’s stock horn from a meek chirp into a deep, resonant bellow that can be heard for miles.
This installation doesn’t just turn heads—it announces Justin’s arrival with authority.
