DEREK'S 2008 GMC SIERRA 2500HD

This is Derek's 2008 GMC Sierra 2500HD that features a Nathan Airchime K3 train horn and a Shocker XL train horn. With the combination of our loudest horn that we manufacture and an authentic locomotive horn, Derek can be heard from miles away! Powering these horns is our HornAir 540 onboard air system that includes a 5-gallon air tank and a Viair fast fill 400C air compressor.
