Robert's 2007 Hummer H2 now carries the same three-chime roar as a freight locomotive after installing a Nathan AirChime K3 Train Horn. Mounted along the frame rail, the reconditioned aluminum horns deliver a thunderous chord that matches the H2's size and attitude. The horns connect to a half-inch valve and supply line so the H2's onboard air system can feed them plenty of volume. A 5-gallon tank and 150 PSI compressor combo keep the K3 ready for long blasts while still supporting tire inflation and air tool use. Each K3 horn was sandblasted, powder-coated, and fitted with new stainless diaphragms before installation, giving Robert authentic railroad tone with fresh hardware. The result is a Hummer that sounds as bold as it looks every time the horn button is pressed.
