Overview

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.

Shipping

Orders are processed in 1–3 business days. In stock parts ship promptly from our partner network. Special-order items either aren’t currently stocked or are built to your spec — expect 4–6 weeks. If a part goes on backorder while your order is in the queue, we’ll reach out and work through discounted alternatives together.

Free shipping over $200 in the continental US. Alaska, Hawaii, U.S. territories (Puerto Rico, U.S. Virgin Islands, Guam, American Samoa, and the Northern Mariana Islands), and international orders carry surcharges — most appear at checkout. Some exceptions (LTL freight, or suppliers who quote freight only after we place the order) won’t. In those cases we’ll reach out with the exact charge before your order moves forward.
