James installed our Conductor’s Special 127H Train Horn Kit on his 2001 Chevy Silverado 2500HD, adding a loud, deep honk that can’t be ignored. He also added the Wireless Horn Activation Remote, letting him honk the horn from outside the truck — up to 100 yards away. This setup brings reliable performance and ease of use to his Silverado.

The Conductor’s Special 127H includes the Shocker XL train horns that deliver real train horn sound in a compact setup. It fits the 2500HD well and provides quick recovery, so the horns are always ready. Built with durable components, this kit is made for regular use and dependable performance on the road.

James’s Silverado 2500HD now has a horn kit that delivers loud, clear sound with wireless control. The Conductor’s Special 127H Kit is a solid choice for truck owners looking for strong sound and a clean, efficient install.
