Paul took his 2010 GMC Sierra 1500 Crew Cab to an entirely new level with the legendary Nathan AirChime K5LA Train Horn, a horn known for delivering the exact sound you’d hear from a real locomotive barreling down the tracks. Originally designed for trains, the K5LA is one of the loudest and most iconic horns available, and it’s now commanding the road from under Paul’s truck.
This setup doesn’t just make noise, it makes a statement. Whether he’s alerting distracted drivers or simply enjoying the roar of raw power, Paul now has the unmistakable multi-chime tone of a true train horn at his fingertips. Cleanly installed and backed by a heavy-duty air system, this Sierra is all business when that horn hits.
