Lucas’s 2008 Chevrolet Silverado 2500HD features Shocker XL Train Horns for authentic four‑chime train horn sound. The horns‑only setup gives you flexibility to pair with the air system that fits your needs and budget.
As a horns‑only product, the Shocker XL includes the four‑bell horn, 1/2" stainless electric air valve, hoses and fittings, and mounting hardware. Pairing these impressive horns with our HornAir 232 onboard air system provides Lucas with a versatile and extremely loud train horn kit. The onboard air system is not just for honking; it's also capable of airing up tires and powering small air tools. This dual functionality makes Lucas's Chevrolet Silverado 2500HD a true powerhouse, both on and off the road.
Built from fiberglass‑reinforced ABS and rated up to 150 PSI, the Shocker XL is tough enough for daily use. Plan your mounting and routing to clear exhaust, suspension, and driveline components on the 2008 2500HD platform.
