Kody D. gave this 2020 RAM 1500 a serious sound upgrade with the HornBlasters Shocker XL Train Horn, bringing unmistakable train horn performance to his truck. The Shocker XL is HornBlasters’ top-selling locomotive-style horn—one horn with four bells, hand-tuned to the US train horn chord—and it is built to deliver an incredibly loud, authentic blast whether you are on the road, at a meet, or off-road.

Installed on his 2020 RAM 1500, this setup gives the truck an aggressive presence that matches its bold styling. The Shocker XL Train Horn is a stand-alone horn (part AH-S4 in stealth black, AH-S4W in white): you get the four-bell assembly plus a 1/2″ stainless steel electric valve, air line, fittings, and hardware, but you still need a compatible onboard air system to complete the install. HornBlasters rates it to 150 PSI, builds it in the US with fiberglass-reinforced ABS, stainless steel internals, and brass fittings, and backs the horn with a lifetime manufacturer’s defect warranty.

If you are looking for one of the loudest train horn upgrades available for a RAM, the Shocker XL continues to be a top choice for enthusiasts who want maximum volume and legendary HornBlasters performance. Want tank, compressor, and wiring in one box? Pair the same Shocker XL tone with a Conductor’s Special Train Horn Kit—the Shocker XL is the horn featured across that lineup.

Frequently Asked Questions

It is a stand-alone horn. The Shocker XL Train Horn listing includes the four-bell horn, a 1/2″ stainless steel electric valve, air line, fittings, mounting hardware, and instructions—but HornBlasters is clear that you still need an air system (tank and compressor) to honk. Kody D.’s 2020 RAM 1500 uses that horn-first path. If you want everything in one box, shop a Conductor’s Special Train Horn Kit.

One horn with four bells. HornBlasters markets it as the Shocker XL (also listed as Shocker S4 / AH-S4). The four bells are hand-tuned together as a single US train horn chord—not four separate horns. That compact four-bell layout is a big reason it fits trucks like Kody’s RAM 1500 without a full locomotive stack.

The horn is rated to a max working pressure of 150 PSI with a 1/8″ M NPT air inlet on the horn itself; the included valve is 1/2″. Size the tank and compressor to the honk time and recovery you want. HornBlasters’ ready-made path is the Conductor’s Special Train Horn Kit lineup, which already pairs this same Shocker XL with 127H through 844K air packages. Always re-read the live spec tables before ordering.

HornBlasters calls the Shocker XL the loudest horn they make and notes it is hand-tuned to US train horn chords with about a 1.7 dB difference from the real thing. Third-party side-by-side tests on the Shocker XL Train Horn product page are the best place to hear how it stacks up against typical air horns at the same pressure.

HornBlasters backs the horn itself with a lifetime manufacturer’s defect warranty. Other included components (valve, fittings, and similar hardware) carry a 2-year manufacturer’s defect warranty. Confirm the current terms on the Shocker XL Train Horn product page before you order.
