4-Chime Air Horn Kit

Angel C. recently completed the installation of the HornBlasters 4-Chime 3-Liter Air Horn Kit on his 2007 Dodge RAM, giving the truck a bold, attention-grabbing presence on and off the road. The kit was installed with a clean, well-planned setup, making it a solid fit for both daily driving and show use—far louder than the factory horn without stepping up to a full multi-gallon train horn package.

The 4-Chime 3-Liter Air Horn Kit is a complete HornBlasters package: Rage 4-chime air horns with a pre-installed 1/4″ electric valve, a pre-plumbed and pre-wired 3-liter compressor and tank combo, pressure switch, gauge, wiring, fittings, and hardware. The system runs at 120 PSI with 90 PSI restart—part HK-4CHIME-M3 on the Non-Weather Resistant listing—and makes its own air on demand.

The result is a powerful, deep, multi-chime blast that transforms the RAM’s presence instantly, staying true to the rugged character of the platform while adding a whole new level of sound. Need longer honks or a weather-sealed compressor? Choose the Weather Resistant tier (HK-4CHIME-127H) on the same product page for the 1.5-gallon 127H air source and roughly 6–7 seconds of honk time versus about 4–5 seconds on the compact 3-liter kit.
