Vehicle 2021 RAM 2500 limited

Adam took his 2021 RAM 2500 Limited to the next level with our Shocker S6 544K Train Horn Kit mounted on the robust Goliath Bracket. This powerful setup delivers a deep, aggressive blast from six Shocker horns, all securely mounted in the spare tire location for a clean and stealthy look.

The system includes a 5-gallon air tank and our 1NM air compressor, both mounted alongside the horns underneath the bed. This keeps the truck bed free while giving Adam fast air system recovery, 10–12 seconds of honk time, and full onboard air capabilities for tire inflation or light air tool use. With the Goliath Mount, this install is solid, efficient, and built to perform.

Key Features:

Shocker S6 horns for a massive, real train horn sound
Heavy-duty 544K air system with fast recharge and extended honk time
Onboard air functionality for inflating tires or running small pneumatic tools
Goliath Mount secures all components in place of the spare tire
Clean and space-saving install with no sacrifice of bed or cab space
