Cade W. took his 2012 GMC Sierra 2500HD from bold to unmistakable with our Conductor’s Special 244 Spare Tire Delete® Kit. This all-in-one system is built to deliver serious sound performance while simplifying the installation process, no cutting, no guesswork, just a clean, powerful upgrade that gets loud fast.
Cade's setup features the legendary Shocker XL train horns, delivering true locomotive power and unmistakable tone. The Spare Tire Delete bracket makes for an incredibly clean install under the truck bed, turning unused space into a high-performance horn mount. Paired with our compact HornAir 2HB onboard air system, Cade’s install provides up to 3–5 seconds of honk time and recovers in just 65 seconds, making it ready to fire again at a moment’s notice.
This install proves that getting LOUD doesn’t mean getting complicated, and Cade nailed it from start to finish.
