Spare Tire Delete S6 Upgrade

The Spare Tire Delete Kit | Heavy-Duty includes Shocker XL train horns, a spare tire delete bracket, 2-gallon 6-port air tank, 1NM Stealth black air compressor, 110/150 PSI pressure switch with relay, remote mountable intake filter assembly, spare air filter elements, D.O.T. approved air lines, Black Widow 1/2\" NPT electric air valve, 200 PSI liquid-filled gauge, fittings kit with safety blow-off and drain cock, complete wiring kit with fuse holder and fuses, mounting hardware, and detailed instructions. It is a complete train horn and air system built to mount in the spare tire location.

The Shocker XL 6 Horn Upgrade Kit adds two additional Shocker XL bells to the standard four-bell configuration, increasing airflow and broadening the horn’s tone. On a Heavy-Duty Spare Tire Delete system, this S6 upgrade gives Thrill’s 2500 an even more aggressive sound profile while still working with the same air system.

With a 2-gallon tank at 150 PSI, the Heavy-Duty Spare Tire Delete setup typically provides about 3–5 seconds of continuous honk time per full tank. The compressor refills the system from 110 to 150 PSI in roughly 35 seconds, giving Thrill quick recovery between blasts for regular on-road or show use.

Yes, the Spare Tire Delete Kit | Heavy-Duty is designed for many full-size pickups and HD trucks that use an under-bed spare tire hoist. As long as your 2500 truck has compatible spare tire mounting and enough clearance for the bracket and horns, it is a strong match for an S6 Shocker XL upgrade like Thrill’s setup.

The Heavy-Duty Spare Tire Delete system runs on 12-Volt DC power with a maximum draw of about 25 amps from the compressor. The kit includes the wiring, relay, and fuses needed, but your truck’s charging system should be in good condition to handle the compressor load. HD trucks like Thrill’s 2023 Chevy High Country 2500 typically have no problem supporting this type of onboard air system.
