Mark M. upgraded his 2026 Chevrolet Silverado 2500 HD Z71 with our HornBlasters Stealth Spare Tire Delete Kit, creating the perfect mounting solution for his train horn setup while keeping everything tucked away cleanly underneath the truck. The variant on that listing is 2-Gallon Tank / Stealth Black (HK-STEALTH)—HornBlasters’ lower-profile spare-well package with Shocker XL bells, a 2-gallon six-port tank, and the 3Q compressor.

Installed in the spare tire location, the HornBlasters Stealth Spare Tire Delete Kit provides a secure and discreet mounting platform for train horn components without sacrificing valuable bed space. The factory-style fitment makes it an excellent choice for Silverado owners looking for a clean and professional installation. HornBlasters engineered Stealth for more full-size trucks and SUVs than earlier STD layouts, with bells tucked into the well and extra ground clearance versus the previous spare-delete stack.

This 2026 Chevrolet Silverado 2500 HD Z71 is a great example of how the Stealth kit can simplify a train horn installation while maintaining a sleek appearance. By utilizing the spare tire area, Mark was able to maximize available space and create a setup that looks as good as it performs. HornBlasters lists 150 PSI operation with 110 PSI restart, roughly 20–22 amps max draw, and published fill rates of about 3 min 59 sec from 0–150 PSI and 1 min 33 sec from 110–150 PSI on the 2-gallon Stealth page.

If you’re looking for an easy way to mount your train horn system on a Silverado HD truck, the HornBlasters Stealth Spare Tire Delete Kit is one of the cleanest solutions available. Need longer honks? Step up to the 5-gallon Stealth option (HK-STEALTH-5) on the same configurator, or compare layouts on Stealth Spare Tire Delete kits and Spare Tire Delete kits.

Frequently Asked Questions

The product URL for this install points to 2-Gallon Tank / Stealth Black on the Stealth Spare Tire Delete Kit configurator—part HK-STEALTH. That package includes Shocker XL horns, the Stealth spare-tire-delete bracket, a 2-gallon six-port tank, and the 3Q compressor. If you want a longer honk window, choose 5-Gallon Tank (HK-STEALTH-5) on the same page.

Mark’s truck is a 2026 Silverado 2500 HD Z71, but spare well dimensions and underbody routing still vary by cab, bed length, axle, and options. HornBlasters says Stealth fits most full-size pickups and SUVs. Use fitment notes on the Stealth Spare Tire Delete Kit listing plus resources linked from Spare Tire Delete bracket selection when applicable. If you’re unsure, contact HornBlasters support with your build details before you order.

Yes. The Stealth Spare Tire Delete Kit occupies the spare location with horns, tank, compressor, and supporting hardware instead of a full-size spare. Many HD Silverado owners carry a compact spare elsewhere, rely on roadside assistance, or pack a tire repair kit—pick the backup plan that matches how you use your truck. Mark’s build prioritizes bed space and a hidden underbody install in that same well.

HornBlasters lists 150 PSI operating pressure, 110 PSI restart, a 2-gallon six-port tank, the 3Q compressor, and up to roughly 20–22 amps max draw for HK-STEALTH on the Stealth Spare Tire Delete Kit product page. Published fill rates are about 3 min 59 sec from 0–150 PSI and 1 min 33 sec from 110–150 PSI. Always re-read the live spec tables before ordering because HornBlasters occasionally updates components.

Both occupy the spare tire well with HornBlasters train horn performance and onboard air. Stealth focuses on a slimmer, more discreet stack—ideal when you want maximum sound with minimal visual bulk under an HD truck, exactly what Mark M. achieved on his 2026 Silverado 2500 HD Z71. HornBlasters also notes Stealth is not compatible with S6 mounting extensions; extra bells must be mounted individually.
