Blake L. upgraded his 2015 Ford Expedition Platinum with our Spare Tire Delete Kit and the Shocker XL 6 Horn Upgrade Kit for Spare Tire Delete Kits—the S6-style six-horn upgrade path for STD—transforming the rear setup into a cleaner, louder, and more aggressive configuration. If you want serious train horn presence without giving up the refined full-size SUV look, this pairing is built to deliver.
On this build, the Spare Tire Delete Kit was installed in the factory spare tire location underneath the rear cargo area. That mounting position keeps everything tucked up cleanly while maximizing usable space and maintaining a factory-style appearance from the outside in. It is a popular approach for Expedition owners who want high output without sacrificing interior room. The XL 6 upgrade kit steps the horn section up to six Shocker XL bells sized for Spare Tire Delete brackets—exactly the kind of add-on HornBlasters lists alongside the base STD system.
The upgrade brings a noticeable jump in tone and projection, delivering a deep, commanding blast that matches the bold presence of the Expedition Platinum. By using the spare tire well, the setup not only improves performance but also optimizes underbody packaging for a streamlined install.

Blake’s build shows how a full-size SUV can stay refined and still sound unmistakably aggressive—clean install, factory-style fitment, and train horn tone done right. If you’re running a 2015 Expedition and want a clean, high-output path, the Spare Tire Delete Kit with the Shocker XL 6 Horn Upgrade Kit is a proven option for both performance and practicality.
