Skyler W. recently installed our Spare Tire Delete Kit on his 2015 Ford F250 Lariat, giving his truck a cleaner, more aggressive look while freeing up extra under-bed space. The kit was installed in the rear spare tire area, removing the bulky stock setup and streamlining the truck's frame for a sleek profile.

The Spare Tire Delete Kit mounts a complete train horn system in the factory spare tire location, keeping the setup hidden while freeing up bed and frame space. The kit includes Shocker XL train horns on a dedicated spare tire delete bracket, paired with a 2-gallon 150 PSI air system that delivers serious sound in a clean, organized package.

The system operates at 150 PSI with automatic restart at 110 PSI, delivering 3–5 seconds of honk time from the 2-gallon tank and a fast refill from 110 to 150 PSI in around 35 seconds. The Spare Tire Delete Kit not only enhances the appearance but also makes maintenance and access to the under-bed area much easier, perfect for off-road adventures or hauling gear. Skyler's install was smooth and professional, showing how this kit can transform the rear of any F250 Lariat.

Big congratulations to Skyler W. for taking his 2015 Ford F250 Lariat to the next level. His build combines train horn performance with a cleaner, more aggressive look, proving that the Spare Tire Delete Kit can transform the rear of any Super Duty while freeing up valuable space and streamlining the frame for a sleek profile.

Frequently Asked Questions

The Spare Tire Delete Kit includes Shocker XL train horns, 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.

With a 2-gallon tank at 150 PSI, the Spare Tire Delete kit typically delivers 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 Skyler quick recovery between blasts for regular on-road or show use on his F250 Lariat.

Yes, the Spare Tire Delete Kit is designed for many full-size pickups that use an under-bed spare tire hoist. As long as your 2015 Ford F250 Lariat uses a compatible spare tire mount and has enough clearance for the bracket and horns, it is a strong match for this type of install. The kit removes the bulky stock setup and streamlines the truck's frame for a sleek profile.

The Spare Tire Delete design lets you mount a full air system and train horns in a location that is already designed to carry weight and hardware. On Super Duty trucks like Skyler's 2015 F250 Lariat, it keeps the horns and tank protected, maintains ground clearance, frees up bed and frame space for towing or hauling, and gives the truck a cleaner, more aggressive look while making maintenance and access to the under-bed area much easier.

The 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. Full-size trucks like the 2015 Ford F250 Lariat typically have no problem supporting this type of onboard air system.
