PRECISION FIT — CHECK YOUR CAB STYLE: 3D laser-scanned for 2015-2026 F-150 SuperCrew/Crew Cab and 2017-2026 F-250–F-550 Super Duty Crew Cab. 4 full-size doors only. Not for Regular Cab or SuperCab. Clears factory floor mats. Confirm your year and cab style before ordering.
BUILT FOR LONG GEAR — CHECK YOUR SETUP: Three pre-trimmed foam divider panels with cutout channels hold rifles, shotguns, and tools in place. No shifting on rough trails. No rattles. No damage. Note: If your truck has a factory subwoofer under the rear seat, it may interfere with installation. Check your underseat layout before ordering.
HIDDEN & SECURE: Sits completely under the rear seat. When the seat is down, nothing is visible from outside. No prying eyes. No clutter. Your truck stays clean and low-profile — whether you're parked at the trailhead or the job site.
RUGGED ABS — WASH IT OUT: High-impact ABS with textured matte black finish. Won't warp under cab heat. Won't crack under heavy loads. Anti-slip surface keeps gear planted. Waterproof — pull the whole box out and hose it down after a muddy hunt.
NO-DRILL ASSEMBLY — EVERYTHING INCLUDED: Four modular ABS panels bolt together with included hardware. Torque wrench, screwdriver, and gloves in the box. No drilling into your truck. Illustrated guide walks you through it. If anything fails, we'll send a replacement — no expiration.

What if my truck has a factory subwoofer?
The factory subwoofer sits under the driver-side rear seat on some F-150 trims. It occupies that space, so the box won't fit on that side without modification. Check your underseat layout before ordering.
Will it keep long gear hidden and protected?
Yes. Sits completely under the rear seat — nothing visible from outside. Three pre-trimmed foam panels hold rifles and shotguns tight. No shifting on rough trails. No rattles. Purpose-built, not adapted.
Can it handle mud, rain, and rough use?
High-impact ABS, textured matte black. Won't warp under heat or crack under load. Waterproof — pull it out and hose it down after a wet hunt.
