KitsPro Under-Seat Storage Box for Ford F-150 SuperCrew & F-250/F-350 (18-Gallon) — Heavy-Duty Waterproof Organizer

KitsPro's 18-gallon under-seat cargo box is a heavy-duty, waterproof organizer custom-made to fit 2015–2026 Ford F-150 SuperCrew and 2017–2026 F-250/F-350 Super Duty crew cabs.

This modular rear-cargo system consolidates four interlocking compartments into a single, rigid storage solution that lives under the back seat. Built from thick ABS with a textured anti-slip finish and shaped from 3D laser scans of compatible Ford truck floors, it holds tools, recovery gear, fishing rods, and everyday clutter securely while allowing factory seat operation and floor mat fitment.

How does the KitsPro box fit my Ford truck?

The organizer uses a 3D laser-scanned profile tailored to 2015–2026 F-150 SuperCrew and 2017–2026 F-250/F-350 Super Duty crew cabs, ensuring tight contours around subwoofers and factory mats. Installed under the rear seat, it does not alter seat folding or locking functions.

• Precision fit for the listed model years and crew cab configurations
• Works with factory floor mats and common subwoofer placements
• Rear seats fold and lock normally after installation

What makes this storage waterproof and durable?

Constructed from high-impact ABS, the unit resists warping from sun exposure and sheds mud or spills with a hose. The textured matte finish reduces movement noise and keeps items from sliding during transit.

• Thick ABS resists heat-related deformation and years of use
• Waterproof, washable surface — rinse clean with a hose
• Anti-slip texture reduces rattles and item movement

How is the kit organized and what accessories are included?

The system is four interlocking 18-gallon modules that bolt together into one 68-liter organizer and includes three foam divider panels with molded cutouts. Hardware and tools for a no-drill installation are supplied, plus an illustrated guide and QR-linked installation video.

• Four bolt-together modules create a single, rigid storage box
• Three foam dividers cushion and secure long or fragile items
• All screws, socket, screwdriver, and manual included — no drilling

Will installation require drilling or special tools?

No drilling is needed. KitsPro supplies every screw and driver required to fasten the assembled unit to factory mounting points, with step-by-step instructions and optional video support for a straightforward install.

• No-drill mounting to existing factory points
• Complete hardware kit and matching tools included
• QR code links to a step-by-step video for guidance

Who is this for? This under-seat organizer is aimed at Ford truck owners who use their crew cab for work, outdoor recreation, or daily hauling and want a low-profile, durable storage solution.
