Black Underseat Storage

The WeatherTech Black Underseat Storage box for crew cab rear seating solves a universal problem for truck owners: maximizing usable cargo space without sacrificing passenger comfort. Designed specifically for GM fullsize trucks from 2019–2020, this underseat storage solution tucks compactly beneath rear seats, transforming dead space into secure, weather-protected storage for tools, emergency supplies, recovery gear, or valuables. For mechanics and off-road enthusiasts, this is essential for keeping critical equipment organized and out of sight during work or travel.

Constructed from durable textured black plastic, the WeatherTech design resists moisture, UV damage, and temperature swings—critical for vehicles exposed to daily shop use or outdoor conditions. The reinforced engineering ensures items remain secure during heavy acceleration, braking, or off-road terrain, while the textured finish prevents contents from sliding. At 19 inches wide by 10 inches tall and 60 inches in length, it maximizes the underseat cavity without protruding into legroom, maintaining crew cab functionality. The sealed storage protects sensitive items—spare fluids, electronics, documents—from dust, spills, and humidity that plague open bed storage or traditional toolboxes.

Mechanics and truck owners who regularly transport tools, recovery equipment, or aftermarket parts benefit most from this underseat storage investment. Installation requires no drilling or permanent modification—the box fits directly into the OEM underseat space of GM fullsize crew cabs. Ideal for job-site vehicles, service trucks, or personal use rigs where seat-mounted storage keeps hands-on essentials within arm's reach without bulking up the truck bed or requiring external racks. For 2019–2020 GM crew cab models, this is a straightforward, reversible upgrade that adds professional organization and asset protection.
