Under Seat Storage Boxes for 2019-2025 Silverado/Sierra - Hidden Cargo

Our review of these under seat storage boxes finds them best suited for owners of 2019-2025 Chevy Silverado 1500 and GMC Sierra 1500, and 2020-2025 Silverado/Sierra 2500HD/3500HD with crew or double cabs who need tidy, hidden cargo space. The single biggest reason to buy is straightforward: they convert wasted under-seat space into a durable, partitioned storage solution that keeps tools and accessories organized and out of sight. Installation is simple for most trucks, and the ABS construction feels solid for long-term use.

Key Features

• Vehicle Fitment: Designed specifically as direct replacements for 2019-2025 Silverado 1500 and 2020-2025 Silverado/Sierra 2500HD/3500HD crew and double cab rear under-seat openings for a tailored fit.
• Durable Material: Constructed from high-grade ABS plastic to provide rigidity and impact resistance for everyday items stored beneath the seat.
• Hidden Extra Storage: Makes use of otherwise wasted under-seat space to stow jumper cables, wheel tools, cleaning supplies, hunting gear, shoes, and clothing out of sight.
• Partition Design: Internal dividers keep gear separated so small items do not roll together, helping maintain a tidy truck interior.
• Removable Baffle: A removable partition allows quick reconfiguration to accept larger or irregular items when needed.
• Warranty Commitment: Backed by a 12-month warranty so buyers have recourse if fitment or material issues arise.

Who It's For

This accessory is ideal for Silverado and Sierra owners who frequently carry tools, recovery gear, or personal items and prefer them concealed under the rear seat rather than in open-bed bins or visible cab storage. The molded ABS construction and partitioning suit people who want a durable, organized solution that integrates cleanly under the factory seat.

It is less suitable for trucks that already have factory-installed rear floor liners that cannot be trimmed or for owners who need larger under-seat drawers with locking lids; this product is an open box-style storage solution and may require minor trimming of liners for fitment.
