In this review the ECOTRIC underseat storage box is judged on fit, durability and usefulness for crew cab owners who need low-profile organization. The bottom line: it is a practical replacement set that turns the unused space beneath Silverado and Sierra rear seats into secure, out-of-sight storage. Reviewers found the installation straightforward and the construction solid, making it a compelling option for owners who want to stow tools, fishing gear or valuables without altering cabin appearance.

Key Features

• Vehicle-specific fit: Custom molded to fit 2007-2018 Silverado and 2007-2019 Sierra Crew Cab models, so placement under the rear seat is snug and stable.
• Durable construction: Made from high impact molded automotive grade plastic to resist dents and hold up to camping, worksite or wet conditions.
• Large storage capacity: At approximately 54-1/2 in wide by 16-1/4 in deep the set provides substantial room for tools, a jack, or outdoor gear while leaving access to underseat areas.
• Complete kit: Ships as an 8-piece set with nets and installation hardware so buyers receive everything needed for a direct replacement install.
• Concealed security: Places valuables in an inconspicuous location under the seat to reduce visual clutter and protect items from casual view.

Who It's For

This underseat storage box is aimed at owners of Chevrolet Silverado (2007-2018) and GMC Sierra (2007-2019) Crew Cab trucks who want a durable, factory-style replacement for the original underseat container or an upgrade for better organization. It suits tradespeople, anglers, hunters and anyone who carries tools or equipment and prefers to keep them out of sight.

Buyers with newer Silverado 2019 models or non-crew cab configurations should look elsewhere since the fit is not compatible with those vehicles. Those who need internal dividers should note dividers are not included and must be sourced separately.
