Under Seat Storage Box for 2007-2019 Silverado/Sierra - Hidden Storage

In this review the ECOTRIC under seat storage box is evaluated as a practical replacement for Crew Cab owners who need discreet, heavy-duty storage under the rear seat. The single biggest reason to buy is straightforward: it restores and expands usable underseat space with a direct-fit replacement design for 2007-2018 Silverado and 2007-2019 GMC Sierra Crew Cab models. The reviewer found the unit well built from high impact molded automotive grade plastic and appreciated that it uses known replacement part numbers to match factory locations, making it a simple swap for anyone who wants more organized storage without altering the truck interior.

Key Features

• Direct fit: Built to match specific model years and replacement part numbers so installation aligns with factory mounting points for a clean, secure fit.
• Durable construction: Made from high impact molded automotive grade plastic that resists rough cargo and daily wear in work or outdoor use.
• Hidden storage: Sits under the rear seat to conceal valuables, tools, or gear and keep the cabin looking tidy during travel.
• Generous capacity: At approximately 54-1/2 in wide by 16-1/4 in deep it accommodates jack access, toolboxes, and longer items while leaving room for occasional access.
• Complete kit: Ships with the storage box, two nets and an installation kit so most owners have the needed hardware to mount it as a replacement.
• Value: Customers reported heavy-duty feel and a lower price than some competitors, offering practical utility without premium cost.

Who It's For

The box is ideal for owners of 2007-2018 Silverado Crew Cab and 2007-2019 GMC Sierra Crew Cab trucks who want factory-style underseat storage for tools, hunting and fishing gear, or everyday items. It is especially useful for drivers who need a discreet place to stow valuables or free up the cab from loose equipment.

Drivers of 2019 Silverado models should look elsewhere because this unit is explicitly not compatible with that model year. Also, buyers who need internal dividers should note dividers are not included and must be sourced separately for more segmented organization.
