Tyger Auto Rear Under-Seat Storage Box for 2019–2026 Silverado & 2020–2026 Sierra, Textured Black, Custom-Fit

A custom-fit under-seat cargo box that tucks neatly beneath rear seats of compatible Silverado and Sierra trucks to add secure, organized storage without modifying the interior.

This Tyger Auto Rear Under Seat Storage Box (model TG-CB5C8838) is engineered to fit specific cab configurations of the 2019–2026 Chevrolet Silverado and 2020–2026 GMC Sierra trucks. Made from injection-molded polypropylene with a textured black finish, the unit installs under the rear bench and provides removable dividers, a mesh net for small items, and a buckle strap to lock the box into place for a factory-like appearance and stable carry. It’s designed for drivers who need extra hidden storage for tools, gear, or personal items without altering factory carpeting or seat mounting.

How do I know this fits my Silverado or Sierra?

Fitment depends on model year and cab type: the box is intended for select 2019–2026 Silverado 1500 and 2020–2026 Silverado/Sierra 2500HD and 3500HD models with extended/double or crew cabs that have two full-size front doors and two rear doors. It will not fit LD/Limited 2019 models or trucks with factory floor mats that interfere with the unit.

• Confirm fit using the vehicle lookup tool on the product page.
• Compatible with Double Cab and Crew Cab configurations only.
• Not compatible if factory floor mats obstruct under-seat space.
• Check your model year against the listed ranges before purchase.

What materials and construction make this storage box durable?

The box is injection-molded from impact-resistant polypropylene, a step up from basic thermoformed alternatives. This manufacturing method yields a precise, rigid structure that resists cracking and maintains its shape under weight and daily use.

• Premium injection-molded polypropylene for toughness and longevity.
• Textured black finish for a factory-matched look that resists scuffs.
• Solid molding delivers consistent dimensions for a snug fit beneath seats.
• Includes a buckle strap to secure the box and prevent shifting while driving.

How is the storage organized and what can I store?

Interior organization is flexible: removable dividers let you partition the cavity for larger items or create smaller compartments for tools and supplies. A detachable mesh net keeps small loose items from rolling around, and the divider layout can double as a practical rack for long items when needed.

• Removable dividers for custom compartment sizes.
• Mesh net secures small items like chargers, gloves, or first-aid supplies.
• Dividers can be arranged to support long gear or act as a basic rack.
• Concealed placement under the rear seat keeps valuables out of sight.

How easy is installation and maintenance?

Installation is straightforward and reversible: slide the box under the rear bench, route the provided buckle strap, and snap it into place for a snug, factory-like fit. Maintenance requires only occasional wiping—polypropylene resists stains and is simple to clean with a damp cloth and mild detergent.

• Tool-free installation using the included buckle strap.
• Removable components make cleaning simple and quick.
• Designed for a snug fit to prevent rattles or movement during driving.
• Backed by a 3-year Tyger Auto warranty against manufacturing defects (U.S. customers).

Who is this for: Drivers who own compatible Chevrolet Silverado or GMC Sierra trucks and want concealed, organized storage under the rear seat—professional tradespeople, outdoor enthusiasts, and everyday commuters who need tidy, secure cargo space without permanent vehicle alterations. If you need a durable, manufacturer-quality solution to keep tools, gear, or valuables out of sight and well organized, this Tyger Auto unit is built for that purpose.
