Tuyoung Under-Seat Storage Boxes for Chevy Silverado 2019-2026 — Molded ABS, Modular Dividers

The Tuyoung under-seat storage boxes are a rugged, custom-fit organizer set that tucks beneath the rear seats of 2019–2026 Chevy Silverado and compatible GMC Sierra trucks to keep tools and gear out of sight yet within reach.

If you drive a Silverado 1500 (2019–2026) or a Silverado/Sierra 2500HD or 3500HD (2020–2026), these molded ABS storage boxes use the otherwise wasted space under the rear seat to secure roadside equipment, cleaning supplies, hunting gear, clothing, and other loose items. The units are built to resist impact and daily wear while offering modular dividers so you can adapt the layout to the items you carry most.

How will these under-seat boxes change my truck’s storage setup?

They convert hidden under-seat cavities into organized, lockable compartments so loose items no longer slide around the cab. Because the components are solid ABS and fit the specified model years, they sit flush under the seat and maintain a factory-like appearance.

• Encloses tools and gear in purpose-shaped compartments to prevent rattling.
• Concealed placement improves security and reduces clutter in the cabin.
• Durable construction stands up to repeated loading and unloading.

Will these fit my specific Silverado or Sierra model?

The set is compatible with Chevy Silverado 1500 trucks from 2019–2026 and Silverado/Sierra 2500HD and 3500HD models from 2020–2026. There is one important exception: it does not fit the 2019 1500 LT/LD variant, and some factory rear floor liners may need trimming for installation.

• Check your truck’s model year and trim before ordering.
• 2019 1500 LT/LD models are excluded from compatibility.
• Vehicles with OEM rear floor liners might require minor trimming for a flush fit.

What features make these boxes durable and flexible for different cargo?

Constructed from high-strength ABS plastic, the storage boxes resist impacts, retain shape, and tolerate temperature swings commonly experienced inside trucks. The multi-compartment layout plus removable dividers lets you tailor the interior to small tools or bulkier items as needed.

• High-toughness ABS material for long-term durability.
• Multiple fixed compartments for separation and organization.
• Removable, repositionable dividers allow custom layouts.

How easy is installation and maintenance?

Installation is straightforward for most owners: slide the molded boxes into the under-seat area and secure per the included guidance; trimming may be required if your truck has factory floor liners. Maintenance is simple—wipe clean with mild soap and water to remove dirt and spills.

• Simple slide-in installation; no permanent modifications for most trucks.
• Minor trimming only when factory floor liners obstruct fitment.
• Easy-clean ABS surface—wipe down as needed.

Who this is for: The Tuyoung under-seat storage boxes are a practical upgrade for Silverado and Sierra owners who want to tidy the cabin, protect tools and gear from damage or theft, and use every inch of their truck intelligently. They're well suited to tradespeople, outdoor enthusiasts, hunters, and anyone who hauls loose items and prefers a secure, out-of-sight solution that keeps the interior organized without permanent modification.
