Underseat Truck Storage Boxes, 1 cubic foot

Loose tools and outdoor gear can turn the space under a truck’s rear seat into a jumble. These underseat storage boxes give that area a defined place for everyday items, out of sight when the seat is down.

The three-piece setup includes an extra box and two removable foam dividers. Drop it into place without drilling or tools, then adjust the compartments to suit what you carry.

If you prioritise flexible space for smaller items, the dividers help keep them sorted, if you prefer one open area for bulkier gear, you can remove them. The listed capacity is 1 cubic foot and the system holds up to 25 lbs.

Getting the most from it

Think of it as a way to organise the rear-seat area, rather than a replacement for a large cargo box. Use the compartments for a compact emergency kit, work tools or camping essentials, then remove the foam dividers when an item needs more room. For example, you could keep smaller tools separated on a workday and clear the dividers out when loading larger gear for a weekend trip.

The ABS plastic construction is described as waterproof, with a matte black textured finish. For routine clean-up, the product can be wiped with a damp cloth or rinsed with water. Its drop-in installation is also useful if you want storage without drilling or modifying the truck, the product description says installation takes under five minutes.

Why it’s worth it

The practical appeal is having three compartments in a space that might otherwise collect loose gear. Items can stay together under the rear seat instead of taking up room elsewhere in the cab, and the dividers give you a choice between separation and a more open layout. The textured surface is intended for daily use, while the waterproof material should make dirt or moisture easier to deal with than in an unprotected fabric organiser.

There is a clear trade-off: this is a compact underseat solution, not a high-capacity way to carry heavy equipment. The stated limit is 25 lbs, so it is better suited to everyday essentials and smaller gear than a load of dense tools. It also depends on a precise vehicle fit, and the product is not for trucks with factory-installed floor liners.

The essentials

The storage system is listed for Silverado and Sierra 1500 Crew Cab and Double Cab models from 2019 to 2026, with exclusions for 2019 1500 LD/LT models. It is also listed for 2500HD and 3500HD models from 2020 to 2026, but not 2019 2500HD or 3500HD models. Vehicles with factory-installed floor liners are excluded.

It comes as a three-piece assembly with two adjustable, removable foam dividers and an extra box. The listed capacity is 1 cubic foot, with a maximum load of 25 lbs. Installation requires no tools, drilling or modifications, according to the product details. It suits you if your truck matches the listed cab and year fitment and you want contained storage beneath the rear seat. Better to avoid it if your vehicle falls within an exclusion or you need a storage system for heavier loads.

When to choose it

Choose this setup if you want a dedicated place for smaller work, camping or everyday items and would rather keep them under the rear seat than loose in the cab. Its removable dividers make it more adaptable than a fixed-compartment organiser, while the simple drop-in format avoids permanent changes to the truck.

The main decision is fitment, not just storage style. Check your model year, cab and floor-liner setup against the exclusions before choosing it. If those details match and the 25 lb limit suits what you plan to carry, it offers a straightforward way to keep useful gear organised and tucked away. If you need more volume or a higher load limit, a larger cargo-storage approach would make more sense.
