M.A.S.S. Storage Drawer – 6 Inch (6×3 Pattern)

Build your cargo system like a set of building blocks

The 6-inch M.A.S.S. Storage Drawer is designed to be a true module in a larger system, not a one-off drawer that locks you into a single layout. It bolts into the M.A.S.S. ecosystem with a standardized mounting pattern so you can stack, shift, and expand your setup over time as your needs evolve. If you want the deep dive on how the platform, rails, and modules all work together, check out the full M.A.S.S. overview here: M.A.S.S. System Info.

Heavy-duty slides, smooth operation, lifetime backing

This drawer runs on lifetime-warranty locking drawer slides rated at 500 lb. Load it with tools, recovery gear, kitchen kits, camera cases, or whatever your rig needs, then lock it in or out so it stays exactly where you put it.

---

Lightweight, corrosion resistant, and built to last

The drawer body is built from 5052 aluminum to save weight, resist corrosion, and hold up to years of real use. No swelling, no warping, no “soft” edges, and no moisture issues. It is a durable foundation for an overland drawer stack that you can keep building on.

Modularity highlights

• Designed to stack and expand: Standardized hole pattern makes it easy to add drawers, sliders, and accessories over time.
• Two removable dividers included: Quickly organize tools, straps, parts, or recovery gear (and reconfigure later).
• Lock-in / lock-out operation: Keeps the drawer secure on steep climbs, off-camber trails, or daily driving.
• Mounting everywhere: Built for real add-ons like slides, cargo boxes, and accessory panels.
• Universal applicaions: The attachment pattern on the bottom mounting flanges of the drawers is a 7mm (~0.28″) hole every 1″. This ensures a large amount of flexibility for mounting needs. These drawers can be mounted to almost anything!

HD MASS Connectors

If you would like to attach additional modules (more drawers, sliders, etc.) to the top of this drawer, you will need to use our HD MASS Connectors. If you want to attach this drawer to one of our normal MASS Platforms (not MASS+) you will need to use the HD MASS Connectors to do that as well. These are universal drawers and are often installed into non-standard applications, so the connectors are not included with the product. HD MASS Connectors are sold separately. The HD MASS Connectors can be added to your order by checking the box above under “Frequently Purchased Together”.
