Jeep Wrangler JL 2-Door Storage Platform
The MASS+ Platform for Jeep Wrangler JL 2-Door is a rigid, waterproof foundation for overlanding and everyday utility. Built from 3 mm (1/8″) 5052 aluminum with a 3 mm carbon-steel support structure, it delivers exceptional strength-to-weight, a perfectly flat deck for modules, and hundreds of threaded mounting points for drawers, sliders, tie-downs, fridge plates, and more. It bolts directly to factory-threaded holes — no drilling or trimming — and rides about 3/4″ above the rear plastic for a clean, OEM-level fit that retains access to the cargo cubby below. Choose from Raw/Unfinished for DIY projects, Textured Black for a durable powder-coated finish, or Textured Black with Mil-Spec top plate coating for the best combination of durability, anti-skid traction, and sound damping.

Why aluminum mass+ Beats Plywood Platforms
Many cargo platforms are built from plywood or wood-core composites. They can work, but they come with tradeoffs: weight, susceptibility to moisture, and limited modularity without drilling. The MASS+ Platform solves those issues with a purpose-built aluminum + steel structure engineered for the JL 2-Door.| Factor | Typical Wood / Plywood Platforms | MASS+ Aluminum Platform | Why It Matters (JL 2-Door) |
|---|---|---|---|
| Weight | Heavier panels and braces; adds strain and reduces payload. | ~55 lb with engineered structure for strength-to-weight. | Lighter system = more capacity for gear and easier installs. |
| Moisture & Weather | Can swell, warp, or delaminate; may require sealing/maintenance. | Waterproof 5052 aluminum + coated steel; no swelling or rot. | Trail-proof in rain, mud, and snow with minimal upkeep. |
| Rigidity & Flatness | Needs thick panels/cross-braces; can flex over time. | Laser-cut aluminum deck + steel support stay flat and rigid. | Drawers/sliders track true; fewer rattles and adjustments. |
| Mounting & Modularity | Often requires drilling/cutting for tie-downs and modules. | Integrated threaded holes across platform for direct mounting. | Faster builds; no guesswork or field mods. |
| Installation | May require drilling, rivnuts, or interior trimming. | True bolt-in to factory threaded holes; no drilling or trimming. | Cleaner install; preserves OEM panels and resale value. |
| Longevity | Wood finishes wear; damage can propagate with moisture. | Aluminum + powder coat / Mil-Spec top plate = long service life. | Lower maintenance, premium look for years. |
| Factory Cubby Access | Often blocked or requires cutouts. | Design maintains access to the cargo cubby underfloor. | Keeps OEM storage usable for small items and recovery gear. |
