Jeep JLU M.A.S.S. Cargo Shelf - Adjustable Height
Your Jeep JL has plenty of capability – but not always plenty of space. Our MASS Cargo Shelf changes that.
Built from lightweight but strong 5052 aluminum, this shelf bolts into your JL to create a second level of storage in the cargo area. Whether you’re hauling camping gear, recovery tools, or the week’s groceries, the MASS Cargo Shelf keeps it all organized and off the floor, while still leaving room underneath for coolers, bins, and the bulky stuff.
It’s not just storage – it’s part of our MASS (Modular Adaptable Storage System) line, meaning you can mount other accessories right to it. From overlanding to weekend errands, this shelf makes your JL a smarter, more capable machine.
Key Features:
-
Maximize Your Cargo Space – Adds a second tier for smarter packing.
-
JLU-Specific Fit – Designed exclusively for the Jeep JLU Wrangler.
-
5052 Aluminum Construction – Lightweight, strong, and corrosion-resistant.

If you’re tired of gear piles in your JL, this is your answer. Pack more. Pack smarter.

Jeep JLU M.A.S.S. Cargo Shelf - Adjustable Height
Soft Top Fitment
This was designed for the JLU hard top, but will work well with the soft top. Here are some photos of it installed in our JLU with the soft top. There are also some details about fitment.
Multiple Materials
We combine three different materials to provide ultimate strength and still keep it as light weight as possible.
- 1/8″ steel for the vertical supports that attach to the roll bar for superior strength and lateral stability.
- 1/8″ steel for the side spreaders. This ensures that the platform parts are able to strong over the entire span of the shelf.
- 1/8″ aluminum for the platform parts. This is where we can save some weight. Due to the mounting method, we are able to reduce the weight of the largest components in the rack.
- 1/8″ steel for the vertical, under-platform supports. Here’s where we got fancy. The vertical steel supports bolt in and provide a huge amount of vertical strength.
- 1/8″ steel for the edge guards to provide maximum strength for securing cargo.
