One of the biggest challenges with the Jeep Wrangler JL is making efficient use of the cargo area without sacrificing accessibility, visibility, or rear-seat functionality.
Traditional drawer systems can be heavy and permanent, while loose gear often ends up stacked on the cargo floor with limited organization.
We wanted a better way to maximize the space already available inside the Jeep.
The American Adventure Lab M.A.S.S. Cargo Shelf creates a strong, adjustable second level of storage in the rear cargo area of the Jeep JLU, allowing you to separate gear, improve organization, and secure cargo for everything from daily use to extended overland travel. Designed around the M.A.S.S. ecosystem, it provides nearly unlimited tie-down options while keeping your cargo area flexible and adaptable.
Features & Benefits:
• Designed specifically for the Jeep Wrangler JLU (4-door)
• Creates a raised storage platform above the cargo floor
• Adjustable height design to accommodate different gear configurations
• Lightweight yet durable 5052 aluminum construction
• Approximate shelf weight: 30 lbs
• Dogbone cutout pattern provides nearly unlimited cargo tie-down options
• Compatible with Mac's Single Stud Tie-Down Rings and strap systems
• Helps organize camping gear, recovery equipment, tools, refrigerators, and storage bins
• Maintains usable storage space underneath the shelf
• Compatible with many M.A.S.S. accessories and cargo management components
• Available with optional MOLLE Bulkhead integration for additional organization
• Designed and manufactured in St. George, Utah, USA
Installation Notes:
• Mounts directly to the factory roll bar structure
• Adjustable mounting positions allow you to tailor storage height to your needs
• Installation requires basic hand tools
• No custom fabrication required
• Works with both hard top and soft top configurations
• Designed for JLU (4-door) applications only at this time
