Build Your Jeep Cargo Setup on a Modular Foundation
The Jeep JL M.A.S.S. Storage Platform gives compatible drawers, slides, and tie-downs a common mounting surface. Start with the platform, then arrange the cargo area around the gear you carry.
Choose the platform for your Jeep before choosing modules: non-4xe uses a 6×4 pattern, while the shorter 4xe platform uses 6×3.
Made in the USA. Built in St. George, Utah.
We manufacture the Jeep JL M.A.S.S. Storage Platform right here in our St. George, Utah shop. American-made parts, straight from our shop to your Jeep.
Choose the Right Platform Pattern
Non-4xe: 6×4
The standard platform provides a 6×4 pattern in each module column. Use a 6×4 base slide where appropriate, or choose compatible 6×3 modules for a shallower setup.
4xe: 6×3
The 4xe battery compartment reduces the available cargo-floor space. Its shorter platform uses a 6×3 pattern. Choose compatible 6×3 base modules for this version.
Plan for the Rear Seat Angle. The mounting pattern at the floor does not guarantee clearance higher in a stack. On non-4xe Jeeps, 6×4 base slides can fit at floor level, while 6×3 drawers provide clearance for the rear seat angle.
Connect Modules and Tie Down Cargo
HD M.A.S.S. Connectors
Use HD M.A.S.S. Connectors to attach compatible drawers and slides to the platform. HD M.A.S.S. Connectors are sold separately.
For non-4xe builds, explore the 6×4 Fridge Slider, 6×4 Flat Slide or 6×4 Flip’n Slide. For 6×3 layouts, see the 6×3 Flat Slide and 6-Inch Drawer (6×3).
L-Track Connection Options
The platform cutouts accept standard L-track-style fittings for tie-down setups. The module mounting pattern lets you reposition compatible M.A.S.S. components as your cargo needs change.
The JL Slightly Wider Slider uses the JL-specific off-pattern location shown in the non-4xe diagram. Confirm the platform and module combination before ordering.
Aluminum Platform, Recessed Hardware
The platform panels are laser-cut from 1/8-inch 5052 aluminum and supported by three fabricated support rails. Recessed bolt heads keep the cargo surface clear for loading and unloading.
Fitment and Installation
Two-Door Installation Requires Drilling. The frontmost two mounting inserts are covered by a thin layer of body sheet metal. The installation requires locating those inserts and drilling through the covering sheet metal to access them. Review the installation information before starting.
The installation guide covers removal of the OEM cargo tie-down hooks and carpeted cubby lid, plus the rear-seat crack cover where fitted. Review the guide for your platform version and vehicle configuration.

Finish and Build Planning
Choose from the available raw and powder-coated finishes. Raw aluminum lets you handle your own finishing plans. Powder coat options are not exact factory paint matches; review our powder coat information before selecting a color.

Frequently Asked Questions
Do I need specific rails if I am using the 100ah Li-time Battery Mount?
Yes, you can purchase it through this link https://americanadventurelab.com/product/jeep-wrangler-jlu-mass-platform-support-rail-litime-100ah-mini-battery-cutouts/
How much does the Platform weigh?
The platform weighs 36 lbs
Do I have to powder coat this?
You can purchase this raw, however we suggest powder coating the rails and any steel components to help keep them from rusting. For all raw components there will be machine marks from manufacturing and possibly from shipping so if scratches and machine marks bother you, then we suggest powder coating the platform.
Can I attach other slides and items straight to the platform that are not made by AAL?
Yes! Our platform provides you with more mounting possibilities than your original equipment. It is as simple as drilling holes to match up with the product in question at your own discretion.
Will it work with a 2 door JL?
It will, you will have to take out your back seats and it will require larger Nutserts/bolts. We do however have a specific Platform for the 2 door.
What is it made out of?
The base plate of the platform itself is made of 0.122” Aluminum with steel rails that fasten to both the jeep and the base.
Do I have to drill any holes to install this?
On the JL, no! We use all factory bolt holes to install the rails.
Which powder coating is best for the platform?
The majority of our customers purchase Textured black for the platform as it is a less aggressive version of linex, it seems to withstand more than the other coating options however is not impervious to scratches.
Can I keep the cargo area carpet if I use your platform?
You will need to remove the cargo area carpet to install the platform.
Does this limit access to the cubby underneath the Cargo area?
Yes, it does which is why we created the MASS Plus Platform! However, if you prefer our original version of the Platform, you can utilize our Dual ARB compressor mount for the JL rear cargo area and our remote kit to fill the area without having to access it!

Just installed the storage platform in a 2021 Jeep Wrangler 4xe. Install was super easy and quick. One thing to note on the install instructions is that step one (remove the back seat crack cover) was not needed with the 4xe model. The platform fits perfectly right up against it.
