Jeep Wrangler JKU MASS+ Upgrade Kit

Already running an AAL Jeep JKU MASS Platform? This upgrade kit is the most economical way to step into the MASS+ ecosystem without starting over.

Reuse your existing support rails, then bolt on the new top plates, nut plates, and access doors that add MASS+ connection points and expansion-ready modularity.

Upgrade to MASS+ without replacing your whole system

The MASS+ Upgrade Kit is built for customers who already own our Jeep Wrangler JKU MASS Platform and want the benefits of MASS+ while keeping what they already paid for. You keep the foundation, and swap in the components that unlock the MASS+ “bolt-on anywhere” modular ecosystem.

Why upgrade?

• Most economical path to MASS+ by reusing your existing JKU MASS support rails.
• Expansion-ready top plates and nut plates designed for modular add-ons.
• Cleaner access with updated access doors for quick reach to storage and service points.
• Future-proof your setup so adding drawers, slides, and modules feels like building with LEGO bricks, not rebuilding a platform.

What’s included

• New MASS+ top plates
• New nut plates (MASS+ connection hardware interface)
• New access doors
• Required mounting hardware for the upgrade components (as applicable)

Compatibility

• Vehicle: Jeep Wrangler JKU (2007–2018), 4-door
• Requires: Existing AAL Jeep JKU MASS Platform with support rails already installed
• Not a complete platform: This kit is an upgrade, not a standalone base system

Install overview

This upgrade is designed to integrate with your existing support rails. In most cases it’s a straightforward parts swap using common hand tools. If your platform is an early revision or you’re unsure which version you have, reach out and we’ll help verify fitment before you order.

Perfect for

• JKU owners who want MASS+ modularity without buying a brand-new platform
• Customers planning to add drawers, slides, shelves, compressor mounts, power modules, and future add-ons
• Anyone who wants a cleaner, more expandable cargo foundation

Will this work with every version of the JKU MASS Platform?
It’s designed around the AAL JKU MASS Platform rail system. If you have an older revision, we can confirm compatibility quickly.
