Frequently Asked Questions
Which 4Runner models does this platform fit?
It fits the 2025+ 6th Gen Toyota 4Runner (2-row, non-hybrid). It does not fit hybrid (i-FORCE MAX) configuration.
What makes this cargo platform different from others?
The AAL MASS Platform is built entirely from 5052 aluminum, not plywood. It’s lighter, stronger, and fully corrosion-proof — designed to handle real off-road use without warping or cracking.
How much weight can the platform hold?
It easily supports typical overland loads (250–400 lb distributed) including drawers, fridge slides, or gear bins. The 3 mm aluminum deck and steel brackets prevent sag or flex under load.
What finish options are available?
Choose Raw Aluminum (lightweight DIY finish), Mil-Spec Black, or Textured Black Powder Coat.
How heavy is the entire system?
Roughly 35–45 lb, depending on door configuration — about half the weight of comparable plywood systems. That saves payload capacity and improves handling.
Does aluminum make it noisier than wood?
Quite the opposite. Wood can dry, shrink, and creak; our aluminum panels remain dimensionally stable in heat, cold, and humidity — keeping your cargo area silent and secure.
Will the platform corrode or rust?
Never. 5052 aluminum is marine-grade and naturally corrosion-resistant. Combined with powder coat or Mil-Spec finish, it outlasts any plywood or mild-steel alternative.
Can I mount an air compressor or auxiliary battery underneath?
Yes — the Fixed Door version provides under-deck space perfect for auxiliary systems like air pumps, power modules, or recovery gear.
Is any drilling or cutting required during installation?
No. The MASS Platform bolts directly into factory mounting points using basic hand tools. No permanent modification is needed.
Why does the product specify “Non-Hybrid”?
Hybrid (i-FORCE MAX) models have high-voltage battery components under the rear cargo floor. This platform’s mounting geometry is specific to the standard gasoline model’s flat cargo deck.
Does aluminum rattle on rough trails?
No. The platform uses precision-cut panels, anti-vibration fasteners, and steel mounts, resulting in a solid, rattle-free deck that stays quiet even after thousands of trail miles.
Can I install drawers or a fridge slide on top?
Absolutely. The MASS Grid pattern accepts AAL drawers, fridge slides, and tie-down plates directly — no extra brackets required.
What access-door options can I choose?
Two styles — Fixed Access Doors (for permanent gear setups) or Removable Latched Doors (for easy storage access).
Can the platform be removed if I sell the vehicle?
Yes. It’s a bolt-in system, so you can return the cargo area to stock in minutes.
How long does installation take?
Typically 1–2 hours. All mounting hardware is included, and everything lines up with OEM mount points.
Why does weight matter in an overland platform?
Every saved pound improves fuel economy, braking, and suspension response. The 5052 aluminum deck keeps weight low while maintaining exceptional strength.
