ACS ROOF: The Low Platform Rack Over Your Tonneau Cover

A low-profile platform rack that mounts over your tonneau cover — infinitely adjustable load bars, side-access storage ready, and built to expand your cargo setup.

Low platform rack that mounts over a tonneau cover using the tonneau's mounting hardware. Comes with all mounting hardware.

✓ Mounts over your tonneau cover — a low-profile platform that installs over the tonneau, keeping your bed covered while adding cargo capacity.
✓ Modular, adjustable load bars — slide into toothed channels so you can reposition gear or add bars as your setup grows.
✓ Cross-brand compatible — works with T-track accessories from Thule, Rhino-Rack, and Yakima.
✓ Side-access, lockable storage ready — pairs with the GearPOD ROOF side-opening, water-resistant, locking storage box.
✓ Expandable platform — add more load bars to build out a solid, flat cargo surface as your needs grow.

Why ACS ROOF

ACS ROOF brings 10 years of Active Cargo System engineering — and hundreds of thousands of off-road testing miles — to your truck bed. It's a modular platform rack with infinitely adjustable sliding load bars, built stronger and lighter than typical rack systems, and easy enough to assemble yourself. This low platform mounts over your tonneau cover so you keep the bed covered while adding a cargo surface up top.

Every ACS ROOF is over-engineered and over-built in Corona, California, with Grade 10.9 black Zi-Ni fasteners and a dual-stage powder coat finish. Add the GearPOD ROOF for side-access, lockable, water-resistant storage without climbing onto the rack.

Frequently Asked Questions

See all FAQs →

How does this rack mount over a tonneau cover?

It's a low platform rack that installs over your tonneau cover, secured using the tonneau's mounting hardware, so you keep the bed covered while gaining a cargo surface on top.

What is the load capacity?

It's rated at 800 lbs static and 400 lbs on-road. Because the rack is secured through the tonneau's mounting hardware, we can't recommend a safe off-road weight limit for this configuration. Always confirm your vehicle manufacturer's bed load rating as well.

Why isn't there an off-road rating?

The rack anchors to the truck through the tonneau cover's mounting hardware rather than directly to the bed, so we don't publish a safe off-road weight limit for this setup. If you need off-road capacity, consider our over-bed or bed-rack mounted ACS ROOF options.

Can I add lockable, water-resistant storage?

Yes, with the GearPOD ROOF accessory — a nearly 96-quart, side-opening storage box with locking handles and a water-resistant seal.
