ACS ROOF: The Modular, No-Drill Roof Rack for Your Lexus GX550

A low-profile, no-drill 3/4 platform rack with infinitely adjustable load bars — engineered specifically for the Lexus GX550 and built to expand as your gear does.

No-drill, bolt-on install. Comes with all mounting hardware.

✓ No-drill, bolt-on — adds just 4 inches to your GX550's height, with no permanent modification.
✓ 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.
✓ Shark fin antenna compatible — the rear load bar is designed to clear your antenna at a low profile and protect it from impacts.
✓ 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 the roof of your Lexus GX550. It's a modular, no-drill 3/4 platform rack with infinitely adjustable sliding load bars, built stronger and lighter than typical roof rack systems, and easy enough to assemble yourself.

Every ACS ROOF is over-engineered and over-built in Corona, California, with Grade 10.9 black Zi-Ni fasteners, a dual-stage powder coat finish, and a low 4-inch profile that keeps your GX550 looking factory-clean. Removable corner caps make auxiliary lighting installation simple, and the rear load bar is shaped to clear your shark fin antenna.
