ACS ROOF: The Modular 3/4 Roof Rack for Your INEOS Grenadier A low-profile 3/4 platform rack that bolts to the Grenadier's roll cage with billet aluminum bases — infinitely adjustable load bars, Safari Window compatible, and built to expand as your gear does. 2024+. Bolts directly to the INEOS roll cage via billet 6061-T6 aluminum bases — no reliance on the factory rain gutter. Comes with all mounting hardware. ✓ Billet aluminum mounting bases — machined from 6061-T6 aluminum, they bolt directly to the INEOS roll cage for ultimate strength, not the factory rain gutter. ✓ Safari Window compatible — the 3/4 platform integrates seamlessly with Safari Windows without any interference. ✓ Ultra-low profile — adds just 2 inches to the height of your Grenadier. ✓ Modular, adjustable load bars — slide into toothed channels so you can reposition gear or add bars as your setup grows. ✓ Side-access, lockable storage ready — pairs with the GearPOD ROOF side-opening, water-resistant, locking storage box. ✓ Cross-brand compatible — works with T-track accessories from Thule, Rhino-Rack, and Yakima. 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 INEOS Grenadier. The Platform Rack delivers extreme load-carrying capability thanks to 6063-T6 aluminum extrusion and billet-machined 6061-T6 aluminum brackets that bolt directly to the roll cage. 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. At just 2 inches tall, this 3/4 platform keeps a low profile while integrating cleanly with your Safari Windows.

NOTICE: The 3/4 and full-length platform racks are strong enough to support the heaviest tents, but the low-profile design makes the tent-securing fasteners nearly impossible to reach. For tents, we highly recommend the Roof Load Bar Adapter Kit, designed for hassle-free tent mounting. Download the full installation instructions (PDF) → Frequently Asked Questions See all FAQs → How does the ACS ROOF mount to the INEOS Grenadier? It bolts directly to the Grenadier's roll cage using billet 6061-T6 aluminum mounting bases, so it doesn't rely on the factory rain gutter for strength. Is the 3/4 rack compatible with Safari Windows? Yes. The 3/4 platform integrates seamlessly with Safari Windows without any interference. What is the load capacity on the Grenadier 3/4 rack? It's rated at 1,000 lbs static, 500 lbs on-road, and 250 lbs off-road. Always confirm your vehicle manufacturer's roof load rating, as it may be lower than the rack's capacity. How much height does it add? Just 2 inches — the billet roll-cage mount keeps the Grenadier platform exceptionally low-profile. Can I mount a roof-top tent? Yes, the platform easily supports the heaviest tents. Because the low profile makes the securing fasteners hard to reach, we recommend the Roof Load Bar Adapter Kit for hassle-free tent mounting. Can I add lockable, water-resistant storage? Yes, with the GearPOD ROOF — a nearly 96-quart, side-opening storage box with locking handles and a water-resistant seal, accessible from the side.
