Leitner Designs ACS Full-Length Roof Rack For Ineos Grenadier

If you’re looking to maximize every inch of the Ineos Grenadier’s roofline, this is the rack to run. The full-length ACS platform rack gives you expanded mounting space without compromising on fit or finish. It uses the same custom billet aluminum bases as the 3/4 rack for a factory-grade install and rides just as low and quiet.

We’ve tested both, but the full-length version is ideal if you’re running a larger tent, additional solar, or more gear up top. Thanks to Leitner’s sliding crossbar design, you can still open your safari windows if equipped—just slide the bar forward or back as needed.

Designed and built in the USA, the ACS Full-Length Rack pairs perfectly with our Stealth MAXTRAX Mount for a flush fit that keeps your roofline clean and low-profile, even fully loaded.

Why We Love This

For gear-heavy trips or longer roof tents, the full-length version of the ACS Rack delivers the extra capacity without sacrificing the clean fit and quiet ride we expect from Leitner. The billet aluminum mounts bolt straight to the factory points and feel like OEM. And unlike many full-length racks, this one doesn’t block access to safari windows—thanks to smart, adjustable crossbars. It’s USA-made, built to last, and one of the few we’d actually recommend running long-term.
