DVA DualTrack-T™ MAX (Gen 2) Cross Bars — INEOS Grenadier
Turn your Grenadier’s roof into a fully modular platform. Each low-profile 6061-T6 aluminum bar carries two mounting standards at once — a full-length row of L-Track plus a 25mm T-Slot — so tents, awnings, solar, recovery boards, cargo boxes, and Starlink mounts all bolt on without adapter plates and without drilling. At about a 1″ profile it sits below the gutter line and still clears a standard 7-ft garage door.

| Mounting | Full-length L-Track + 25mm T-Slot (per bar) |
| Bar length | 58.5 in (149 cm) |

Do I need adapter plates?
No — each bar has a full-length L-Track row plus a 25mm T-Slot, so L-Track hardware and 25mm T-Slot hardware both drop straight in and lock anywhere along the rail.
Which kit do I need for a rooftop tent?
The 4-rail kit — it adds front, two center, and rear bars and is rated to 600 lb static / 300 lb dynamic. The 2-rail kit (300/150) suits awnings and lighter cargo.
Will my Grenadier still fit in the garage?
The bars sit at about a 1-inch profile and are designed to clear a standard 7-foot garage door, depending on what you've mounted on top.
Does it require drilling?
No — it bolts to the Grenadier's factory roof attachment points in about 45 minutes and is fully reversible.
Does it fit the Quartermaster?
Yes — it's confirmed to fit both the Grenadier Wagon and the Quartermaster, 2023 to present.

Does installation require drilling?
No. The bars bolt to the Grenadier's factory roof points in about 45 minutes and the install is fully reversible.
What are the bars made of and how tall are they?
Each bar is 6061-T6 aluminum, 58.5 in (149 cm) long, with a profile of about 1 in (2.5 cm). That sits below the gutter line and is designed to clear a standard 7-ft garage door.
Which Grenadier models does this fit?
