Grenadier Crossbars: OEM Gutter-Clamp vs. DVA DualTrack
Externally verified specifications, decision points, and limits for the exact vehicle and configuration.
Vehicle Limit and Carrier Limit Are Different
The vehicle roof rating is not permission to load a carrier to that number. Compare the exact vehicle handbook, the bar or rail system, every mount, and the accessory. The lowest documented limit governs, and carrier mass counts.
Current DualTrack-T MAX Gen 2
DVA's rendered product page specifies 6061-T6 extruded-aluminum rails that bolt to the Grenadier's factory roof attachment points without drilling. Each rail provides an L-Track channel and a 25mm T-slot channel. The 2-rail system is rated 150 lb dynamic/300 lb static; the 4-rail system is rated 300 lb dynamic/600 lb static; and the Wagon-only 6-rail system is rated 330 lb dynamic/900 lb static. The Quartermaster uses the 2-rail kit over the rear seats.
OEM Crossbars
OEM crossbars are the simpler choice when their fixed bar positions and current INEOS accessory instructions suit the load. Confirm their current cargo rating, fastener torque, and fitment from the instructions supplied for the exact kit; this review does not infer those values from the vehicle roof ceiling.
Which System Fits the Build?
- Choose OEM bars for a conventional two-bar load that fits the documented OEM positions and instructions.
- Choose DualTrack-T MAX when the build benefits from continuous L-Track and T-slot mounting interfaces.
- Use the DVA L-Track collection for compatible tie-down and mounting hardware.
- Review the current DVA catalog rather than relying on retired Gen 1 specifications.
Load Calculation
Add the rails or bars, brackets, accessory, and cargo. Check the total against every published dynamic limit before driving and every static limit before occupying a parked rooftop tent. Do not use the Station Wagon figure for a Quartermaster: the current DualTrack PDP limits the Quartermaster to two rails over the rear seats, and its vehicle roof documentation still controls.
Owner Reality Check
Seems all the full roof racks have at least some mounts that attach to the gutter.

Crossbars or a Full Platform?
| Decision | Crossbar/rail layout | Full platform layout |
|---|---|---|
| Best fit | Defined accessories with documented support points | Mixed cargo that genuinely needs a broad deck |
| Mass accounting | Count every rail, bar, and bracket | Count the deck, perimeter, feet, and accessory mounts |
| Access | Open roof areas remain reachable | Broad coverage may simplify cargo placement only when its maker permits it |
| Verification | Check accessory span and bar requirements | Check platform footprint, attachment map, and every rating |
Choose crossbars when
The cargo is one or two defined accessories, their makers publish compatible support positions, and the complete rail/bar/bracket mass stays inside every vehicle and system limit. Crossbars also make sense when open roof area and easier removal matter more than a continuous deck.
Choose a full platform when
The trip load changes regularly or truly needs a broad supported surface, the platform maker documents the intended point loads and restraint method, and its added mass still leaves adequate payload. A platform is not automatically stronger, and crossbars are not automatically lighter after adapters are counted.
Worked accounting method
Let R equal the documented installed mass of the rails/platform, A the mounted accessories, and C the trip cargo. The moving total is R + A + C. Compare it with the vehicle ceiling and system ceiling; the lower number governs. For a six-rail Wagon system, both published moving ceilings are 330 lb, but no net cargo figure is defensible until R and A are documented. For parked occupancy, repeat the calculation with people and every item on the roof against the parked ceilings.
Three practical cases
- One fixed accessory: begin with the smallest documented support layout that satisfies the accessory instructions and every limit.
- Accessories that change by trip: prioritize a repeatable interface and record the approved hardware for each item.
- Broad loose cargo: evaluate a platform, but confirm restraint and whether the deck is approved for the intended point loads.
A Second Owner Perspective
I use the OEM for large loads. I leave the DVA on all the time.
