If you're choosing between the INEOS-supplied OEM crossbars and DVA's DualTrack™ system for your Grenadier, the short answer is: the DualTrack is the everyday roof platform; the OEM bars are a heavy-duty transport solution for maximum static loads. Both bolt on without drilling, but they mount to entirely different points on the vehicle, carry different dynamic ratings, and suit fundamentally different use cases. Here's the complete breakdown.
DualTrack™ if you want: L-Track accessory mounting, ~1" low profile, 7-ft garage clearance, quiet highway driving, Starlink/recovery gear integration, and a modular platform that grows with your build.
OEM crossbars if you want: Maximum static capacity (795 lb), placement anywhere along the roof gutter, or a side awning mount system that requires the gutter rail design.
Several owners on TheIneosForum run both — DualTrack stays on permanently, OEM bars go on for heavy cargo hauls.
How They Mount — Two Completely Different Systems
This is the most important distinction that most buyers miss. The OEM crossbars clamp to the Grenadier's factory roof gutter rail — the continuous ledge that runs along each side of the roof. You can position them anywhere along that gutter, giving you maximum flexibility in bar placement. The downside: the gutter is an aluminum extrusion that some owners have found susceptible to warping under heavy loads when not properly supported.
The DVA DualTrack™ crossbars take a fundamentally different approach. Each bar bolts directly to the Grenadier's factory roof rail attachment points — the same threaded holes INEOS built into the roof structure for the grab rails. No gutter contact, no clamp pressure, no drilling required. The result is a bolt pattern that ties into the vehicle's structural frame rather than a surface trim piece.
The OEM cross bars mount to the roof gutter ledge using a clamp system. Our DualTrack crossbars bolt directly to the factory roof rail attachment points. Fully reversible to stock since no drilling or permanent modification is needed.

One owner in that same thread noted a practical concern with gutter-mounted bars: "As a side note, any Grenadier I have seen with racks or bars mounted to the rain gutter have warped them." This was disputed by another member who attributed it to improper dealer installation, but it's a data point worth understanding before you choose.
The DualTrack's factory attachment point design does come with one limitation: bar placement is constrained to the positions of the factory attachment points. You can't slide the bars fore and aft like you can with the gutter-mount OEM design. For most builds this is not a problem — the attachment points are spaced sensibly for the standard cargo configurations — but if you need a very specific placement for an oversized load, the OEM system offers more flexibility.
Load Ratings: Where They Diverge
The OEM crossbars carry a substantial static rating — 795 lb across two bars, according to owners who have verified this with their INEOS dealer documentation. Dynamic (driving) capacity is 198 lb. These numbers make the OEM bars the right call if you're hauling a very heavy load that you plan to install parked and leave stationary during transport — think a full expedition setup with multiple heavy cases.
The DualTrack™ 4-bar kit is rated at 400 lb static and 200 lb dynamic. The 2-bar kit rates 200 lb static and 100 lb dynamic. For rooftop tents (which are typically under 150 lb), recovery gear, lighting, Starlink, and standard cargo boxes, the 4-bar DualTrack comfortably covers what most Grenadier owners actually carry.
DVA's engineering team confirmed the rigidity in real-world conditions: "I have to stand on one [bar] with my full body weight (175 lbs) to see any deflection. During our Moab trip we had a case loaded to around 100 lbs up top, and I remember at least 3 hard rock hits on the side step. The impact sound never came from the roof."
Profile Height and Garage Clearance
The DualTrack™ adds approximately 1 inch of height to the Grenadier's roofline. That keeps you under a standard 7-foot garage door even with most accessories installed — including the DVA Starlink Mini mount, which sits flush to the L-Track surface. This is the detail that matters most for daily drivers who park in a home garage.
The OEM crossbars sit higher. One owner who runs both systems described the OEM setup as noticeably taller and noted noise at highway speed: "The DVA are very quiet. They are low profile... The OEM are very heavy duty and can be placed at any point on the rain gutters. The racks are higher. They can be noisy at speed if mounted forward of the roof bars."
If you're choosing a single system for year-round daily driving, the DualTrack's low-profile geometry is a meaningful quality-of-life advantage. Quiet, low, and garage-compatible.
The L-Track Ecosystem — DualTrack's Key Differentiator
Each DualTrack™ bar contains two full-length rows of industry-standard L-Track — the same channel system used throughout commercial cargo management. This is where the system earns its name: every accessory you add later snaps into precise positions along the bar without adapter plates or fixed mounting holes.
The DVA Starlink Mini roof mount clips directly to DualTrack L-Track. The DVA Recovery Board Carrier mounts to the same channel. Awning brackets, light mounts, cargo net anchors, O-rings — all position anywhere along the 58.5-inch bar length with no tools other than a wrench. For owners who iterate their build over time, the L-Track design means you're not locked into the configuration you start with.
The options for connecting loads with the L-Track is great... I leave the DVA on all the time.

The OEM crossbars use a proprietary channel system with end-cap accessory slots. They work with INEOS-certified accessories, but the ecosystem is narrower than the universal L-Track platform DVA uses. If you already own L-Track accessories — from a previous build or other vehicle — they'll likely work with DualTrack without modification.
Owner Installation and Fit Notes
Installation on both systems requires no drilling and is fully reversible. The DualTrack takes 45–60 minutes with basic hand tools, according to DVA's install guide. Owners on the forum confirm the process is straightforward.
One real-world fit note from the forum worth knowing before you buy: the DualTrack's ~1" profile is genuinely low. One owner flagged that cargo box mounting bolts needed trimming to avoid contact with the roof: "For me a thing to watch out for is just how low profile they are. I need to cut the mounting bolts for the cargo box down so they would not contact the roof. The outboard side clears, the inboard side did not and needed trimming."
This affects owners using longer-bolt mounting hardware on Pelican-style cases or RTT units with non-standard mount feet. DVA acknowledged this tradeoff — it's the direct consequence of going as low-profile as the design allows. Most standard RTT and cargo box hardware fits without modification; verify your specific case's inboard bolt length before ordering.
For Grenadiers with the high-power roof outlets installed, owners note this can limit usable bar positions on the DualTrack since the outlet housings occupy some rail real estate. The OEM gutter-mount design works around this since it doesn't share the roof rail attachment points.
Which System Is Right for Your Build?
Choose DualTrack™ if:
✓ You want a permanent, daily-use roof platform
✓ Garage clearance matters (7-ft door with accessories installed)
✓ You're building out with Starlink, lighting, recovery boards, or cargo systems
✓ You value quiet highway driving
✓ You want to expand accessories without replacing hardware
Choose OEM bars if:
✓ You need maximum static load capacity (795 lb)
✓ You want any-position placement along the full roof gutter
✓ You're mounting a side awning system that requires the gutter rail
✓ You already have OEM-compatible accessories you want to reuse
The forum consensus after 400+ Grenadier builds is clear: owners who prioritize daily use, garage clearance, and modular accessory integration choose the DualTrack. Owners hauling maximum static loads or needing gutter-specific accessory systems opt for OEM. The significant number of owners who run both — DualTrack permanently installed, OEM bars as a swap-on option for heavy-haul days — reflects the fact that these are complementary tools, not strict either/or choices.
DVA DualTrack™ System Overview
DVA's DualTrack™ system for the INEOS Grenadier is built from 6061-T6 extruded aluminum with a black powder coat finish. Each bar is 58.5 inches long, 3 inches wide, and weighs 5 lb. The dual L-Track channels run the full bar length, giving you independent front and rear positioning for every accessory you mount.
