INEOS Grenadier Roof Rails — DualTrack-T MAX
Mount everything. Drill nothing. Dual-row L-Track and 25 mm T-Slot in one 1" rail — awning, tent, Starlink, recovery gear, mounted anywhere along the bar.
What will you mount?
Dual mounting standards mean your existing L-Track and T-slot accessories both fit — no adapters.
Build your kit
Every kit ships with rails and factory-point hardware. Installation videos are available online.
Complete your build
Everything here mounts straight to the rails, and ships in the same order.
Your Grenadier still fits in the garage.
The most repeated line in five years of owner reviews isn't load rating or L-Track. It's that the truck still goes under the door. DualTrack-T MAX adds 1 inch over the factory roofline — approximately 78.5 inches overall on a stock Grenadier, roughly five and a half inches under a standard 7-foot door. A lift or larger tyres change that.
- “Still allows my Grenadier to fit in a standard garage.”Eric M
- “Needed a very low profile to fit in my garage — these work perfectly.”Peter Baldock
- “Perfect for my super low garage door. It added only about 3/4 inch.”Michael Aylward
The questions everyone asks
Will it make wind noise?
The rails sit about 1 inch above the roofline, within the already disturbed airflow along the Grenadier’s roof. That low position helps limit additional wind noise; owners commonly report no noticeable increase at highway speed. Read the wind-noise engineering guide →
Do I have to drill my roof?
No. DualTrack bolts to the Grenadier's factory mounting points with supplied hardware. Zero drilling, zero permanent modification, fully reversible to stock in under an hour.
How much can it hold?
2 rails — 150 lb dynamic / 300 lb static. 4 rails — 300 lb dynamic / 600 lb static. 6 rails — 330 lb dynamic / 900 lb static. Dynamic applies while the vehicle is moving; static applies when parked. At six rails the dynamic figure is set by the Grenadier's OEM published roof maximum of 330 lb, not by the rails.
Does it replace my OEM roof bars?
No — your factory roof bars stay on. DualTrack-T MAX mounts to the factory mounting points and works alongside the OEM longitudinal rails.
Will my existing accessories fit?
Standard L-Track fittings and 25 mm T-Slot hardware mount directly to the rail — no adapter plates.
Can I add rails later?
Yes. Two, four and six rails all work on the Wagon, the hardware is identical, and adding a pair later needs no re-shimming of what is already fitted — provided no other aftermarket hardware occupies the roof mounting points.
How do returns and shipping work?

On real Grenadiers
The DualTrack Low-Profile Roof Crossbar System is a perfect addition to my Field Master Grenadier. It is strong and sturdy. It was very easy to install and really blends in nicely with the design of the truck. The price point makes it a great value as a base for the other available DVA products.
It’s a nice surprise to install something that’s engineered well with clear instructions and actually looks and functions as advertised. Racks are easy to install , highly functional and still allows my Grenadier to fit in a standard garage. Much bettef than the OEM that fasten to the rain gutter on the truck.
Great products, roof crossbar fit like a glove! Outstanding Customer Service!!
Will buy more products from them.

I loved how low profile it is and how strong it’s, and I really like the after sale customer service as they are amazing and I highly recommend them! As I’ve got my first package with damage as they were so fast with their service as they sent me all four rails again new in a perfect condition!! I would suggest their product and all the hard team effort they are doing to make every order unique and above expectations! I’m a really happy customer with their product and the after sale service.
Thank you and best regards,
Great product and great support from the team at DVA.
I needed a very low profile to fit in my garage and these work perfectly.
The bars are well done, fit perfectly and look great. I had a few questions along the install and the customer service was great - Thanks Derek!
Good product, low noise as advertised.
Great product! Looking forward to more new products.
Solid! Super well-made, easy to install, fair price.
Still fits in the garage under the 7 ft door as advertised. Easy install and great communication.
Super easy to assemble and attach. Less wind noise than the big heavy duty bats.
Perfectly designed easy to install
Nicely manufactured and easy to fit.
Slight contact with vehicle roof rails. Also needed to buy 4x counter sunk bolts as they were short supplied
Otherwise all good!
I did the 4 rail system and it works perfectly for my super low garage door. It added only about 3/4 inch in height (that's an estimate). Plenty of options/opportunities to connect/tiedown/haul on the roof now.
Super easy install, took maybe 40 minutes? The first rail took the longest, then it was super simple from there. I did use removeable threadlock as recommended
Great quality, fits as advertised plus 6 day delivery from USA to AU.
pretty weak in regards to overall build. the bars flexed under load, tapping against my roof every bump I went over
Excellent low-profile roof bars that use the same L-track mounting hardware that the Ineos Grenadier utility belt leverages. Also ideally built for mounting LED Scene lights.
Solid product. Fits like a glove. Very happy with the roof rails.
The product is very well sorted with the exception of the length of the slots for the bolts that go through the crossbars into the upright brackets (which are intended to compensate for the varying width of the Grenadier roof). When I installed the 4-bar setup, I noticed that one of the bars (the furthest rearward) bowed upwards when the bolts were snugged. This is because the slots were not far enough inward, which resulted in the uprights being tilted slightly downward (which resulted in the cross bar being stressed when snugged). For the more forward bar, the opposite...when tightened, the bar bowed downward. To address the bowing, I elongated the slots. I believe if the slots were longer in each direction by 1/8 inch, the bars would remain flat.
Fantastic quality
Fast delivery
Hello The low profile roof crossbars look good and was a easy install Thank you!
Serious quality. Everything looks great and is solid. Thanks for not cheesing out with cheap screws and bolts.
Great quality and easy installation.
Please respond to my email about the missing support brackets. The racks are great and I’d like to provide a positive review but can’t until I receive the full set.
Unbelievably easy to install
So far so good. Install was easy enough at 34 deg.
Haven’t put any thing up there yet.
So impressed with the low profile crossbars, look even better in real life! Super fast shipping from the US to Australia. Finishes off the roof perfectly and would highly recommend.
