Front Runner Slimline 3 Roof Rack Kit for Ineos Grenadier
Front Runner Slimline 3 Roof Rack Kit for Ineos Grenadier
If You Have Safari Windows, Read This First
With this rack installed, the Grenadier's safari windows cannot fully open. Dometic states this plainly and so do we. If those windows are something you use regularly, factor it in before ordering rather than after installation. Call us at 844-200-3979 if you want to talk it through.
The Grenadier was built for people who wanted a proper expedition vehicle back, and almost nothing in the aftermarket has caught up yet. The Dometic Front Runner Slimline 3 is a purpose-built Ineos Grenadier roof rack, not a universal platform bolted to a generic mount.
This Grenadier roof rack is a 108 inch flat platform, 61.4 inches wide, and it is height adjustable: 2.4 inches in the low position or 3.5 inches in the high. Either way it is 20% lower than the Slimline II, cutting drag, wind noise and fuel consumption. Slats move individually without dismantling the rack, dual T-slot channels take accessories at multiple pitches, and all four corners carry integrated tie-down points. Wiring for lights routes through concealed channels in the side profiles. Heat-treated aluminium and high-strength 3CR12 stainless steel, black powder coated, with stainless fasteners. Limited Lifetime Warranty.
Two Mounting Heights, One Rack
This is the feature that separates the Grenadier kit from the rest of the Slimline 3 range. The mounting system is height adjustable, so you choose where the platform sits.
| Low Position | High Position | |
|---|---|---|
| Platform Height | 2.4" (60mm) | 3.5" (90mm) |
| Best For | Lowest possible profile, garage and overhead clearance, least drag | Extra clearance under the tray for mounting hardware and accessories |
The low position gives you the cleanest look and the least wind resistance. The high position buys you clearance underneath, which matters if you are routing accessory hardware or want air space between the tray and the roof. You decide at install, and you can change it later.
Move Slats Without Dismantling Anything
On the Slimline 3 you can add, remove, or shift individual slats without taking the rack apart. Fitting a new accessory no longer means pulling the tray down and rebuilding it around the mount. Across a 108 inch platform where you may be arranging a tent, an awning, boards and cargo together, that flexibility saves an afternoon every time the build changes.
What Nine Feet of Platform Gets You
At 108 inches long and 61.4 inches wide, this Ineos Grenadier roof rack is one of the largest platforms Front Runner builds, which suits the vehicle it is made for.
Tent Plus Everything
A rooftop tent takes one section while the rest stays free for an awning, boards, cans and a shovel.
Expedition Loads
Long-haul kit for a trip measured in weeks rather than a weekend, laid out properly rather than stacked.
Full Width
61.4 inches across is wider than most platform racks, which changes what you can lay side by side.
Lower, Quieter, Cheaper to Run
The Slimline 3 tray is 20% lower than the Slimline II in either mounting position, and across 108 inches of length that reduction adds up.
Less Drag
A lower platform presents less frontal area, which shows up in fuel consumption on a vehicle that is not aerodynamic to begin with.
Less Wind Noise
The most common complaint about any platform rack, and the low mounting position is the most effective fix.
Better Clearance
A Grenadier is already tall. Choosing the low position buys back over an inch against the high.
Dual T-Slots and Staggered Insertion
Each slat carries dual T-slot channels with multiple staggered insertion points along its length, and slats can be set to different mounting pitches.
That means you can insert hardware at several points rather than threading it from one end, and you can change spacing to suit what you are mounting. A rooftop tent wants different pitch to a pair of recovery boards, and across a platform this size you will want both on the same rack.
Details That Show Up in Daily Use
Integrated Tie-Down Points
All four corners have built-in tie-down points compatible with Stratchits, Stratchit shorties, and other lightweight securing straps. No add-on brackets needed for the strapping most people do most often.
Concealed Wire Routing
Dedicated channels within the side profiles let you route wiring for lights and other electrical accessories out of sight. Corner sections include built-in pass-throughs and breakout tabs, so wires enter and exit cleanly rather than being cable-tied along the outside of the rack.
Full Accessory Compatibility
Every Front Runner top-mount accessory works with the Slimline 3. On a platform this size that is the point, and it matters more on a Grenadier than most vehicles, since dedicated Ineos Grenadier accessories are still thin on the ground. The Front Runner ecosystem gives you a catalogue to build from.
Built for Weather and Abuse
- Heat-treated aluminium for the tray and slats, keeping weight sensible across a nine foot platform.
- High-strength 3CR12 stainless steel in the structural components, chosen for corrosion resistance in wet and salty environments.
- Weather-resistant black powder-coated finish over the top.
- Stainless steel fasteners as standard, not an upgrade.

Frequently Asked Questions
What happens to my safari windows?
With this rack installed, the safari windows cannot fully open. Dometic states this directly, and it is worth knowing before you commit rather than after the rack is on. If the safari windows are something you use regularly, call us at 844-200-3979 and we will talk through the options for your build.
Which mounting height should I choose?
The low position at 2.4 inches gives the cleanest profile, the least wind noise, and the best overhead clearance. The high position at 3.5 inches buys you clearance underneath the tray, which helps if you are routing accessory hardware or want air space above the roof. Most people choose low unless they have a specific reason not to. You decide at install and can change it later.
Can I mount a rooftop tent on it?
Yes, and at 108 by 61.4 inches a tent uses only part of the platform. The rest stays free for an awning, boards and cargo. Dometic does not publish a load rating for this kit, so check your tent's weight against the Grenadier's roof load limit before ordering. Call us at 844-200-3979 with the tent you are considering. Browse rooftop tents here.
What else can I mount on it?
Every Front Runner top-mount accessory, which on a Grenadier matters more than it would on a Tacoma. Dedicated Grenadier accessories are still limited, so getting onto a platform with a mature accessory catalogue means tables, jack mounts, shovel brackets, can holders, light mounts and awnings are all available immediately rather than waiting for the aftermarket to catch up.
Can I run wiring for lights through it?
Yes, and cleanly. Dedicated channels inside the side profiles carry wiring for lights and other electrical accessories out of sight, and the corner sections have built-in pass-throughs and breakout tabs so wires enter and exit where you need them. No cable ties along the outside of the rack.
Will my existing Front Runner accessories fit?
The Slimline 3 is compatible with all top-mount accessories in the Front Runner range. If you are moving over from a Slimline II and have accessories that rely on the older slat spacing, it is worth checking those specifically before you order. Call us at 844-200-3979 with what you are running and we will confirm.
