Front Runner Slimline 3 3/4 Roof Rack Kit for Toyota 4Runner 6th Gen
Front Runner Slimline 3 3/4 Roof Rack Kit for Toyota 4Runner 6th Gen
The sixth generation 4Runner arrived with a lot of people waiting to build it, and the rack is usually the first thing on the list. This is the Dometic Front Runner Slimline 3, a three quarter length 2025 4Runner roof rack built specifically for the N500.
As a 6th gen 4Runner roof rack it is a flat platform: 60.3 inches long by 48.8 inches wide and sits 3.5 inches tall, 20% lower than the Slimline II, which cuts 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. The easy-release mounting system lets the rack come off without disturbing any roof seals. 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.
Why Three Quarter Length?
Most people shopping for a 4Runner roof rack assume full length is the goal. A three quarter rack stops short of the rear, and on a 4Runner that choice has real consequences rather than being a compromise.
Rear Hatch Clear
The 4Runner's rear glass and hatch stay unobstructed, which matters if you open them daily.
Less Weight Up High
At about 60 lbs this sits well below a full-length platform, on a vehicle that is tall to begin with.
Still Plenty of Platform
Sixty inches by nearly forty-nine takes a rooftop tent, or an awning plus boards and cargo.
If you want the whole roof covered, a full-length platform is the answer. If you want a working platform that leaves the back of the vehicle alone, this is it.
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. Slide the slats to where the gear needs them and carry on. On a 4Runner that gets built up gradually, that saves an afternoon every time.
Lower, Quieter, Cheaper to Run
Height is where this Front Runner roof rack separates itself. The Slimline 3 platform is 20% lower than the Slimline II, and on a 4Runner that is already tall, every bit back is worth having.
Less Drag
A lower platform presents less frontal area, which shows up directly in fuel consumption on a long highway run.
Less Wind Noise
The most common complaint about any platform rack. Lowering the profile is the most effective fix.
Better Clearance
A 4Runner is tall before you add anything, and taller again once lifted. Every inch counts in a garage.
Comes Off Without Unsealing the Roof
The easy-release mounting system uses an exclusive extrusion that lets you remove the rack without disturbing any roof seals. The mounting hardware stays in place and sealed while the rack lifts away.
That makes installation simpler and maintenance considerably easier, and it matters on a new vehicle where you would rather not be repeatedly unsealing a roof you just paid for. It also makes seasonal removal realistic rather than a job you avoid.
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 the Slimline 3 lets you set each without compromise.
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. Tent, awning, table, jack mount, boards, shovel, cans, lights, all on the same tray. For anyone shopping 2026 4Runner accessories, the rack is the foundation the rest of the roof hangs off.
Built for Weather and Abuse
- Heat-treated aluminium for the tray and slats, keeping weight down without giving up strength.
- 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
Will it fit my 4Runner?
This kit is built for the 6th Gen 4Runner (N500), the 2025 and newer generation. It includes the vehicle-specific MSTF003 three quarter mounting system, so it is not a universal fit. The 2010-2024 5th Gen needs a different rack entirely. Call us at 844-200-3979 with your year if you want it confirmed before ordering.
What does three quarter length mean in practice?
The platform covers most of the roof but stops short of the rear, leaving the back of the vehicle clear. You get 60.3 by 48.8 inches of usable tray, which takes a rooftop tent or an awning plus boards and cargo, while keeping weight down and the rear area unobstructed. If you want the entire roof covered, a full-length platform is the alternative.
Can I take the rack off without unsealing the roof?
Yes. The easy-release mounting system uses an exclusive extrusion that lets the rack come off without disturbing any roof seals. The mounting hardware stays in place and sealed while the rack itself lifts away, which makes both maintenance and seasonal removal far less of a job than it usually is.
Can I mount a rooftop tent on it?
The 60.3 by 48.8 inch platform takes most softshell and hardshell tents. Dometic does not publish a load rating for this kit, so check your tent's weight against Toyota's roof load limit for the 6th Gen before ordering. Call us at 844-200-3979 with the tent you are considering and we will help you work it out. Browse our rooftop tent collection here.
How does it compare to a Sherpa rack for the same truck?
Different approaches. The Slimline 3 is a platform tray with movable slats and T-slot channels, built around Front Runner's accessory ecosystem. The Sherpa Capitol is a full-length side plate and crossbar rack with published load ratings. If you already own Front Runner accessories, this is the natural choice. Call us at 844-200-3979 and we will talk it through.
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.
