Front Runner Slimline II 6th Gen Toyota 4Runner Roof Rack (2025 - Current)
The 6th gen 4Runner deserves a roof rack that matches its capability, and the Front Runner 4Runner Slimline II Roof Rack delivers exactly that. This is the full-size 2166mm/85.3" Slimline II kit engineered specifically for the 2025+ Toyota 4Runner. It is a no-drill, bolt-on platform built to carry roof top tents, awnings, traction boards, and every piece of overland gear you can throw at it. If you have been waiting for a rack that is vehicle-specific, factory-clean, and trail-tested, this is it.
We have been bolting Front Runner racks onto rigs for years, and this 6th Gen 4Runner Slimline II Roof Rack continues the same formula that put them on the world's most serious overland builds. Aluminum tray. Steel-reinforced foot rails. T-slot mounting throughout. Backed by a 5-year warranty.
Built for the 6th Gen Toyota 4Runner
Most "universal" roof racks force you to compromise on fit, height, or aesthetics. This Front Runner roof rack kit is not one of them. The vehicle-specific Foot Rails (FATF009) bolt into the existing factory mounting points on your 6th gen 4Runner. No drilling. No cutting. No permanent modification. Pull it off years from now and your roofline goes back to stock.
The full-size 2166mm length covers nearly the entire roof span, giving you the maximum usable real estate on top of the truck. That matters when you are trying to fit a roof top tent and an awning on the same rack, or when you want every inch of cargo space for an extended expedition.

The Slimline II Tray: Heart of the System
The Slimline II Tray is what makes this rack genuinely modular. Front Runner uses a flat, low-profile design with continuous T-slots running along the top, bottom, and edge profiles of every slat. That means accessory mounting is not restricted to a few drilled holes. You can mount, slide, and reposition gear anywhere along the tray.
Why T6 Aluminium and Steel Matters
Black epoxy powder-coated T6 aluminium hits the sweet spot between strength and weight. T6 aluminium is heat-treated for higher tensile strength, and the powder coat finish bonds at a molecular level for genuine corrosion resistance. This is not paint that flakes off the first time you load gear onto it. The Slimline II roof rack is built to outlast the truck.
Pair the aluminum tray with high-strength steel foot rails and you get a rack that is rigid where it needs to be (where it bolts to the vehicle) and lightweight where it does not (the tray itself). Total installed weight lands at around 41kg.
T-Slot Mounting in Plain English
The T-slots accept standard 8mm bolts on top and bottom. Front Runner builds an enormous accessory ecosystem around this slot pattern: jerry can holders, awning brackets, MAXTRAX mounts, shovel mounts, water tank mounts, light brackets, and more. If you are running a Front Runner accessory, it bolts directly to this tray. No adapters, no drilling.
Vehicle-Specific Foot Rails with Under-Rack Storage
The FATF009 Foot Rails are the secret sauce. They are cut and bent to match the 6th Gen 4Runner's roofline exactly, so the tray sits at the correct height and angle, not perched awkwardly above the cab. The rails also include a pass-through opening that lets you mount a Front Runner Dometic under-rack table beneath the tray.
That opening accepts one smaller prep table or one larger camp-size table. So you have a workstation tucked underneath the Front Runner roof rack that drops down when camp is set, and tucks back away when you are rolling. It is the kind of detail that tells you Front Runner's engineers actually use this gear in the field.
Wind Deflector Included
Roof racks make noise. That is physics. The included Wind Deflector slices through the airflow before it hits the front edge of the tray, killing the whistle and reducing the buffeting you would otherwise hear at highway speeds. It also drops your aerodynamic drag, which means fewer MPGs lost compared to a bare bar setup.

Who This 4Runner Roof Rack Is For
This is a serious 4Runner overland rack for serious builds. If you are loading up for week-long expeditions, mounting a hardshell or softshell roof top tent, running a 270 degree awning, or hauling traction boards and recovery gear across desert and mountain terrain, this is the platform you build on.
It is also right at home on a daily-driver 4Runner that needs flexible cargo capacity. The flat Slimline II tray works just as well for a kayak, ski rack, or roof box as it does for a fully loaded overland kit.

Frequently Asked Questions
Will the Front Runner Slimline II Roof Rack fit my 5th Gen 4Runner?
No. This Toyota 4Runner roof rack is engineered specifically for the 6th Gen platform (2025-Current). The Foot Rails are cut for that vehicle's mounting points and roof profile. Front Runner offers separate Slimline II kits for earlier 4Runner generations.
Does installing this 4Runner roof rack require drilling?
No. The kit installs using your 4Runner's existing factory mounting points. It is a bolt-on system, fully reversible, and does not compromise the roof or factory body integrity.
Can I mount a roof top tent on this Slimline II rack?
Yes. The Slimline II tray's T-slot system supports both hardshell and softshell rooftop tents. Use 8mm hardware to secure mounting brackets through the slats. Confirm your specific tent's mounting hardware matches the 8mm slot pattern before installing.
What accessories work with the Front Runner roof rack kit?
The full Front Runner accessory range bolts directly to the Slimline II tray: jerry can holders, MAXTRAX mounts, awning brackets (270 degree and standard), shovel mounts, water tanks, light brackets, table systems, and more. The 8mm T-slot pattern is the universal mounting standard across the entire line.
How tall does this make my 4Runner?
Add the tray height (50mm/2") to the foot rail height for the total stack above the highest point of your roof. Most 6th Gen 4Runner owners see roughly 2.5 to 3 inches added to total vehicle height once installed. It is worth measuring your garage clearance before mounting.
