The BASE Rack takes accessories and cargo loading to a whole new level of simplicity, speed, and personalization. The BASE Rack is fully-welded aluminum for lightweight strength that doesn't flex under load. It can therefore be mounted close to the vehicle roof for a slimline aesthetic and reduced drag. Its dovetail extrusion attachment system runs the full perimeter of the rack and along each internal beam providing endless mounting and attachment options. Adding, removing, and repositioning accessories and roof loads is quick and easy, and individual items may be installed or removed without disturbing the whole load. Unlike traditional roof rack channels, the BASE Rack dovetail system doesn't collect dust and debris. This kit includes a 72 in (L) x 51 in (W) BASE Rack and mount kit with wind deflector to suit the Toyota 4Runner. The longer rack allows for more storage space and ability to distribute the weight more evenly. ;
Features & Benefits
- Fully-welded from extruded aluminum with a cross beam design, the BASE Rack has no need for a supporting subframe and exerts no flex under load.
- Operation of manufacturer sunroof is not recommended while roof rack is installed.
- Maximum load per BASE Rack beam is 55 lb. Loads must be evenly distributed and adequately secured.
- Extruded aluminum beams feature rigid internal bracing. The cross beam design provides a loading platform for a more versatile range of cargo, particularly long, thin items such as timber.
- Finished in Integrit textured black powder-coat. This finish creates a durable, corrosion-resistant, scratch-resistant surface allowing you to easily clean off debris while the black color adds a sleek modern look to your vehicle.
- Removable end caps allow access to the channel for installing hidden electrical cables for roof lighting and solar.
- Unique dovetail mounting extrusion offers greater versatility, flexibility and speed in accessory placement and attachment. The dovetail design means less dirt entrapment and easy cleaning.
- The wind deflector mounted to the underside of the rack results in a quiet driving experience.
- Suited to a wagon the BASE Rack is 72 in (L) x 51 in (W) and approximately 44 lb. The added minimum height to the vehicle is 4 inches.

Product Highlights
Introducing the next phase in roof rack evolution… ARB BASE RACK
Ultra sleek, boasting a super low profile and lightweight design, the BASE Rack provides unmatched simplicity, flexibility and personalization in your roof rack set-up. Setting a new benchmark in strength and integration, the BASE Rack incorporates a revolutionary dovetail mounting system that makes attaching and removing loads and accessories easier, faster and more secure.
DESIGN STRENGTH MEETS STYLE
Fully-welded from extruded aluminum with a cross beam design, the BASE Rack has no requirement for a supporting subframe and exerts no flex under load. Each internal and perimeter beam is constructed from a single seamless extruded aluminum box piece with internal bracing for added strength.
The superior strength properties is what has allowed such close mounting to the vehicle’s roofline.

STRONG
The BASE Rack is manufactured from extruded aluminum beams. To further increase each beam’s rigidity, an additional aluminum bracing has been introduced which runs the entire length of each and every perimeter and internal cross-section.
Unique in design, the BASE Rack runs its beams horizontally instead of laterally, resulting in maximum strength and rigidity. Its strength omits the need of a subframe allowing the rack to sit lower for a sleeker finish.
-
Not only is it a strong rack, it’s a quiet one!
During the design process, the ARB’s team of engineers undertook extensive testing when it came to the concept of running the internal beams perpendicular to the vehicle. This has taken away concern of increased wind noise, as it was found that not only is the BASE Rack nice and strong – it’s also quiet!
The wind noise testing revealed that the majority of cabin noise from roof racks comes from only the very front perimeter cross-section, and this was very easily overcome with a formed wind-deflector which mounts on the underside of the rack on wagons with blade mounts.
The result? A very comfortable and quiet roof rack experience!
LOW-PROFILE
A one-piece, fully welded platform rack fitted to a range of low-profile blade mounts, the BASE Rack provides improved access into low clearance areas, all the while looking sleek on the roof of your vehicle.
UNIQUE DOVETAIL DESIGN
By incorporating a dovetail extrusion around both the full perimeter and along each edge of the internal beams, the BASE Rack provides endless mounting and attachment options.
Side mounting also frees up more uninterrupted cargo space along the top of each internal and external beam.
THE BASE RACK IS BUILT TO CARRY GEAR
…and a whole lot of it
CABLES BE GONE
Nothing ruins the sleek look like visible electrical cable. Yet another advantage of the aluminum extruded beam design is that electrical cabling can be fed in either through the removable corner caps or via the capped access points available on the inner surface of the side perimeter beams. Additional holes can easily be introduced along the perimeter beams wherever you are mounting your work or driving lights.
THE RANGE
The BASE Rack is available in a number of sizes to complement the vast range of 4×4’s on the market.
Sold standard as a low-profile platform rack, then it can easily transform into a touring or trade rack by simply installing the rail system that best suits your needs!
-
As each size reduces, the BASE Rack drops an internal beam.

GUARD RAIL SYSTEMS
The BASE Rack rail system is available in full, quarter three-quarter and trade configurations,
Attaching quickly and easily to the dovetail extrusion around the rack’s perimeter, the range of optional rails mean you can have a full guard rail system on or off in just a few minutes!
-
Designed for the tourer. The rails running around the perimeter of the rack act as a load block, helping to prevent larger items such as swags and tents from shifting when loading and unloading, as well as during transit.
-
A cross between full and trade rails, 3/4 rails, along with an optional roller kit, assist with easy rear loading of large and awkward items while still providing load security at the front of the rack. Also designed for rear folding rooftop tents, subject to tent width.
-
Perfect for campers, this style of rail is great for rooftop tents while still providing ample storage and load security at the front of the rack.
-
The trade option; great for loading long items such as timber and ladders with an optional roller kit to help glide long or awkward items onto the rack. The side rails prevent items from slipping or rolling of the rack during loading and allow you to fill the rack right up to the edge.
MAKE IT YOUR OWN
The BASE Rack takes accessories and cargo loading to a whole new level of simplicity, speed, and personalization thanks to its revolutionary side-mounting dovetail system. With a choice of sizes, accessories, and attachments, you can truly Make It Your Own.
Adding, removing, and repositioning accessories and roof loads is quick and simple with the BASE Rack’s dovetail system, making it easier to install and remove individual items without disturbing any other cargo or lashing points.
