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.


  • 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.
  • Net payload is 148 lb per vehicle manufacturer stated load carrying capacity.

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.

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.


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.

What about wind noise?

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!
