ARB BASE Rack Modular Roof Rack System

The ARB BASE Rack is a fully modular, low-profile roof rack platform engineered for overlanders, 4x4 adventurers, and working professionals who demand flexibility without compromise. BASE — Build, Attach, Set, Explore — defines the system's core philosophy: a fully configurable roof platform that adapts to any mission, any load, and any lifestyle. Backed by ARB's heritage as one of the original pioneers of the roof rack, dating back to the company's founding in 1975, the BASE Rack represents a ground-up reinvention of what a modular roof platform can be.

Proprietary Dovetail Mounting System:

At the heart of the BASE Rack is ARB's full-perimeter dovetail extrusion system — a significant departure from conventional T-slot designs. The dovetail profile runs the full perimeter of the rack and along each internal beam, delivering virtually endless mounting and attachment options. Accessories mount to the sides of the rack rather than the top surface, providing an uninterrupted cargo area free of protruding tie-down points. Unlike traditional roof rack channels, the dovetail system does not collect dust and debris, keeping your setup clean and functional mile after mile.

Fully Welded Aluminum Construction:

The BASE Rack is built from fully welded extruded aluminum with a vertical cross-beam structure that eliminates the need for additional sub-frame supports. This construction delivers exceptional strength-to-weight performance while allowing the rack to mount close to the vehicle roof for a sleek, low-profile aesthetic and reduced aerodynamic drag. The result is zero-flex performance under load without unnecessary bulk.

Configurable Rail System:

Sold as a low-profile platform rack, the BASE Rack is easily transformed by installing the rail configuration that best suits your needs. Available layouts include full rail, three-quarter rail, trade rail, and quarter rail configurations — meaning the same rack foundation can serve as a weekend adventure platform, a work trade rack, or a minimal flat carrier. Switching between configurations requires no specialized tools or complicated hardware.

Purpose-Built Accessory Ecosystem:

ARB has developed a comprehensive range of BASE Rack-specific accessories that leverage the dovetail attachment system. Adding, removing, and repositioning individual items is quick and easy without disturbing the rest of your load. Available accessories include Hi-Lift jack brackets, recovery board mounts, jerry can holders, spare tire tie-downs, and LED light bar mounts — all designed to integrate seamlessly into the system.
