The Next Generation Of 4X4 Accessories
LINX is a unique modern controller that declutters the dashboard and centralises the command of vehicle accessories by replacing classic switches, gauges and monitors with one sleek and smart driver interface. Built on an expandable platform, LINX will continue to evolve your on and off-road driving experience both now and into the future.
Experience Total Control
Fitting out a modern 4X4 with a range of accessories such as driving lights, air lockers, dual batteries and air compressors can quickly lead to a dash full of out of place, hard to reach switches and a myriad of gauges and monitors either stuck to the windscreen or drilled into the dashboard - not to mention all the associated fuses and wiring.
LINX offers a single point of control via its user-friendly, Bluetooth enabled, mobile touch screen display. The LINX mobile display mounts conveniently and unobtrusively within reach of the driver while the main control hub lies neatly out of sight under the dash or seat; taking care of all accessory wiring.
LINX comes with six pre-installed modules: Front and Rear Traction, Compressor Control, Accessory Switchboard, Battery Monitor, Speedometer and Air Suspension Control. See below for more details.
General Settings
Beyond its expansive range of modules, LINX presents a truly adaptable platform with module level settings, as well as, many additional general settings. Within the general settings of LINX users can customize the colour theme to match any interior dash theme; apply night mode for automated dimming which is activated by the vehicle’s headlights; and set the preferred unit measurements for air pressure, speed and temperature. As an expandable platform, simply connecting the screen to a WiFi point allows you to upgrade your LINX with any new updates at the press of a button.Functions
- Set theme colour to match your vehicle’s dash
- Engage night mode which engages when your headlights are activated
- Set all measurements to your preferred units
- Software upgradeable via WiFi connection

ARB Diff Cover (DA8926)
- High tensile solid nodular iron structure (tougher and harder than solid carbon steel) protects the differential and ring & pinion set from the obstacle impact hazards of competition rock crawling, or extreme off road trails.
- Computer optimized cross brace design adds more than 1300 Nm/deg (960ft-lb) of torsional rigidity to the entire axle assembly. This increased flexural strength in the housing helps keep the ring & pinion gears meshing on the flat faces of the teeth, which greatly increases ring & pinion life and overall maximum load strength.
- Carrier bearing life is prolonged, especially on high output vehicles, by the improved support given to the bearing alignment.
- Low-profile shape of the outside surface helps maximise the running gear clearance around the cover.
- Maximized approach/ departure angled exterior surfaces help to minimise rock/ obstacle hang-ups.
- High tensile cap screws (supplied with the kit) are recessed into the cover to protect them from contact with obstacles which might damage or loosen them.
- Cover is powder coated, CNC machined, then clear coated for a durable, professional, long lasting finish; hardware is zinc plated.
- Low profile drain plug design resists damage from obstacles.
- Combination of the high filler point and dipstick allows the oil to be checked for water contamination without having to drain the oil.
- Magnet location in the end of the dipstick allows the oil to be checked for tell-tale signs of internal damage.
- Top quality, high power neodymium magnets are used in both the drain plug and the dipstick to collect metallic wear particles as the vehicle moves.
