To complete the range of Air Locker locking differentials available for Nissan GU Patrols, ARB 4x4 Accessories has just released an exceptionally strong rear Air Locker for cab chassis leaf sprung models that use a H260 with 34 spline full floating axles. Built to suit the vehicle’s formidable size and power, this new Air Locker application (RD144) gives GU Patrol owners the opportunity to experience the ultimate in traction on demand. Providing outright improvements to a vehicle’s off road capabilities, an Air Locker also allows a 4WD to be driven in a more controlled manner, thus reducing the likelihood of vehicle damage and environmental impact.

The attraction of an ARB Air Locker lies in the fact that it is a replacement differential that gives the best of both worlds – a normal open differential for on road use, and a positively locked differential for challenging off road situations. ARB Air Lockers utilise a 12-volt compressor that delivers high-pressure air to the differential centre, thereby engaging the locking mechanism. With both wheels tied directly to the rotation of the crown wheel, the vehicle maintains maximum traction when the Air Locker is activated.

The RD144 features the Air Locker’s patented ‘timed’ locking mechanism for maximum strength and super long life, and a new, steel reinforced elastomer bonded annular seal designed to handle extreme temperatures. The Air Locker also incorporates structural components manufactured from aerospace grades of high alloy steels, and retains the advantage if being activated by a dash mounted switch.

ARB Air Locker’s patented design has proven ultra reliable even under the most arduous conditions. A massive range of vehicle applications, coupled with an impressive track record for durability and performance, has significantly contributed to the Air Locker’s worldwide popularity, with the product used in over 100 countries by a very diverse customer base.

Designed for Air Locker activation, ARB’s 12 volt on-board air compressor (CKMA12) further improves a 4WD’s off road capabilities. Constructed entirely of light weight, high strength engineering grade materials, including military and aerospace standard components, the compressor combines a compact design with the highest air flow in its class to make it the leading air compressor on the market. Affordable and engineered to suit any off road adventure, its versatility allows for applications such as ARB Air Locker activation, tyre inflation and the inflation of accessories like air mattresses and recreational items.

Tip:

Engine Bay Protection<br> Placing a tarp across the front of the 4x4 minimizes water entering the engine bay by creating a bow wave, provided forward momentum is maintained. The result is less water for the radiator fan to spray over the ignition system, less chance of water entering the air intake and less likely for the fan to propel its way up to and through the radiator. Diesel 4x4 's are usually better for water crossings as you do not have the ignition system to worry about. Water in the ignition system usually results in a stalled engine and not actual engine damage, though this is of little comfort when you find yourself stuck in the middle of a crossing. Depending on the water depth, its advisable to climb out of your window rather than open the door and flood your carpets. To minimize stalling from a wet ignition, it's a good idea to spray all the ignition system with water repellent beforehand.
