ARB RD117 Air Locking Differential for 4x4 Off-Road Trucks & Jeeps - Heavy Duty Performance Upgrade for Rock Crawling & Trail Riding

Product Description

RD1117 AIR OPERATED LOCKING DIFFERENTIAL by ARB The ARB Air Locker is a replacement differential carrier that can either operate as a conventional differential, or lock both rear (or front) axle shafts together allowing maximum drive torque to be transmitted to both wheels. The locking function is controlled from the vehicle dashboard by the driver. Front axle Air Lockers can be locked when traversing slippery surfaces giving maximum traction, or unlocked on high traction surfaces to retain full control of the steering. As a safety feature, the front differential cannot be locked unless the rear differential has first been locked. The ARB Dana 44 air locker RD117 for your 30 spline axle for 3.73 & down gear ratios, can instantly lock differentials and allow you to tackle the toughest off-road terrain. The world's best traction aid, ARB Air Lockers keep you moving in all conditions. Air Lockers from ARB are currently available in over 100 configurations to suit a wide range of off-road and 4x4 vehicles from around the world. Because the Dana 44 ARB RD117 air locker is only engaged when needed, it can be installed in BOTH the front and rear axles, with separate switches independently controlling the RD117 air locker from within the off-road truck or vehicle. Since the Air Locker is pneumatically actuated, an onboard compressor, or other air supply, is REQUIRED. ARB recommend ARB Air Compressors (CKMTA12, CKMA12 or CKSA12).The air compressor is started with the air compressor switch, and a pressure switch maintains the air pressure in the reservoir between 585kPa [85psi] and 690kPa [100psi]. When the Air Locker switch is operated, the relevant pneumatic solenoid valve opens, allowing compressed air down the line to the differential. When the Air Locker switch is turned off, the solenoid valve closes the port from the compressor, and opens the exhaust port allowing the air in the differential to be exhausted. The return springs force the clutch gear back to its original position, disengaging the clutch gear from the splined side gear, freeing the internal gears so that they can once again provide the same normal differential action as the original open factory differential. RD117 AIR OPERATED LOCKING DIFFERENTIAL by ARB Air compressor is not included, but needed. ARB recommend (CKMTA12, CKMA12, CKSA12).
