ARB RD157 Air Locker Locking Differential for 07-18 Jeep Wrangler JK Rubicon with 35 Spline Dana 44

Quadratec Part #: 16100.2014
ARB Part #: RD157
Locking differentials have been available for years, but were always a compromise: performing well either off the road or on the road - but not on both. The ARB Air Locker provides normal differential action on the street - maintaining safe, predictable handling. An ARB Air Locker differential will drive out of the most difficult situations.

Here's how it works: The ARB Air Locker is an air-operated, driver-controlled differential locker activated by pushing a dash-mounted button. When engaged, compressed air, delivered by the ARB (12-volt) on-board air compressor is passed via a 12-volt solenoid down an air line into the differential housing. Air travels into the differential center via a specially designed seal housing which seals against an extended bearing with air fitting. Through air galleys, the compressed air enters the piston chamber & actuates the piston and clutch gear, moving the gear into the locked position. The clutch gear now locks the side gear to the differential housing, instantly stopping differential action. Differential is now locked, and both axles will deliver traction. To disengage the differential, push the dash mounted switch again. It releases the compressed air via the solenoid and the piston springs return to the original position. Differential is then open again, allowing full, standard differential action. ARB Air Locker only takes a split second to engage, making it the only real driver-controlled differential locking system on the planet.
