ARB RD197 Air Locker Differential for Dana - 60 Front

The ARB RD197 Air Locker is a pneumatically-operated differential locking system designed to deliver 100% traction on demand without compromising on-highway performance. Featuring ARB's improved two-piece design with forged gears and backed by an industry-leading five-year warranty, this differential locker provides the ultimate combination of strength, reliability, and versatility for serious off-road enthusiasts.

How It Works:

The ARB Air Locker uses a 12-volt air compressor to activate a solid locking mechanism inside the differential housing. When engaged via a simple dash-mounted switch, the Air Locker prevents the differential gears from rotating, locking both axle shafts directly to the ring gear. This ensures both wheels receive equal power and maintain maximum traction, even when one wheel loses contact with the ground. When unlocked, the differential operates like a conventional open differential for normal street driving.

Key Features:

• On-demand activation from the driver's seat with simple switch control
• Two-piece forged gear design for enhanced strength and durability
• Pneumatic locking system provides instant engagement and disengagement
• Functions as an open differential when unlocked for normal driving
• 100% traction when locked—both wheels driven equally regardless of surface conditions
• Allows slower, more controlled driving on challenging terrain, reducing environmental impact
• Industry-leading five-year warranty coverage

Benefits:

Unlike always-on locking differentials or limited-slip designs, the ARB Air Locker gives you complete control over when traction is needed. This versatility makes it ideal for vehicles that see both daily street use and serious off-road conditions. The ability to drive in a more controlled manner with both wheels engaged also minimizes wheel spin, vehicle damage, and trail degradation.
