ARB RD143 Air Locker Differential with Pneumatic Locking System

The ARB RD143 Air Locker Differential delivers 100% traction on demand without sacrificing highway driving performance. This advanced locking differential features ARB's improved two-piece design with forged gears and is backed by an industry-leading five-year warranty.

How It Works:

The Air Locker uses a pneumatically operated locking mechanism activated by a 12-volt ARB air compressor. At the flip of a switch from the driver's seat, the system prevents the differential gears from rotating, locking both axle shafts together. This ties both wheels directly to the ring gear rotation, maintaining maximum traction. When unlocked, the unit functions as a standard open differential for normal highway driving.

Key Features:

• Improved two-piece construction with forged gears for enhanced durability
• Pneumatic activation system for instant engagement and disengagement
• 100% traction on demand when locked, open differential performance when unlocked
• Requires 12-volt ARB air compressor for operation (sold separately)
• Five-year manufacturer warranty
• Allows for slower, more controlled off-road driving to minimize vehicle damage and environmental impact

The ARB Air Locker provides superior off-road capability when you need it while maintaining the comfort and handling characteristics of an open differential for daily driving and highway use.
