ARB RD171 Air Locker Differential for Maximum Traction Control

The ARB RD171 Air Locker Differential delivers 100% traction on demand without compromising highway driving performance. This pneumatically-activated locking differential gives you complete control over your vehicle's traction with the simple flip of a switch from the driver's seat.

Key Features:

• Improved two-piece design with forged gears for enhanced durability
• Pneumatic locking system prevents differential gears from rotating when engaged
• 12-volt ARB Air Compressor activates and deactivates the locking mechanism
• Locks both axle shafts directly to ring gear rotation for maximum traction
• Functions as conventional open differential when unlocked
• Industry-leading five-year warranty coverage
• Enables slower, more controlled driving to reduce environmental impact

How It Works:

When activated, the Air Locker's pneumatic system prevents the differential gears from rotating, which stops the axle shafts from turning independently. This ties both wheels directly to the ring gear's rotation, maintaining maximum traction at all times. When disengaged, the differential operates normally, providing smooth on-road performance.

The ARB RD171 Air Locker significantly improves off-road capability while offering environmental benefits through more controlled vehicle operation. Perfect for serious 4x4 enthusiasts who need reliable traction in challenging terrain without sacrificing daily drivability.
