ARB RD205 Air Locker Differential - Pneumatic Locking Differential

The ARB RD205 Air Locker is a pneumatically operated locking differential that delivers 100% traction on demand without compromising highway driving performance. This innovative differential system employs a 12-volt ARB air compressor to activate and deactivate a solid locking mechanism inside the differential, giving you complete control over traction at the 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
• Locks both axle shafts directly to ring gear rotation for maximum traction
• Functions as conventional open differential when unlocked
• 12-volt air compressor activation system included
• Industry-leading five-year warranty coverage
• Allows slower, more controlled driving to reduce vehicle damage and environmental impact

When activated, the Air Locker prevents the axle shafts from turning independently of each other, tying both wheels directly to the ring gear rotation for maximum possible traction in challenging off-road conditions. When unlocked, the differential operates exactly like a standard open differential for normal highway driving. This on-demand functionality makes the RD205 ideal for 4x4 vehicles that need serious off-road capability without sacrificing daily drivability.
