ARB RD170 Air Locker Differential with Pneumatic Locking System

The ARB RD170 Air Locker Differential delivers 100% traction on demand without sacrificing highway driving performance. Featuring ARB's improved two-piece design with forged gears and backed by an industry-leading five-year warranty, this differential locker gives you maximum control both on and off-road.

How It Works:

The Air Locker uses a pneumatically operated locking system activated by a 12-volt ARB air compressor. When engaged, it prevents the differential gears from rotating, locking both axle shafts together so they turn at the same speed. This ties both wheels directly to the ring gear rotation, ensuring maximum traction when you need it most. Simply flip a switch from the driver's seat to activate or deactivate the locker. When unlocked, the RD170 operates like a conventional open differential for normal highway driving.

Key Features:

• Improved two-piece design with forged gears for enhanced durability
• Pneumatic activation system controlled by 12V air compressor
• 100% traction on demand with switch-operated control
• Functions as standard open differential when disengaged
• Five-year manufacturer warranty coverage
• Enables slower, more controlled off-road driving to reduce vehicle damage and environmental impact

The ARB RD170 Air Locker transforms your 4x4's off-road capabilities while maintaining factory-like performance on paved roads, making it the ideal upgrade for serious off-road enthusiasts who refuse to compromise daily drivability.
