ARB RD201 Air Locker Locking Differential

The ARB RD201 Air Locker is a pneumatically-operated locking differential designed to provide maximum traction in challenging off-road conditions. When activated, the Air Locker mechanically locks both axle shafts together, forcing both wheels to turn at the same speed regardless of available traction. This ensures power is distributed equally to both wheels, preventing wheel spin and keeping you moving through mud, sand, rocks, and other difficult terrain.

Key Features:

• 100% lockable differential for maximum traction on demand
• Pneumatic activation system for reliable engagement and disengagement
• Seamless operation - engages and disengages at any speed
• Durable forged steel internal components for exceptional strength
• Complete kit includes replacement differential carrier, dash-mounted activation switch, solenoid valve, air line, and bulkhead fittings
• Retains normal open differential operation when not engaged for optimal on-road handling

The ARB Air Locker is the world's most popular aftermarket locking differential, trusted by off-road enthusiasts and professional competitors worldwide. Unlike limited-slip or automatic locking differentials, the Air Locker gives you complete control - activate it when you need maximum traction, and drive normally when you don't. Installation requires professional setup and an on-board air source such as an air compressor.
