ARB RD231 Air Locker Locking Differential - Kit

The ARB RD231 Air Locker is a pneumatically-activated locking differential that provides 100% traction on demand, allowing you to conquer challenging terrain with confidence. When engaged, the Air Locker mechanically locks both axle shafts together, forcing both wheels to turn at the same speed regardless of available traction. This eliminates wheel spin and maximizes forward momentum in mud, sand, snow, and rock crawling conditions.

Key Features:

• Pneumatic activation provides instant locking and unlocking capability from inside the vehicle
• Maintains factory-like performance on the highway when disengaged, with no impact on handling or tire wear
• Forged steel construction with high-strength gears for maximum durability in extreme conditions
• Compatible with both manual and automatic transmissions
• Engineered and manufactured to OEM specifications for reliable fit and performance

Complete Kit Includes:

• Air Locker differential assembly
• Dashboard-mounted activation switch
• Solenoid valve for air control
• Air line for pneumatic operation
• Bulkhead fittings for professional installation

ARB Air Lockers are trusted worldwide as the premier traction aid for off-road enthusiasts, professional operators, and anyone who demands maximum traction when conditions deteriorate. Unlike limited-slip differentials that rely on friction, the Air Locker provides positive mechanical engagement for guaranteed power delivery to both wheels.
