ARB RD153 Air Locker Locking Differential

The ARB RD153 Air Locker is a pneumatically-activated locking differential designed to provide maximum traction in challenging off-road conditions. When engaged, the Air Locker locks both wheels on an axle together, forcing them to rotate at the same speed regardless of available traction. This ensures power is delivered to both wheels equally, preventing wheel spin and keeping you moving through mud, sand, snow, and rock.

Key Features:

• Pneumatic activation provides instant engagement and disengagement via dash-mounted switch
• Seamless operation—unlocked, the differential functions as a standard open differential for normal driving
• Heavy-duty construction with forged steel internals for exceptional strength and durability
• Complete kit includes replacement differential carrier, electronic activation switch, air solenoid valve, air line, and bulkhead fittings
• Proven design trusted by off-road enthusiasts and professional competitors worldwide

The ARB Air Locker delivers superior traction control compared to limited-slip differentials, making it ideal for serious four-wheel drive vehicles tackling extreme terrain. Installation requires differential disassembly and an on-board air source for activation.
