ARB RD150 Air Locker Locking Differential - Kit

The ARB RD150 Air Locker is a pneumatically-activated locking differential designed to provide maximum traction in challenging off-road conditions. When engaged, the Air Locker mechanically locks the differential, ensuring both wheels on an axle turn together at the same speed, delivering 100% of available torque to both wheels regardless of traction conditions.

Key Features:

• On-demand activation via dashboard-mounted switch for instant traction control
• Pneumatic engagement system eliminates wiring complexity and heat buildup
• Seamless operation—locks and unlocks smoothly without jerking or grinding
• Legendary ARB reliability with proven performance in extreme conditions
• Complete kit includes replacement differential carrier, air compressor line, solenoid valve, activation switch, bulkhead fittings, and all necessary hardware

ARB Air Lockers are trusted by professional off-roaders, expedition vehicles, and rock crawlers worldwide. Unlike limited-slip differentials that rely on friction and wear over time, the Air Locker provides consistent, repeatable performance whether you're navigating deep mud, loose sand, steep rock faces, or snow-covered trails. When unlocked, the differential operates as a standard open differential for normal on-road driving characteristics.
