ARB RD165 Air Locker Differential for Ultimate Off-Road Traction

The ARB RD165 Air Locker Differential delivers 100% traction on demand without compromising highway driving performance. This pneumatically operated locking differential features ARB's improved two-piece design with forged gears for enhanced durability and reliability, all backed by an industry-leading five-year warranty.

How It Works:

The ARB Air Locker employs a 12-volt ARB Air Compressor to activate and deactivate a solid locking mechanism inside the differential. When engaged, the Air Locker 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, maintaining maximum traction even when one wheel loses grip. When unlocked, the unit operates like a conventional open differential for normal driving conditions.

Key Features:

• On-demand activation via dashboard-mounted switch for convenient driver control
• Two-piece design with forged gears for superior strength
• Pneumatic operation provides reliable engagement and disengagement
• Maintains factory highway driving characteristics when unlocked
• Allows slower, more controlled driving off-road to reduce vehicle damage and environmental impact
• Five-year manufacturer warranty for peace of mind

The ARB Air Locker transforms your 4x4's off-road capabilities by providing true traction control exactly when you need it, making it ideal for rock crawling, mud, sand, snow, and any challenging terrain where wheel slip occurs.
