Fits select 2010-2024 Toyota 4Runner, 2010-2014 FJ Cruiser, and 2010-2012 Lexus GX460.

The ARB RD193 Air Locker is a premier traction aid designed to provide 100% locking capability at the flick of a switch. This pneumatically operated differential replacement allows you to tackle the most demanding terrain by preventing internal gears from rotating independently, ensuring both axle shafts turn in unison with the ring gear. When disengaged, the RD193 functions as a standard open differential, preserving factory on-road drivability and reducing driveline wear.

• High-Strength Design: Features an ultra-durable two-piece construction with minimal moving parts to ensure maximum trail reliability.
• Extreme Seals: Utilizes a steel-reinforced, elastomer-bonded annular seal engineered to withstand the most extreme climatic temperatures.
• Timed Locking: Patented locking mechanism offers high strength and ultra-fast engagement and unlocking.
• Complete Hardware Kit: Includes the Air Locker differential, 12V solenoid valve, dash-mounted activation switch, air line, and bulkhead fitting.
