Regular price $1,091.00



  • A fully machined one-piece nodular iron differential carrier case offers the rigidity of a one-piece factory differential with twice the standard number of pinion gears to cope with the torque.


  • A fully machined nodular iron flange cap incorporates the stationary side of ARBs tough, proven, and patented timed locking mechanism.


  •  High-grade surface treatments, nickel alloy steel, and ARB’s patented timed locking system make this the most "lockable" gear in the industry.


  • Forged gears and redefined tooth geometry, ARB's revolutionary design yields structural advantages of up to 30% over other available high-strength gears.


  • Provides 100% traction on demand without affecting road drivability or driveline wear. Vastly improved traction means less reliance on momentum, thus reducing the likelihood of vehicle damage and environmental impact.


  • Incredibly simple yet effective design that employs minimal moving parts, thereby ensuring maximum reliability. Thoroughly tested and proven design trusted and used in over 80 countries around the world.

Locking differentials have been available for years but were always a compromise, performing well either off the road or on the road - but not on both. The ARB Air Locker provides normal differential action on the street - maintaining safe, predictable handling. An ARB Air Locker differential will drive out of the most difficult situations. Easy-to-follow installation instructions are included in the kit.

Created to provide 100% traction on demand without sacrificing any of your vehicle's highway driving performance, ARB Air Lockers employ a 12 volt ARB Air Compressor designed to activate (and deactivate) a solid and durable locking mechanism inside the differential. This gives you the traction you need, when you need it, all at the flip of a switch and all within the comfort of the driver's seat.
