Description
Allows for Full Locking and Unlocking of your F150’s Front End at Will
Being able to selectively lock and unlock your F150’s front end is an absolute God-send for aggressive trucks that see both on-road driving applications and extreme off-roading, and the ARB Air Locker Locking Front Differential can make it happen. The ARB Air Locker (like its name implies) uses compressed air to lock your F150’s 8.8″ IFS front end, giving you equal power distribution to both of your F150’s front tires when you’re off the beaten path, all while allowing you to unlock the differential for street driving. The end result is a front differential that can help your F150 tackle the toughest off-road applications on the planet, while still allowing you maintain excellent street drivability and fuel economy. The ARB Air Locker Front Differential comes with everything you need to swap out your F150’s stock differential. All you’ll need is an ARB air compressor kit, and you’ll be able to get untold off-road traction with OEM on-road ride quality in a single differential kit.
Strong, Two-Piece Case Design with Forged Steel Internal Gears
ARB’s Air Locker Front Differential was born and bred in the Australian Outback, and features an incredibly durable design that allows it to handle even the most aggressive and tough off-road applications on the planet. The Air Locker is air actuated from your choice of ARB air compressor using an included rocker switch and solenoid system. When activated, the Air Locker’s two-piece design slides together to lock your F150’s front axles together to provide your truck with awesome traction for off-road applications. The Air Locker features an incredibly durable construction with fully forged internal gears and a two-piece case design that limits the amount of moving parts for improved reliability and performance over other locking differential designs. Each Air Locker even comes backed by a 5-year limited warranty from ARB with no mileage limit. Each Air Locker Kit comes with everything you need except for a required on-board air compressor. Drilling Required: this differential requires drilling into your F150’s axle to run its airline and for mounting the solenoids, as well as interior cutting for mounting its rocker switch. For 8.8″ IFS 31-Spline Front Ends: this differential only fits Ford 8.8″ 31-Spline Front IFS applications like those found on the fronts of 2009-2025 F150 4WD models. Inner axle length: after installation, if your inner axles have too much play in the air locker, they have require machining in order to avoid axle seal failure. Please test your inner axle shafts before completing your installation. Compressor Not Included: this differential does not come with an air compressor, and one of the following ARB Air Compressors will be required for installation and operation:
- ARB Compact Air Compressor Kit: provides adequate airflow for Air Locker operation, and can be used for up to two ARB Air Lockers.
- ARB High-Output Air Compressor Kit: provides excellent airflow and can support up to two Air Lockers, as well as handle tire inflation and light-duty air tools if paired with an air tank. Also features a waterproof design.
- ARB Dual High-Output Air Compressor Kit: provides huge amounts of airflow, and can support the inflation of extremely large tires or handle consistent air tool use when paired with a tank. Does not include an ARB Air Locker Manifold System, and one will need to be purchased separately.
