Using a pneumatically operated locking system inside the differential that, when activated, locks the internal gears together, preventing independent axle shaft rotation and ensuring both wheels turn at the same speed. This provides maximum traction in extreme terrain while allowing precise driver control. When unlocked, it functions like a conventional open differential which is ideal for street use and high speed maneuverability.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eKit Includes:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eARB Ford 9\" Custom Air Locker Differential\u003c\/li\u003e\n\u003cli\u003eDash activation switch\u003c\/li\u003e\n\u003cli\u003eSolenoid valve\u003c\/li\u003e\n\u003cli\u003eAir line\u003c\/li\u003e\n\u003cli\u003eBulkhead fitting\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003eNotes: \u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003ca href=\"\/products\/arb-compressor-twin-12v\"\u003eAir compressor \u003c\/a\u003erequired for operation (sold separately).\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCustom axle shafts are required \u003c\/strong\u003eand must be matched to your specific housing, spline count, and application\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003chr\u003e\n\u003cdetails class=\"details\"\u003e\n\u003csummary class=\"details__header\"\u003e\u003cstrong\u003eSpecifications\u003c\/strong\u003e\u003cspan class=\"svg-wrapper icon-plus\"\u003e\u003csvg xmlns=\"http:\/\/www.w3.org\/2000\/svg\" fill=\"none\" viewbox=\"0 0 14 14\" height=\"14\" width=\"14\"\u003e\u003cpath stroke-linecap=\"round\" stroke-width=\"var(--icon-stroke-width)\" stroke=\"currentColor\" d=\"M2.75 7H11.25\" class=\"vertical\"\u003e\u003c\/path\u003e\u003cpath stroke-linecap=\"round\" stroke-width=\"var(--icon-stroke-width)\" stroke=\"currentColor\" d=\"M7 2.75L7 11.25\" class=\"horizontal\"\u003e\u003c\/path\u003e\u003c\/svg\u003e\u003c\/span\u003e\u003c\/summary\u003e\n\u003cdiv class=\"details-content rte\"\u003e\n\u003cul\u003e\n\u003cli\u003eDifferential Type: Selectable Air Locker\u003c\/li\u003e\n\u003cli\u003eAxle Type: Ford 9\" Custom\u003c\/li\u003e\n\u003cli\u003eApplication: Performance \/ Custom axle builds\u003c\/li\u003e\n\u003cli\u003eMaterial: Steel\u003c\/li\u003e\n\u003cli\u003eDesign: Two-piece carrier\u003c\/li\u003e\n\u003cli\u003eActivation: Pneumatic (air-operated)\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/div\u003e\n\u003c\/details\u003e\n\u003chr\u003e\n\u003cdetails class=\"details\"\u003e\n\u003csummary class=\"details__header\"\u003e\u003cstrong\u003eFitment\u003c\/strong\u003e\u003cspan class=\"svg-wrapper icon-plus\"\u003e\u003csvg xmlns=\"http:\/\/www.w3.org\/2000\/svg\" fill=\"none\" viewbox=\"0 0 14 14\" height=\"14\" width=\"14\"\u003e\u003cpath stroke-linecap=\"round\" stroke-width=\"var(--icon-stroke-width)\" stroke=\"currentColor\" d=\"M2.75 7H11.25\" class=\"vertical\"\u003e\u003c\/path\u003e\u003cpath stroke-linecap=\"round\" stroke-width=\"var(--icon-stroke-width)\" stroke=\"currentColor\" d=\"M7 2.75L7 11.25\" class=\"horizontal\"\u003e\u003c\/path\u003e\u003c\/svg\u003e\u003c\/span\u003e\u003c\/summary\u003e\n\u003cdiv class=\"details-content rte\"\u003e\n\u003cul\u003e\n\u003cli\u003eAxle: Ford 9\"\u003c\/li\u003e\n\u003cli\u003eApplication Type: Performance \/ Custom Builds\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003eImportant Fitment Notes:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003ePerformance application models do \u003cstrong\u003eNOT \u003c\/strong\u003eaccept original equipment axle shafts\u003c\/li\u003e\n\u003cli\u003eCustom axle shafts are required and must be matched to your specific housing, spline count, and application\u003c\/li\u003e\n\u003cli\u003eCan be manually modified to accept some alternate axle spline configurations (builder-level modification)\u003c\/li\u003e\n\u003cli\u003eThis Air Locker is intended for aftermarket housings, custom third members, and race\/off-road builds, not factory Ford 9\" assemblies.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/div\u003e\n\u003c\/details\u003e\n\u003chr\u003e\n\u003cdetails class=\"details\"\u003e\n\u003csummary class=\"details__header\"\u003e\u003cstrong\u003eTech Insight\u003c\/strong\u003e\u003cspan class=\"svg-wrapper icon-plus\"\u003e\u003csvg xmlns=\"http:\/\/www.w3.org\/2000\/svg\" fill=\"none\" viewbox=\"0 0 14 14\" height=\"14\" width=\"14\"\u003e\u003cpath stroke-linecap=\"round\" stroke-width=\"var(--icon-stroke-width)\" stroke=\"currentColor\" d=\"M2.75 7H11.25\" class=\"vertical\"\u003e\u003c\/path\u003e\u003cpath stroke-linecap=\"round\" stroke-width=\"var(--icon-stroke-width)\" stroke=\"currentColor\" d=\"M7 2.75L7 11.25\" class=\"horizontal\"\u003e\u003c\/path\u003e\u003c\/svg\u003e\u003c\/span\u003e\u003c\/summary\u003e\n\u003cdiv class=\"details-content rte\"\u003e\n\u003cp\u003eARB’s patented timed locking mechanism provides ultra-fast disengagement under load, minimizing driveline stress while maintaining exceptional strength.
