This low speed carrier version is intended for performance applications and requires custom axle shafts to suit your specific axle assembly.\u003c\/p\u003e\n\u003cp\u003eUsing a pneumatically operated locking mechanism, the ARB Air Locker completely locks the differential when activated, preventing the internal gears from rotating independently. This forces both axle shafts to turn together with the ring gear, providing maximum traction exactly when it’s needed. When disengaged, the differential functions like a standard open unit, maintaining predictable handling, reduced driveline wear, and smooth street manners.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eIncludes:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eARB Dana 70 \u0026amp; Dana 80 Air Locker differential\u003c\/li\u003e\n\u003cli\u003eDash mounted 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\u003cli\u003e\n\u003cstrong\u003e\u003ca href=\"\/products\/arb-compressor-twin-12v\"\u003eAir compressor\u003c\/a\u003e\u003c\/strong\u003e required for operation (sold separately).\u003c\/li\u003e\n\u003cli\u003e\n\u003cmeta charset=\"utf-8\"\u003ePerformance application models \u003cstrong\u003edo not \u003c\/strong\u003efit original equipment axle shafts.\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 width=\"14\" height=\"14\" viewbox=\"0 0 14 14\" fill=\"none\" xmlns=\"http:\/\/www.w3.org\/2000\/svg\"\u003e\u003cpath class=\"vertical\" d=\"M2.75 7H11.25\" stroke=\"currentColor\" stroke-width=\"var(--icon-stroke-width)\" stroke-linecap=\"round\"\u003e\u003c\/path\u003e\u003cpath class=\"horizontal\" d=\"M7 2.75L7 11.25\" stroke=\"currentColor\" stroke-width=\"var(--icon-stroke-width)\" stroke-linecap=\"round\"\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\u003eBrand: ARB\u003c\/li\u003e\n\u003cli\u003eDifferential Type: Selectable locking differential\u003cmeta charset=\"utf-8\"\u003e\n\u003c\/li\u003e\n\u003cli data-processed=\"true\" data-hveid=\"CAMQAQ\" data-sfc-cb=\"\" class=\"dF3vjf\"\u003e\u003cspan data-processed=\"true\" data-sfc-cb=\"\" data-sfc-cp=\"\" class=\"T286Pc\"\u003e\u003cspan class=\"Yjhzub\"\u003eAxle:\u003c\/span\u003e\u003cspan\u003e \u003c\/span\u003eDana 70X\/80X \u003c\/span\u003e\u003c\/li\u003e\n\u003cli data-processed=\"true\" data-hveid=\"CAMQAQ\" data-sfc-cb=\"\" class=\"dF3vjf\"\u003e\u003cspan data-processed=\"true\" data-sfc-cb=\"\" data-sfc-cp=\"\" class=\"T286Pc\"\u003eAxle Location: Rear\u003c\/span\u003e\u003c\/li\u003e\n\u003cli data-processed=\"true\" data-hveid=\"CAMQAQ\" data-sfc-cb=\"\" class=\"dF3vjf\"\u003e\u003cspan data-processed=\"true\" data-sfc-cb=\"\" data-sfc-cp=\"\" class=\"T286Pc\"\u003eSpline Count: 40\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003eCarrier Type: \u003cmeta charset=\"utf-8\"\u003e \u003cspan\u003e4.56 and Up\u003c\/span\u003e (Performance Application)\u003c\/li\u003e\n\u003cli\u003eActivation: Pneumatic (air operated)\u003c\/li\u003e\n\u003cli\u003eMaterial: Steel\u003c\/li\u003e\n\u003cli\u003eSeal Design: Steel reinforced, elastomer bonded annular seal\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 width=\"14\" height=\"14\" viewbox=\"0 0 14 14\" fill=\"none\" xmlns=\"http:\/\/www.w3.org\/2000\/svg\"\u003e\u003cpath class=\"vertical\" d=\"M2.75 7H11.25\" stroke=\"currentColor\" stroke-width=\"var(--icon-stroke-width)\" stroke-linecap=\"round\"\u003e\u003c\/path\u003e\u003cpath class=\"horizontal\" d=\"M7 2.75L7 11.25\" stroke=\"currentColor\" stroke-width=\"var(--icon-stroke-width)\" stroke-linecap=\"round\"\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\u003eDana 70 axle applications\u003c\/li\u003e\n\u003cli\u003eDana 80 axle applications\u003c\/li\u003e\n\u003cli\u003ePerformance application only\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cmeta charset=\"utf-8\"\u003e\u003cstrong\u003eImportant Application Note:\u003c\/strong\u003e Performance application models do not fit original equipment axle shafts.
