Compressed air engages a 100% mechanical lock across the Dana 70\/80 37-spline centre for maximum traction on demand, then releases for predictable, road-friendly manners the rest of the time.\u003c\/p\u003e\u003cp\u003eEach Air Locker is built around a forged, heat-treated case with hardened internals, engineered to handle high-torque and big-tyre abuse without giving up everyday drivability. Unlike an automatic locker, engagement is 100% driver-controlled — you decide exactly when the axle locks. Note that an air source (an ARB compressor or other on-board air) is required to operate it.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003ctable\u003e\n\u003cthead\u003e\u003ctr\u003e\n\u003cth\u003eSpecification\u003c\/th\u003e\n\u003cth\u003eDetail\u003c\/th\u003e\n\u003c\/tr\u003e\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003cth scope=\"row\"\u003eDifferential\u003c\/th\u003e\n\u003ctd\u003eDana 70\/80\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth scope=\"row\"\u003eSpline Count\u003c\/th\u003e\n\u003ctd\u003e37\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth scope=\"row\"\u003eRatio Group\u003c\/th\u003e\n\u003ctd\u003eHigh speed\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth scope=\"row\"\u003eActuation\u003c\/th\u003e\n\u003ctd\u003eAir-operated (compressed air, ~100 psi)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth scope=\"row\"\u003eLocker Type\u003c\/th\u003e\n\u003ctd\u003eFull 100% selectable locking differential\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth scope=\"row\"\u003eAir Source Required\u003c\/th\u003e\n\u003ctd\u003eYes – ARB compressor or on-board air\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth scope=\"row\"\u003eManufacturer Part No. (MPN)\u003c\/th\u003e\n\u003ctd\u003eRD175\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth scope=\"row\"\u003eGTIN\u003c\/th\u003e\n\u003ctd\u003e9332018015532\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth scope=\"row\"\u003eBrand\u003c\/th\u003e\n\u003ctd\u003eARB\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth scope=\"row\"\u003eWarranty\u003c\/th\u003e\n\u003ctd\u003e5-year ARB Air Locker warranty\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\u003cp\u003e\u003cstrong\u003eFitment:\u003c\/strong\u003e matched to the 37-spline, high-speed ratio group.
