The advantage of the Air Locker lies in the pneumatically operated locking system inside the differential. When activated, the Air Locker prevents the internal differential gears from rotating and therefore prevents the axle shafts from turning independently of each other. With both wheels tied directly to the rotation of the ring gear, the vehicle maintains maximum possible traction at all times. When unlocked, it operates like a conventional open differential. An Air Locker equipped vehicle can be driven in a slower, safer and more controlled manner, greatly reducing the likelihood of vehicle damage and environmental impact.\u003c\/p\u003e\u003c!--\/mt-sema-20260914--\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand:\u003c\/strong\u003e ARB\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePart number:\u003c\/strong\u003e RD139\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRequires:\u003c\/strong\u003e air compressor (sold separately)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFinish:\u003c\/strong\u003e Silver\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial:\u003c\/strong\u003e Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWarranty:\u003c\/strong\u003e 5 years (manufacturer)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShipping carton:\u003c\/strong\u003e 11 × 11 × 11 in (28 × 28 × 28 cm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShipping weight:\u003c\/strong\u003e 25.9 kg (57 lb)\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ARB","offers":[{"title":"Default Title","offer_id":48857973883072,"sku":"ARBRD139","price":1910.93,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0762\/4772\/8320\/files\/RD139_v2.jpg?v=1787295774","url":"https:\/\/mapletorque.ca\/products\/air-locker-differential-silver-rd139","provider":"MapleTorque","version":"1.0","type":"link"}
