{"product_id":"air-locker-for-dana-44-30-spline-3-73-down","title":"Air Locker for Dana 44 30 Spline 3.73 \u0026 Down","description":"The ARB Air Locker is a premier traction aid that keeps you moving in all conditions by providing 100 percent traction on demand. With the flick of a switch, it offers instant lock at any speed, allowing you to tackle the toughest terrain. This pneumatically operated system prevents internal differential gears from rotating independently, ensuring both wheels are tied directly to the ring gear for maximum possible traction. When unlocked, it operates like a conventional open differential, allowing for slower, safer, and more controlled driving, reducing the likelihood of vehicle damage.\n\nKey features include a two-piece, ultra-durable design with minimal moving parts for maximum reliability and a patented 'timed' locking mechanism for high strength and ultra-fast unlocking. The kit includes the Air Locker differential, activation switch, solenoid valve, air line, and bulkhead fitting. An air compressor is required for operation and sold separately.\n\nThis ARB Air Locker is specifically designed for Dana 44 axles with 30 splines and 3.73 \u0026amp; down gear ratios. It is not compatible with Jeep JK models. For aftermarket Dana 44 ring and pinion ratios of 4.56 and up, the RD116 is required instead. Thick cut ring and pinion sets, regardless of ratio, will require the use of the RD117. Additionally, newer OEM Chrysler 8.25\" and Dana 44 ring gears may have different bolt sizes, potentially requiring the Air Locker flange holes to be drilled or reamed larger to suit 7\/16\" or 1\/2\" bolts.","brand":"ARB","offers":[{"title":"Default Title","offer_id":52686960591160,"sku":"ARB-117","price":3095.75,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/662150158.jpg?v=1784878977","url":"https:\/\/store.motormia.co\/products\/air-locker-for-dana-44-30-spline-3-73-down","provider":"MOTORMIA","version":"1.0","type":"link"}
