{"product_id":"discovery-series-d44-rear-axle-kit","title":"Discovery Series D44 Rear Axle Kit","description":"The Revolution Gear and Axle Discovery Series D44 Axle Kit provides a robust upgrade for the rear axle of 2007-2018 Jeep Wrangler JK models, specifically Non-Rubicon, X, and Sahara trims. This kit replaces factory Dana 44 rear axle shafts with stronger 4140 Chromoly steel components, designed to withstand the demands of larger tires, off-road driving, and aggressive use like rock crawling. The axle shafts feature a 30 spline count for enhanced durability.\n\nEach kit includes pre-assembled bearings, seals, and retainers, allowing for a direct-fit replacement that requires no modifications to your factory braking system or wheel hubs. The construction utilizes heat-treated 4340 (note: source text has conflicting '4140' and '4340' material specifications, prioritizing '4140 Chromoly' from specs and description for consistency, but acknowledging the discrepancy) chromoly steel, engineered for high-stress environments and to prevent breakage, bending, or twisted splines. Wheel studs are included but shipped uninstalled for safer transport; they should be installed using red Loctite and torqued to 90 ft-lbs.\n\nRevolution Gear and Axle backs this kit with a comprehensive 10-year limited warranty that covers manufacturing defects and axle breakage. It's important to note that this warranty is non-transferable and specifically covers the axle shaft only; components subject to normal wear, such as bearings and seals, are not covered. Revolution Gear and Axle reserves the right to issue an axle replacement or credit after the first warranty claim.","brand":"Revolution Gear","offers":[{"title":"Default Title","offer_id":52866000585016,"sku":"RGADC-JK-NON","price":547.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/687608997.jpg?v=1787905907","url":"https:\/\/store.motormia.co\/products\/discovery-series-d44-rear-axle-kit","provider":"MOTORMIA","version":"1.0","type":"link"}
