{"product_id":"helical-limited-slip-differential-10","title":"Helical Limited Slip Differential","description":"Designed using Solidworks 3D CAD and Cosmos FEA software, the differential features advanced gear geometry that reduces parasitic drivetrain losses, potentially transferring more power to the ground than standard open differentials.\n\nBuilt for extreme durability, the unit is diamond-cut from forged Japanese SAE 4320 and SAE 9310 steel. It undergoes double tempering, a super sub-zero treatment, and advanced shot peening to increase surface hardness and withstand the shock loads of competitive drag racing.\n\nFitment depends heavily on the specific BMW model and production date. For many models, such as the E36, E39, E46, and non-35i E8X\/E9X\/E60 variants, this is a direct bolt-on replacement. However, it does NOT fit models with a welded-on OEM ring gear, including 335i MT\/DCT models produced after 03\/2007, 335d, F20, and F30 variants. For these incompatible configurations, the OEM crown wheel must be welded to the new differential or a new MFactory final drive gear set must be fitted. Professional installation and fluid changes after the first 300-400 miles are recommended.","brand":"MFactory","offers":[{"title":"Default Title","offer_id":52689089331512,"sku":"MF-TRS-05E92","price":841.89,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/687381550.jpg?v=1784901665","url":"https:\/\/store.motormia.co\/products\/helical-limited-slip-differential-10","provider":"MOTORMIA","version":"1.0","type":"link"}
