{"product_id":"helical-limited-slip-differential-15","title":"Helical Limited Slip Differential","description":"The MFactory Helical Limited Slip Differential provides a competitive edge on the street, strip, or track by improving power transfer and traction. By utilizing advanced gear geometry developed through 3D CAD and FEA software, this torque-biasing differential helps transfer more power to the ground compared to stock components. The maintenance-free design eliminates the need for the special fluids and frequent rebuilds typically required by plate-type limited slip units.\n\nEngineered for durability, the unit is forged from SAE 4320 and SAE 9310 steel, which is double-tempered and super sub-zero treated to handle the extreme shock loads of competition-level drag racing.\n\nInstallation requires consideration for specific vehicle configurations. The unit will not directly fit BMW 135i (MT), 335i (2007+ MT\/DCT), or 335d models because the OEM ring gear is welded to the factory differential. For these specific applications, the ring gear must be machined to accept the new LSD, or a new bolted ring and pinion must be installed. MFactory offers professional services to meet OEM tolerances for this modification.","brand":"MFactory","offers":[{"title":"Default Title","offer_id":52689089921336,"sku":"SYNMF-TRS-05E92","price":1149.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/687382438.jpg?v=1784901689","url":"https:\/\/store.motormia.co\/products\/helical-limited-slip-differential-15","provider":"MOTORMIA","version":"1.0","type":"link"}
