{"product_id":"custom-differential","title":"Custom Differential","description":"The BimmerWorld differential is a custom-built unit crafted by Diffsonline for BMW E38 1995 740 vehicles. These differentials are assembled in-house, beginning with a thorough cleaning of the housing, followed by the selection of premium industry-standard ring and pinion gears. The process includes the application of desired clutch packs and options, culminating in a carefully assembled unit ready for delivery.\n\nWhen selecting your custom differential, the primary consideration is the gear ratio, which dictates engine RPMs for a given speed. Diffsonline offers an RPM\/MPH chart in their Technical Information section to help you understand the performance impact of various ratios. You can also specify the degree of limited slip desired, with options ranging from open to 75% and variable ramp lockups, along with the amount and type of clutches for the differential.\n\nFurther customization is available through upgrade options such as ring and pinion polishing to reduce friction and lower operating temperatures. Additional enhancements include upgraded rear covers and the selection of miscellaneous bolts and fluids to complete your build. All differentials are built to order, with current lead times of 6-8 weeks from order date to ship date.","brand":"BimmerWorld","offers":[{"title":"Default Title","offer_id":52687129772344,"sku":"621f58187c617","price":1399.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/661662993.webp?v=1784880671","url":"https:\/\/store.motormia.co\/products\/custom-differential","provider":"MOTORMIA","version":"1.0","type":"link"}
