{"product_id":"quaife-atb-helical-differential-for-r200","title":"Quaife ATB Helical Differential for R200","description":"The Quaife QDF7L ATB Helical Differential is a precision-engineered performance upgrade designed to replace standard factory open differential units in Nissan R200 applications. By utilizing a gear-operated system rather than conventional clutch plates, this differential delivers smooth, progressive torque biasing that never locks harshly, significantly improving traction and handling balance while reducing understeer and oversteer during aggressive driving.\n\nConstructed from Corus steel billets using CNC machining and CAD design, this unit is inspected to ISO 9001 standards to ensure durability for road and motorsport use. It installs into R200 differentials commonly found in vehicles such as the Nissan 300ZX (Non-Turbo), 240SX (S13, S14), Infiniti J30, and JDM models including the Silvia and R32\/R33\/R34 Skylines.\n\nInstallation requires specific attention to compatibility: this unit is only compatible with 29-spline differential stub axle flanges. Users must verify the spline count of their specific axle stubs before purchase, as there are various stub axle variations for R200 differentials. Additionally, the installation requires the use of two short stub shafts.","brand":"Nissan","offers":[{"title":"Default Title","offer_id":52689307894072,"sku":"QDF7L","price":1285.5,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/687517547.jpg?v=1784904920","url":"https:\/\/store.motormia.co\/products\/quaife-atb-helical-differential-for-r200","provider":"MOTORMIA","version":"1.0","type":"link"}
