{"product_id":"4-10-ratio-posi-limited-slip-differential","title":"4.10 Ratio Posi Limited Slip Differential","description":"The Zumbrota Drivetrain RAA435-1978B-P is a remanufactured axle assembly specifically designed for Ford 10.5\" rear axles found in 1999-2000 Ford Excursion models. This assembly comes pre-configured with a 4.10 gear ratio, is intended for Single Rear Wheel (SRW) applications, and features a Posi Limited Slip Differential (LSD) for enhanced traction.\n\nEach Zumbrota axle assembly undergoes a rigorous remanufacturing process to meet high standards of precision and reliability. All tubes are inspected and straightened to OEM specifications, and housings are tested for surface wear and cracks. Internals, including ring and pinion gears, clutches, and carriers, receive a 100% inspection. Critical wear components such as bearings, seals, crush sleeves, pinion nuts, and shims are all replaced with new parts. The housings are meticulously cleaned using a hydro blasting and rinsing process to restore them to an OEM finish. Furthermore, the correct rolling torque is established using precise inch-pound measurements to ensure optimal setup and longevity.","brand":"Zumbrota Drivetrain","offers":[{"title":"Default Title","offer_id":52870811025720,"sku":"RAA435-1978B","price":1436.99,"currency_code":"USD","in_stock":true}],"url":"https:\/\/store.motormia.co\/products\/4-10-ratio-posi-limited-slip-differential","provider":"MOTORMIA","version":"1.0","type":"link"}
