Zumbrota Drivetrain has been in business for over 30 years, focusing on transmissions, transfer cases, and differentials.\n\nThis specific axle assembly is designed for the Ford 9.75\" differential and features a 3.55 gear ratio, a stepped housing, and is configured for rear drum brakes. It comes with 14mm wheel studs and 2.533\" O.D. wheel bearings. The internal components, including ring and pinions, gears, clutches, and carriers, undergo a 100 percent inspection. Bearings, seals, crush sleeves, pinion nuts, and shims are all replaced during the remanufacturing process. Housings are cleaned using a hydro blasting process to restore them to an OEM finish. Gear patterns are checked for optimum tooth contact, and the correct rolling torque and backlash clearance are set for longevity and noise reduction.\n\nThis axle assembly is specifically designed to fit the 2000 Ford F-150 models with 2WD\/4WD Gas drivetrains. It is important to note that this assembly is for models without Posi-Traction. The \"Important Notes\" section on the product page also lists a ratio of 3.31 for a similar Ford 9.75 Inch Ring Gear, Rear Drum Brakes, 14 mm Wheel Studs, Stepped Tube Housing, Tag Number: S916C, With Posi Traction, and states it \"Does Not Include Hubs, Brakes, Backing Plates, Or Axle Shafts\", which may indicate variations or specific components not included with this particular RAA435-2021A-P unit, though this unit is specified as \"Without Posi-Traction\". A refundable core charge will be added to the purchase price.","brand":"Zumbrota Drivetrain","offers":[{"title":"Default Title","offer_id":52870821904696,"sku":"RAA435-2021A-P","price":2599.89,"currency_code":"USD","in_stock":true}],"url":"https:\/\/store.motormia.co\/products\/3-55-ratio-rear-axle-assembly-1","provider":"MOTORMIA","version":"1.0","type":"link"}
