{"product_id":"3-55-ratio-rear-differential-assembly","title":"3.55 Ratio Rear Differential Assembly","description":"The Zumbrota Drivetrain RAA435-2268F is a remanufactured rear differential assembly, precision-rebuilt to meet high standards of quality and reliability. This assembly is designed for Chrysler 9.25ZF axles, featuring a 3.55 gear ratio and a 9.25-inch ring gear diameter with a 12-bolt cover. It is built by ZF and specifically configured without Posi Traction.\n\nEach Zumbrota axle assembly undergoes rigorous inspection. Internal components, including ring and pinions, gears, clutches, and carriers, are thoroughly tested. All bearings and seals are replaced to ensure optimal performance. The gears are meticulously inspected for proper tooth contact patterns and set to the correct rolling torque using inch-pound measurements for maximum precision and extended lifespan. Proper gear backlash is established to guarantee adequate gear lubrication and quiet operation.\n\nZumbrota's remanufacturing process includes inspecting axle tubes for OEM standards of straightness. They employ an exclusive hydro-blast rinse and sandblasting procedure on all internal and external parts, followed by a proprietary shot-enticed deep cleaning method, setting a benchmark for axle assembly remanufacturing. Key specifications include a 9.25-inch ring gear diameter, a 12-bolt cover, and a 3.55 gear ratio. The axle type is semi-floating, and the cover is included. The fluid capacity is 2.35, but fluid and mounting hardware are not included.","brand":"Zumbrota Drivetrain","offers":[{"title":"Default Title","offer_id":52870899007800,"sku":"RAA435-2268F","price":3016.89,"currency_code":"USD","in_stock":true}],"url":"https:\/\/store.motormia.co\/products\/3-55-ratio-rear-differential-assembly","provider":"MOTORMIA","version":"1.0","type":"link"}
