{"product_id":"chrysler-9-25-inch-3-21-posi-limited-slip-differential","title":"Chrysler 9.25-inch 3.21 Posi Limited Slip Differential","description":"The Zumbrota Drivetrain RAA435-1542A-P is a remanufactured axle assembly designed for Chrysler 9.25-inch differentials, specifically for 1991-1993 Dodge D150, W150, and Ramcharger models. This unit features a 3.21 gear ratio and a Posi Limited Slip Differential for enhanced traction and performance.\n\nZumbrota Drivetrain prioritizes precision and reliability in their remanufacturing process. Each axle assembly undergoes a thorough inspection for straightness, cracks, and surface wear. All internal components, including ring and pinions, internal gears, clutches, and carriers, are meticulously inspected and tested. To ensure longevity and optimal performance, all bearings, seals, crush sleeves, pinion nuts, and shims are replaced. The gears are inspected for ideal tooth contact patterns and precise rolling torque measurements, with backlash set to guarantee proper gear lubrication and quiet operation. The axle tubes are also inspected to meet OEM standards for straightness.\n\nZumbrota employs an exclusive hydro-blast rinse and sandblasting procedure, followed by a proprietary shot-enticed deep cleaning process for both internal and external parts. This comprehensive cleaning method sets a high standard for axle assembly remanufacturing, restoring housings to an OEM finish. The axle type for this assembly is Semi Floating. A cover is included with this assembly, but the necessary differential fluid is not. The gear ratio is precisely set at 3.21.","brand":"Zumbrota Drivetrain","offers":[{"title":"Default Title","offer_id":52870748963128,"sku":"RAA435-1542A-P","price":2439.99,"currency_code":"USD","in_stock":true}],"url":"https:\/\/store.motormia.co\/products\/chrysler-9-25-inch-3-21-posi-limited-slip-differential","provider":"MOTORMIA","version":"1.0","type":"link"}
