{"product_id":"3-73-posi-lsd-14-bolt-differential-assembly","title":"3.73 Posi LSD 14 Bolt Differential Assembly","description":"The Zumbrota Drivetrain RAA435-1655B is a remanufactured axle assembly, meticulously rebuilt to meet high standards of precision and reliability for GM 14 Bolt trucks. This specific unit is configured with a 3.73 gear ratio and a Posi Limited Slip Differential (LSD) for enhanced traction.\n\nThis axle assembly is engineered for 1990-2000 GM 2500 and 3500 trucks, particularly those with a VIN K designation in the pickup configuration. It is also confirmed to be for 4x4 applications.\n\nDuring the 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 fully inspected and tested. Crucially, all bearings and seals are replaced with new parts. The gears are meticulously inspected for optimal tooth contact patterns and correct rolling torque, measured in inch-pounds for precise setup and longevity. Proper gear backlash is set to ensure adequate gear lubrication and quiet operation. Axle tubes are inspected and straightened to OEM standards. Zumbrota employs an exclusive hydro-blast rinse and sandblasting procedure, followed by a proprietary shot-enticed deep cleaning process, setting a high standard for axle assembly remanufacturing.","brand":"Zumbrota Drivetrain","offers":[{"title":"Default Title","offer_id":52870759416120,"sku":"RAA435-1655B","price":3402.29,"currency_code":"USD","in_stock":true}],"url":"https:\/\/store.motormia.co\/products\/3-73-posi-lsd-14-bolt-differential-assembly","provider":"MOTORMIA","version":"1.0","type":"link"}
