{"product_id":"3-73-posi-limited-slip-differential-2","title":"3.73 Posi Limited Slip Differential","description":"The Zumbrota Drivetrain RAA435-2111J-P is a remanufactured axle assembly built to rigorous quality standards for precision and reliability. This unit is designed for GM 7.5-inch differentials and comes with a 3.73 gear ratio and a Posi Limited Slip Differential (LSD). It is specifically engineered for the 1985-1995 GMC Astro and Safari van models.\n\nEach axle assembly undergoes thorough inspection for straightness, cracks, and surface wear. All internal components, including ring and pinions, internal gears, clutches, and carriers, are inspected and tested. To ensure optimal performance and longevity, all bearings and seals are replaced. The gears are meticulously inspected for ideal tooth contact patterns and correct rolling torque, with precise setup and quiet operation achieved through proper backlash settings. Additionally, axle tubes are 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 its internal and external parts, setting a benchmark for remanufactured axle assemblies. This specific model features a 7.6-inch ring gear, a 3.73 ratio, and includes a cover.","brand":"Zumbrota Drivetrain","offers":[{"title":"Default Title","offer_id":52870868369720,"sku":"RAA435-2111J-P","price":3765.0,"currency_code":"USD","in_stock":true}],"url":"https:\/\/store.motormia.co\/products\/3-73-posi-limited-slip-differential-2","provider":"MOTORMIA","version":"1.0","type":"link"}
