This unit features a 3.15 gear ratio and a Posi Limited Slip Differential (LSD), designed to enhance traction and performance.\n\nZumbrota Drivetrain rebuilds these axle assemblies to high standards of precision and reliability. Each unit undergoes thorough inspection for structural integrity, including straightness and absence of cracks or surface wear. Internally, all components such as ring and pinions, gears, clutches, and carriers are rigorously inspected and tested. To ensure optimal function and durability, all bearings and seals are replaced, and gears are meticulously set for proper tooth contact patterns and correct rolling torque using precise inch-pound measurements.\n\nFurthermore, the correct gear backlash is established to guarantee adequate gear lubrication and quiet operation. Axle tubes are inspected to meet OEM standards for straightness. Zumbrota employs an exclusive hydro-blast rinse and sandblasting procedure, followed by a proprietary shot-peened deep cleaning process, setting a high standard for remanufactured axle assemblies.","brand":"Zumbrota Drivetrain","offers":[{"title":"Default Title","offer_id":52870873841976,"sku":"RAA435-212A-P","price":3098.89,"currency_code":"USD","in_stock":true}],"url":"https:\/\/store.motormia.co\/products\/3-15-posi-limited-slip-differential","provider":"MOTORMIA","version":"1.0","type":"link"}
