It comes equipped with a 4.10 gear ratio and Posi Traction for enhanced performance and grip.\n\nEach unit is meticulously rebuilt, with comprehensive inspection and replacement of critical components. Housings are tested for surface wear and cracks, while internal parts like ring and pinion gears, clutches, and carriers are subject to a 100% inspection. To ensure longevity and proper function, all bearings, seals, crush sleeves, pinion nuts, and shims are replaced. The hydro blasting and rinsing process used to clean the housings restores them to an OEM finish, and correct rolling torque is established using precise inch-pound measurements.\n\nThis axle assembly is built to order and ships when ready, with options for expedited shipping. A refundable core charge of +$600 applies, which is returned upon receipt of your old, salvageable part. Zumbrota Drivetrain offers robust support, including live chat and phone assistance for fitment questions or build project selection.","brand":"Zumbrota Drivetrain","offers":[{"title":"Default Title","offer_id":52870911230264,"sku":"RAA440-1534D-P","price":2499.89,"currency_code":"USD","in_stock":true}],"url":"https:\/\/store.motormia.co\/products\/9-75-inch-irs-rear-axle-assembly-4-10-posi-traction","provider":"MOTORMIA","version":"1.0","type":"link"}
