{"product_id":"4-10-gear-ratio-differential-assembly","title":"4.10 Gear Ratio Differential Assembly","description":"The Zumbrota Drivetrain RAA435-2255C is a remanufactured axle assembly specifically designed for GM 9.5-inch differentials, targeting the 2006-2009 Chevrolet Trailblazer SS equipped with the 6.0L engine.\n\nThis unit boasts a 4.10 gear ratio and is built to rigorous quality standards. Zumbrota Drivetrain thoroughly inspects each assembly for straightness, cracks, and surface wear. All internal components, including ring and pinions, internal gears, clutches, and carriers, undergo a 100% inspection. All bearings, seals, crush sleeves, pinion nuts, and shims are replaced as part of the remanufacturing process to ensure precision setup and longevity. The gears are inspected for optimal tooth contact patterns and correct rolling torque is established using inch-pound measurements, while correct gear backlash is set for proper lubrication and quiet operation.\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. All axle tubes are inspected to ensure they meet OEM standards for straightness. The housing is tested for surface wear and cracks, and all housings are cleaned using a state-of-the-art hydro blasting and rinsing process to restore them to an OEM finish. This axle assembly includes the differential cover, but the fluid is not included.\n\nThis specific assembly is confirmed to fit the 2006-2009 Chevrolet Trailblazer SS with the 6.0L engine.","brand":"Zumbrota Drivetrain","offers":[{"title":"Default Title","offer_id":52870895731000,"sku":"RAA435-2255C","price":3008.99,"currency_code":"USD","in_stock":true}],"url":"https:\/\/store.motormia.co\/products\/4-10-gear-ratio-differential-assembly","provider":"MOTORMIA","version":"1.0","type":"link"}
