{"product_id":"gm-10-bolt-8-5-inch-3-73-posi-traction-rear-axle-assembly","title":"GM 10 Bolt 8.5 Inch 3.73 Posi Traction Rear Axle Assembly","description":"The Zumbrota Drivetrain RAA435-1215EE-P is a remanufactured rear axle assembly built to high standards of precision and reliability. Each assembly undergoes thorough inspection for straightness, cracks, and surface wear. Internal components, including ring and pinions, internal gears, clutches, and carriers, are fully inspected and tested. All bearings and seals are replaced, and gears are checked for optimal tooth contact patterns and correct rolling torque using inch-pound measurements for precise setup and longevity. Correct gear backlash is set for proper lubrication and quiet operation, and axle tubes are inspected to ensure OEM standards of straightness.\n\nZumbrota employs an exclusive hydro-blast rinse and sandblasting procedure, followed by a proprietary deep cleaning process, to ensure a like-new finish on all housings. This remanufacturing process guarantees that critical settings like rolling torque and gear backlash are precisely established, contributing to the longevity of the component.\n\nThis specific axle assembly is designed for 2WD 1978-1987 GM 1\/2 ton trucks and 1978-1988 GM 1\/2 ton Suburbans. It is configured with a GM 10 Bolt 8.5 inch ring gear, a 3.73 ratio (GT4 option), Posi Traction, and is suitable for 28 spline axles. Please note that this assembly does not include hubs, brakes, backing plates, or axle shafts.","brand":"Zumbrota Drivetrain","offers":[{"title":"Default Title","offer_id":52870735626552,"sku":"RAA435-1215EE-P","price":1869.89,"currency_code":"USD","in_stock":true}],"url":"https:\/\/store.motormia.co\/products\/gm-10-bolt-8-5-inch-3-73-posi-traction-rear-axle-assembly","provider":"MOTORMIA","version":"1.0","type":"link"}
