This unit features a 3.55 gear ratio, a robust 9.75-inch Ford ring gear, and a Posi Traction limited-slip differential for enhanced traction. It is configured for rear disc brakes and includes 12 mm wheel studs.\n\nThis axle assembly is built to Zumbrota Drivetrain's high standards, ensuring reliability and performance. The remanufacturing process involves a comprehensive inspection of all tubes for straightness and housings for cracks. Every internal component, including the ring and pinion gears, clutches, and carrier, is meticulously inspected and tested. Furthermore, all bearings, seals, crush sleeves, pinion nuts, and shims are replaced with new parts. The housings are restored to an OEM finish through a state-of-the-art hydro blasting process, and precise rolling torque is established for optimal setup and extended service life.\n\nIt is important to note that this assembly does not include hubs, brake components, backing plates, or axle shafts. The \"Check Tag\" designation indicates that verifying the specific tag number (S919A for this unit) on your original axle is crucial for ensuring correct fitment. This product is built to order and includes a refundable core charge.","brand":"Zumbrota Drivetrain","offers":[{"title":"Default Title","offer_id":52870831866168,"sku":"RAA435-2031B-P","price":2457.89,"currency_code":"USD","in_stock":true}],"url":"https:\/\/store.motormia.co\/products\/reman-axle-assembly-rear-disc-posi-traction-3-55-gear-ratio","provider":"MOTORMIA","version":"1.0","type":"link"}
