10.5" 3.73 Posi Limited Slip Differential

The Zumbrota Drivetrain RAA435-1976D-P is a remanufactured complete axle assembly designed for the 1999 Ford F-250 and F-350 Super Duty models. This axle assembly features a 10.5-inch ring gear, a 3.73 gear ratio, and a Posi Limited Slip Differential (LSD) for enhanced traction. All tubes are straightened to OEM specifications, and housings undergo testing for surface wear and cracks. Internal components such as the ring and pinion, gears, clutches, and carrier are subjected to 100% inspection. Additionally, all bearings, seals, crush sleeves, pinion nuts, and shims are replaced with new parts. The housings are cleaned using a state-of-the-art hydro blasting and rinsing process to restore them to an OEM finish. Correct rolling torque is established using precise inch-pound measurements for optimal setup and durability. This product is built to order and includes a refundable core charge. Please confirm and accept the core charge of +$1,000, which will be returned upon receipt of your old, salvageable part. Zumbrota Drivetrain has been serving customers for over 30 years, offering options like same-day dispatch, free shipping over $199, and expedited shipping at checkout.
