10.5-Inch Axle Assembly 4.10 Ratio Posi Limited-Slip

The Zumbrota Drivetrain RAA435-2246E-P is a remanufactured complete axle assembly specifically engineered for 2005-2007 Ford F250 and F350 models equipped with the 10.5-inch axle and a 4.10 gear ratio with a Posi limited-slip differential. Each axle assembly is built to order and undergoes a comprehensive remanufacturing process to ensure quality and durability. This includes straightening tubes to OEM specifications, testing housings for wear and cracks, and performing a 100% inspection of all internal parts such as ring and pinion gears, internal gears, clutches, and carriers. To guarantee optimal performance and longevity, all bearings, seals, crush sleeves, pinion nuts, and shims are replaced. The housings are then restored to an OEM finish through a state-of-the-art hydro blasting and rinsing process, and precise rolling torque is established using inch-pound measurements. This remanufactured axle assembly includes a refundable core charge, which is a deposit returned upon the receipt of your old, salvageable part. Detailed core return instructions are available. The product is built to order and ships when ready, with options for expedited shipping available at checkout.
