  Differential Assembly, Differential Carrier

• Description:

  This is the genuine Ford differential assembly, also cataloged as a differential case or differential carrier, for 2023-2025 Super Duty trucks running the heavy 11.80 inch rear axle. Ford's catalog describes it as the loaded limited slip unit for F-450 Super Duty with the 11.80 axle and for F-550 Super Duty, with ring gear callouts of 11.80 inch and 12.40 inch listed against those bodies. The differential carrier holds the side gears, pinion gears and the limited slip clutch pack, splitting torque between the rear wheels while allowing them to turn at different speeds through a corner, and the clutch pack transfers torque to the wheel that still has grip when the other side is on ice, mud or gravel. Trucks that need this part typically show chatter or banging in tight turns, a clunk on throttle transitions, one wheel spinning freely with no bite on a slick launch, or gear and bearing damage found on teardown after metal shows up on the drain plug. Because ring gear diameter and ratio vary across the heavy chassis lineup, confirm the axle tag before ordering. Set carrier bearing preload and backlash to Ford specification and break the new limited slip in with the correct friction modifier.

• Applications: 11.80, 12.40 REAR AXLE.
