  Ring & Pinion, Gear And Pinion Assembly Driving

• Description:

  This is the genuine Ford differential ring and pinion set, the matched gear pair that transfers driveline torque from the driveshaft to the axle shafts and sets the final drive ratio for the vehicle. Cataloged by Ford as a ring and pinion, it meshes the pinion gear with the ring gear to turn the drive torque ninety degrees and multiply it through the axle, delivering the correct gear ratio for the truck's capability. It fits the 23-25 F-350 Super Duty in the applicable rear axle configuration. Owners look for this gear set when the axle whines, howls, or growls under acceleration or coast, when there is chipped or spalled gear damage, or when a rebuild or ratio change requires new matched gears. Because the ring and pinion carry the full driveline load, they can wear or fail from high mileage, low lubricant, overloading, or a prior setup error. A damaged gear set produces noise, driveline vibration, and eventual failure if not addressed. As a genuine Ford part it is manufactured and lapped to the original specification so it meshes correctly when set up to Ford's pattern and backlash requirements. Installing the correct matched set restores quiet, reliable power transfer. Confirm the axle, ratio, and configuration against your vehicle before ordering, and note that proper setup is required.

• Applications: 11.80, 12.40 REAR AXLE.
