Keep your Ford 8.8" rear axle running true with the American Axle & Manufacturing F88355GS ring and pinion set. Engineered as a matched 3.55 ratio set with a 39-tooth ring gear and 11-tooth pinion, this Premium-grade component is designed specifically for the 8.8-inch 10-bolt rear axle found across a broad range of Ford, Lincoln, Mercury, and Mazda vehicles spanning model years 2001 through 2023, including F-150, Mustang, Explorer, Ranger, Crown Victoria, and more. With a 10-bolt ring gear pattern and 30-spline pinion, this set is built to restore proper gear mesh and axle function for a replacement or gear-ratio change.

Backed by AAM's limited one-year warranty, this set is ready to install as new (PRC: NEW) and ships as a single application-ready unit.
