Description

This EXCEL ring and pinion gear set provides a 3.55 ratio for the robust Ford 10.25-inch rear differential. It is a direct replacement for the original gears in 1993-1998 Ford F-250, F-350, and F-Super Duty trucks. The 3.55 ratio offers a good balance between fuel economy on the highway and strong pulling power for towing or hauling heavy loads, often serving as an upgrade from numerically higher gears (e.g., 4.10) for more highway-oriented driving.
