Ford F-250 2017-22 4.30-5.38 Ratio F10.5-D60SR Koyo Bearing Gear Package

The Complete Regear Solution for Your F-250.

The 2017-2022 Ford F-250 is a towing powerhouse but adding 37-inch or 40-inch tires drastically changes the effective gear ratio. This puts unnecessary strain on your transmission and engine, resulting in sluggish acceleration and high transmission temperatures when pulling a grade. Revolution Gear & Axle provides the ultimate fix with this complete, matched gear package.

At Overland Truck Store, we emphasize quality components for heavy-duty trucks. That is why we selected this specific package featuring Koyo Bearings. When you are hauling a camper or towing a toy hauler, you need the reliability of premium Japanese bearings, not cheap generic alternatives. This kit ensures your differentials run cool and quiet, mile after mile.

This "Master" package includes everything needed to regear both axles. It features the massive Dana 60 front gears and the legendary Ford Sterling 10.5-inch rear gears. Whether you choose 4.88s for a daily driver on 37s or 5.38s for a dedicated tow rig on 40s, this setup restores the mechanical advantage your truck was built to have.

Installer Note: Critical Axle Identification Required. While most F-250s come with the Sterling 10.5" rear axle, some Heavy Duty Tow Package models may come with the Dana M275. This kit is ONLY for the Sterling 10.5" (identifiable by 12 diff cover bolts). If your rear axle has 14 cover bolts (Dana M275), this kit will not fit. Please visually verify before ordering.
