Revolution Gear & Axle Ring & Pinion Set for Ford 10.25" Rear Axle (5.38 Ratio, Long Pinion)

This Revolution Gear & Axle ring and pinion is built for the Ford 10.25 inch rear axle in a 5.38 ratio with a long-pinion design. It is the gear set on its own, suited to heavy trucks and big-tire builds.

The set uses a 31-spline pinion and a 10.25 inch ring gear in 8620 alloy steel with a 12-bolt cover pattern, cut and heat treated to meet or exceed original equipment standards. This gear family has no carrier break, which keeps carrier selection straightforward.

A 5.38 is a deep ratio for owners running large tires or doing heavy towing and off-road work who want maximum torque multiplication at the wheels. The Ford 10.25 inch is a stout full-size truck axle that responds well to a proper regear.

This is a gear set only. Setup bearings, crush sleeve, shims and pinion seal are sold separately, and no carrier or locker is included. Pair it with a Revolution Ford 10.25 inch master install kit and have a qualified installer set pinion depth, backlash and preload.

Backed by a 2-year warranty against manufacturing defects, this long-pinion 5.38 set is a strong upgrade for regearing a Ford 10.25 inch rear axle.
