Revolution Gear & Axle Ring & Pinion Set for Dana 60 Reverse Rotation (5.38 Ratio, Thick)

This Revolution Gear & Axle ring and pinion set fits the Dana 60 reverse-rotation (high-pinion / front) axle in a 5.38 ratio and is cut as a thick gear. It's identified by axle rather than a single vehicle and is a go-to for 1-ton front ends and heavy-duty axle swaps.

The thick ring gear is what makes this set valuable: it lets a deep 5.38 ratio bolt to a 4.10-and-numerically-lower carrier without a carrier change. The pinion is 29-spline, the ring gear is 9.75", the ring gear bolt thread is 1/2", and the gears are heat-treated 8620 steel. The carrier break is 4.10/4.56.

A 5.38 ratio targets rigs on tall tires in the 40-inch class that need a numerically deep gear to keep their crawl ratio and highway drivability. The reverse-rotation cut means this is the front (high-pinion) half of a matched front-and-rear gear package, or a standalone front Dana 60.

This is a gear set only. It does not include bearings, a crush sleeve, shims, a pinion seal, or a locker – those are sold separately. Confirm a reverse-rotation Dana 60 and a thick-gear-compatible carrier (4.10 and numerically lower) before ordering. Because gear setup is precision work, professional installation is strongly recommended.

Pair it with a Revolution Dana 60 master install kit and a matching standard-rotation rear set for a balanced 5.38 build, backed by a 2-year warranty against manufacturing defects.
