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

This is a Revolution Gear & Axle ring and pinion set for the Dana 60 reverse-rotation (high-pinion / front) axle in a 5.38 ratio, cut as a thick gear. It's identified by axle rather than a single vehicle and is a common choice for 1-ton front ends and heavy-duty swaps. This listing is the case-quantity MPN of the standard D60-538RT thick reverse gear set.

The thick ring gear is the key feature: it allows a deep 5.38 ratio to bolt onto a 4.10-and-numerically-lower carrier without switching carriers, saving cost on big re-gears. The pinion is 29-spline, the ring gear is 9.75", the ring gear bolt thread is 1/2", and the gears are made from heat-treated 8620 steel. The carrier break is 4.10/4.56.

A 5.38 set is aimed at rigs running tall tires in the 40-inch class, where you need a numerically deep gear to keep crawl ratio and on-road drivability. Reverse-rotation cut means this is for the front (high-pinion) side of a matched front-and-rear gear setup, 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. Verify you have a reverse-rotation Dana 60 and a carrier compatible with the thick gear (4.10 and numerically lower) before ordering. Gear setup is precision work, so professional installation is strongly recommended.

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