Revolution Gear & Axle Ring & Pinion Set for Jeep (2007-18) Wrangler JK, Dana 44 Rear Axle (3.73 Ratio)

This Revolution Gear & Axle ring and pinion set is made for the rear Dana 44 in 2007-18 Jeep Wrangler JK models, in a 3.73 ratio. It is the gear set on its own, intended as an OE-style replacement or a mild ratio change.

The set uses a 24-spline pinion and an 8.5 inch ring gear in 8620 alloy steel, cut and heat treated to meet or exceed original equipment standards. The JK rear Dana 44 carrier break is 3.73 and down, so this 3.73 set fits the lower carrier – confirm what your axle currently runs before ordering.

A 3.73 works for JK owners staying near stock tire sizes who want to recover a bit of throttle response and towing grunt without a dramatic RPM change. Owners running larger tires generally step to a numerically higher ratio.

This is a gear set only. Setup bearings, crush sleeve, shims and the pinion seal are sold separately, and no carrier or locker is included. Pair it with a Revolution JK Dana 44 master install kit and have a qualified installer set pinion depth, backlash and preload.

Covered by a 2-year warranty against manufacturing defects, this gear set is a dependable choice for refreshing or regearing the JK rear Dana 44.
