Revolution Gear & Axle Ring & Pinion Set for Jeep (2007-18) Wrangler JK, Dana 44 Rear Axle (4.10 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 4.10 ratio. It is the gear set on its own, a common choice for restoring performance after a tire upgrade.

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, and fits both Rubicon and non-Rubicon JK rear Dana 44 housings. Confirm that your carrier suits a 4.10 ratio before installing.

A 4.10 is a well-balanced regear for JK owners running larger tires who want back the throttle response, low-speed control and towing grunt the bigger meats took away.

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 strong way to regear the JK rear Dana 44 for a big-tire build.
