Revolution Gear & Axle Ring & Pinion Set for Jeep (2007-18) Wrangler JK Rubicon, Dana 44 Front Axle (4.56 Ratio)

This Revolution Gear & Axle ring and pinion set is built for the front Dana 44 in 2007-18 Jeep Wrangler JK Rubicon models, cut in a 4.56 ratio with reverse rotation to match the Rubicon's high-pinion front housing.

The gears use a 24-spline pinion, an 8.5" ring gear, and heat-treated 8620 steel. The carrier break is 3.73 and down, so this 4.56 set is designed to work with the deeper-ratio carrier. To keep the front and rear axles turning the same effective ratio, run a matching 4.56 set in the Dana 44 rear.

A 4.56 re-gear is one of the most common upgrades on a JK Rubicon after moving to larger tires. The taller rubber raises your effective gearing and dulls throttle response and crawl ratio; 4.56s bring that torque back at the wheels for trail and daily driving alike.

This is a gear set only. It does not include bearings, shims, a crush sleeve, a pinion seal, or a locker – those are sold separately. Confirm you have the JK Rubicon front Dana 44 with reverse rotation and a compatible carrier before ordering. Gear setup is precision work, so professional installation is strongly recommended.

Pair this set with a Revolution Dana 44 JK front master install kit and a matching rear gear set for a balanced, quiet re-gear backed by a 2-year warranty against manufacturing defects.
