Revolution Gear & Axle Gear Package for Jeep (2007-18) Wrangler JK Rubicon, Dana 44 Front & Rear (4.88 Ratio, Timken Bearings)

This is a complete Revolution Gear and Axle gear package for the 2007-18 Jeep Wrangler JK Rubicon, which runs a Dana 44 front and a Dana 44 rear. It bundles both ring and pinion sets in a matched 4.88 ratio with the correct master install kits.

The package includes front and rear ring and pinion gear sets plus mating master install kits with Timken bearings. The rear Dana 44 uses a 24-spline pinion and the front Dana 44 is a 24-spline reverse-cut design, both correct for the JK Rubicon axles. Gears are 8620 steel, heat treated to OE-level standards.

A 4.88 ratio is one of the most popular re-gears for JK Rubicons running 35s and 37s, restoring acceleration and crawl while keeping highway driving comfortable. Because it is a verified, matched package, you avoid the risk of mismatched ratios or the wrong bearing kit.

Note what is not included: the package does not come with axle shafts or a locker. The JK Rubicon already has factory front and rear lockers, so this is purely the gears and bearings. Gear setup is precision work and should be done by an experienced installer.

For a JK Rubicon that needs deeper gears for bigger tires, this matched 4.88 package is the straightforward, OE-quality way to re-gear both axles at once.
