Product Description

The Revolution Gear & Axle REV-JK-NON-513 gear package is engineered for the 2007-2018 Jeep Wrangler JK Non-Rubicon models equipped with Dana 30 front and Dana 44 rear axles. With a 5.13:1 ratio, this kit delivers stronger torque, better performance with larger tires and hostile terrain, and improved overall drivability when factory gearing falls short.

Built from high-grade 8620 alloy steel and precision-heat-treated, the ring & pinion gears are lapped for quiet, smooth operation and long life. The inclusion of full front and rear differential sets plus master install kits make this a true full-kit solution rather than just a ring & pinion swap. Ideal for lifted JKs, heavily modified builds or trail rigs requiring reliable gearing upgrades.

Installation should be done by a qualified technician using proper differential setup tools - including bearing preload, backlash and correct gear pattern. While this kit is engineered for direct installation in verified JK Non-Rubicon housing configurations, always verify your axle housings, spline counts and differential type. Fitment is confirmed for the years and models listed; coverage for other years or axle variants is unconfirmed at time of listing.
