Product Description

The Revolution Gear & Axle REV-JK-RUB-513 gear package is engineered specifically for 2007-2018 Jeep Wrangler JK Rubicon models equipped with Dana 44 front and Dana 44 rear axles. With a 5.13:1 ratio, this kit delivers improved drivetrain responsiveness, better performance with larger tires or lifts, and maintains reliable service in demanding off-road or heavy-load situations.

Constructed from high-grade 8620 alloy steel and heat-treated to ensure durability, the ring & pinion gear sets are precision-lapped for smooth operation and long life under load. This full-kit solution includes both front and rear gear sets plus master install bearing kits, making it ideal for JK Rubicon owners seeking a comprehensive gearing upgrade.

Installation should be performed by a qualified technician using proper differential-setup tools: bearing preload, backlash, and gear-pattern must be correctly set for optimal performance and longevity. Fitment is confirmed for the years and model listed; coverage for other years, other axle configurations, or different vehicle platforms is unconfirmed at time of listing.
