Product Description

The Revolution Gear & Axle REV-JL-220/210-488DC gear package is engineered for 2018-2025 Jeep Wrangler JL and Jeep Gladiator JT models equipped with the 220 mm front and 210 mm rear Dana 44 axles. With a 4.88:1 ratio and premium 2-Cut gear manufacturing, this kit provides serious low-end torque, improved driveline responsiveness, and is ideal for large-tire builds, lifted suspensions or heavy-use off-road/overlanding setups.

Constructed from premium 8620 alloy steel and heat-treated to rigorous standards, the ring & pinion gear sets are precision-lapped for smooth operation, long service life and minimal noise under heavy load. The full kit includes both front and rear gear sets plus master install bearing kits - making it a comprehensive upgrade rather than a simple ring & pinion swap.

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 models listed above; coverage for other years, axle configurations or vehicle platforms is **unconfirmed at time of listing**.
