Product Description

The Revolution Gear & Axle REV-JL-220/210-456DC gear package is engineered for 2018-2025 Jeep Wrangler JL and Jeep Gladiator JT models equipped with the 220 mm/210 mm Dana 44 axle housings. With the 4.56:1 ratio and premium 2-Cut gear construction, this kit provides improved low-end performance, better large-tire response and greater driveline flexibility for lifted or heavy-use builds.

Constructed from high-grade 8620 alloy steel and precision-heat-treated, the gear sets offer smooth, quiet operation and long service life under demanding conditions. The full kit includes both front and rear gear sets with master bearing install kits - giving you a complete solution for a full axle gearing upgrade without replacing the housing.

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