Product Description

The Revolution Gear & Axle REV-JL-220/186-456 gear package is engineered for 2018-2025 Jeep Wrangler JL Non-Rubicon models fitted with the 220 mm front and 186 mm rear axle housings. With a 4.56:1 ratio, this kit improves driveline responsiveness, supports larger tires or lift kits, and enhances engine efficiency under heavier loads or off-road use.

Constructed from high-grade 8620 alloy steel, fully heat-treated, and precision-lapped, the ring & pinion gears provide smooth engagement, long service life and reduced noise. The full front and rear gear sets plus master install bearing kits make this a complete upgrade kit - ideal for JL Non-Rubicon owners who are upgrading tires, gearing or drivetrain components.

Installation should be carried out by a qualified technician using the correct 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 axle combination listed; coverage for other years, axle configurations or vehicle models is unconfirmed at the time of listing.
