Product Description

The Revolution Gear & Axle REV-JL-200/186-488 gear package is engineered for the 2018-2025 Jeep Wrangler JL Non-Rubicon models fitted with the Dana 30 (200 mm) front and Dana 35 (186 mm) rear axles. With the 4.88:1 ratio, this kit restores torque and driveline efficiency when larger tires, lifted suspensions or heavier loads have exceeded factory gearing limits.

Constructed from premium 8620 alloy steel and heat-treated to OEM-level standards, the included ring & pinion sets are precision-lapped for smooth operation and longevity. The full kit includes both front and rear gear sets plus master install kits, making it a comprehensive solution for Wrangler JL owners upgrading drivetrain gears without replacing axles.

Installation should be done by a qualified technician using the correct differential-setup tools - bearing preload, backlash, and gear pattern must be properly set for optimal performance and longevity. Fitment is confirmed for the years and model listed; coverage for other cars, axle configurations or model years outside 2018-2025 is unconfirmed at the time of listing.
