Product Description

This Revolution Gear & Axle D44-M220-513DC ring & pinion set is engineered for the rear Dana 44/M220 axle found in the 2018+ Jeep Wrangler JL and 2020+ Jeep Gladiator JT. With a 5.13:1 gear ratio and precision 2-Cut (face-hobbing) construction, this set delivers enhanced wheel torque, making it ideal for larger tire setups, off-road use, or heavier load/towing applications while maintaining efficient engine RPM.

Manufactured from premium heat-treated 8620 alloy steel and machined to exact tolerances, the D44-M220-513DC provides quiet, long-lasting performance under demanding conditions. Whether building your trail rig, upgrading your tires, or enhancing your drivetrain, this gear set offers a reliable upgrade path.

Installation requires correct setup: proper preload, backlash and pattern must be established. This gear set fits the rear differential only; pairing with matching front gears is strongly recommended for drivetrain harmony. Fitment confirmed through 2024; 2025 vehicle coverage is unverified. Always verify your exact axle model (Dana 44 / M220), vehicle trim, engine and drivetrain before purchase.
