Product Description

The Revolution Gear & Axle D44-M220-456DC ring & pinion set is tailored for the rear Dana 44/M220 axle found in the 2018+ Jeep Wrangler JL, 2020+ Jeep Gladiator JT and 2021+ Ford Bronco. With a 4.56:1 ratio and precision 2-Cut face-hobbing manufacturing, this gear set restores lost torque when upgrading to larger tires, carrying heavier cargo or tackling tougher trails.

Crafted from heat-treated 8620 alloy steel and machined to exacting tolerances, the D44-M220-456DC delivers quiet, durable performance. Ideal for off-road builds, lifted rigs or any application where drivetrain strength and optimized gearing matters.

Installation requires proper setting of preload, backlash and gear pattern. This set fits the rear differential only, and pairing with matched front gears is strongly recommended for best drivetrain harmony. Fitment confirmed through 2024; 2025 vehicle coverage is unconfirmed. Always verify your Dana 44 / M220 rear axle model before purchase.
