Product Description

The Revolution Gear & Axle D44-M220-488DC ring & pinion set is tailored for the rear Dana 44/M220 axle found on the 2018+ Jeep Wrangler JL and 2020+ Jeep Gladiator JT. With a 4.88:1 gear ratio and a 2-Cut (face-hobbing) manufacturing process, this gear set provides stronger torque output, smoother drivetrain response and better compatibility with larger tires or off-road modifications.

Crafted from high-strength 8620 heat-treated alloy steel and built to precise tolerances, the D44-M220-488DC offers excellent durability, quiet operation and reliable performance under demanding conditions. Whether you're upgrading for trail use, towing or simply better performance with bigger tires, this gear set is engineered for the job.

Installation requires proper setup of backlash, preload and gear pattern. The set fits the rear differential only, and matching front gears are recommended for optimal drivetrain harmony. Fitment is confirmed through 2024; 2025 vehicle coverage is not fully verified. Always confirm your exact axle model (Dana 44 / M220) and drivetrain before purchase.
