Product Description

This Revolution Gear & Axle D44-M210-488RDC ring & pinion set is engineered for the front Dana 44/M210 axle found on the 2018+ Jeep Wrangler JL and 2020+ Jeep Gladiator JT. The 4.88:1 ratio is ideally suited for vehicles with larger tires, off-road rigs, or heavier loads where improved torque is required. It ensures the engine runs more efficiently by keeping RPMs at a more optimal level while increasing wheel torque.

Constructed from heat-treated 8620 alloy steel and manufactured with a high-precision 2-Cut gear process, this set delivers enhanced durability, quieter gear operation and stronger performance for demanding use. It's a solid upgrade for off-road enthusiasts, trail runners, or those modifying their JL/JT for bigger tires and more aggressive setups.

Installation demands proper setup of backlash, preload and gear pattern - it's recommended to upgrade in matched sets and verify axle configuration (Dana 44 / M210) before ordering. Fitment is confirmed through 2024; 2025 vehicle coverage is currently unconfirmed. Always verify your exact axle model before purchase.
