Rugged Ridge D44513RJK ALLOY USA RING & PINION GEAR SET, DANA 44, FRONT, 5.13

The Rugged Ridge D44513RJK refers to a ring and pinion gear set designed for the Dana 44 front axle on Jeep Wrangler JK models, typically with a 5.13:1 gear ratio. These gear sets replace the stock differential gears to help optimize torque delivery and drivability—especially useful when larger tires or heavier loads are used, as a higher gear ratio can improve acceleration and throttle response by keeping the engine in a more effective power band. While branded in some listings as Rugged Ridge, this part is often supplied by Alloy USA and includes precision-engineered, high-strength 8620 steel gears manufactured with modern gear-cutting processes for durability and performance. The D44513RJK set is matched to the front Dana 44 axle on 2007–2018 Wrangler JK/JKU vehicles and is sold as a gear pair without installation hardware.
