Product Description

The Revolution Gear & Axle D44-373 ring and pinion set is engineered for vehicles with Dana 44 standard-rotation rear differentials. Featuring a 3.73:1 ratio, this gear set improves torque delivery, drivetrain efficiency, and off-road performance, especially when using oversized tires or handling heavy loads. Constructed from heat-treated 8620 steel with a robust 8.5-inch ring gear and 26-spline pinion, it offers long-lasting durability and smooth engagement.

Designed for Jeeps and other off-road vehicles with Dana 44 rear axles, this gear set enhances performance while maintaining highway drivability. Correct installation is critical, requiring proper verification of axle code, spline count, rotation, preload, backlash, and gear pattern. Ring gear bolts and bearings are not included in this package unless otherwise specified, so confirm the complete package contents before installation.
