Product Details

If you're looking to re-gear your Dana 80 differential, this Yukon Gear & Axle high-performance ring and pinion set is a solid option. It comes with a 5.13 ratio, which is ideal for optimizing your vehicle's performance when you've upgraded to larger tires or added significant horsepower. This set is designed to fit a wide range of heavy-duty trucks and vans, including popular models like the Ford F-350 Super Duty, Chevrolet C3500, and Dodge Ram 2500. By changing your gear ratio, you can improve your vehicle's acceleration and bring your speedometer back to accurate readings after tire upgrades.

Yukon engineers focus on quality, using high-grade steel for both the ring and pinion gears. They pay close attention to the tooth surface finish, which is designed to reduce friction and heat buildup. This is especially important for high-torque conditions and extended use, helping to ensure longevity. The fitment is designed to OEM specifications, meaning it should integrate smoothly into your existing differential housing. Yukon also backs these gear sets with a 1-year warranty against manufacturing defects, and offers an optional Y.E.S. Plan for lifetime coverage.

This set includes the ring and pinion gears. Remember that re-gearing a differential is a complex job that requires specialized tools and knowledge. It's highly recommended to consult the manufacturer's installation instructions or have a qualified mechanic perform the installation to ensure proper setup and performance.
