Product Details

Yukon Gear & Axle has built a strong reputation for making solid drivetrain components, and their high-performance ring and pinion sets are a prime example. If you're looking to change the gearing in your Dana 70 axle, this 4.56 ratio set is designed to handle the demands of increased horsepower and larger tires. Yukon engineers focus on creating gear teeth with a surface finish that helps reduce friction and heat, which is crucial for long-term durability under high torque conditions.

This set is made from high-grade steel and is designed to fit OEM specifications, meaning it should install cleanly into your Dana 70 axle housing. The 4.56 ratio is a popular choice for those who have upgraded to larger tires or added significant power, as it helps bring the engine's RPM range back into its optimal operating zone for better acceleration and towing capability. With a 10.50-inch ring gear diameter and a 29-spline pinion, this set is built for heavy-duty applications found in many Chevrolet and Dodge trucks and vans from the 1970s through the early 2000s.

Beyond the gear set itself, Yukon offers a 1-year warranty against manufacturing defects, and for even greater peace of mind, they provide the Y.E.S. Plan, a lifetime protection plan that covers your gears as long as you own the vehicle. This comprehensive coverage underscores Yukon's confidence in the quality and longevity of their products.
