What is the benefit of a 4.56 gear ratio?

A 4.56 gear ratio typically improves acceleration and towing performance compared to stock gearing. It's often chosen by drivers who have installed larger tires or increased engine power, as it helps bring the engine's RPMs back into a more effective range for those modifications.

The Y.E.S. Plan is an optional, lifetime protection plan offered by Yukon Gear & Axle. It provides comprehensive coverage for your gear set for as long as you own the vehicle, offering peace of mind beyond the standard 1-year warranty against manufacturing defects.

Product Details

Yukon Gear & Axle is well-known for making solid drivetrain components, and their high-performance ring and pinion sets are no exception. This particular set is designed for GM 12-bolt truck axles and comes in a 4.56 ratio, which is a popular choice for owners who have upgraded to larger tires or added significant horsepower and want to bring their gearing back into an optimal range for acceleration and towing. It fits a wide variety of Chevrolet and GMC trucks and SUVs from the mid-60s through the mid-80s, including models like the Chevrolet C10 Pickup and GMC K15 Pickup.

These gears are built with high-grade steel and feature a specific tooth surface finish that Yukon engineers developed to reduce friction and heat. This design helps ensure longevity, especially under high torque conditions or during extended use. The fitment is designed to OEM specifications, meaning you can expect a direct replacement for your stock gears when installed correctly. Yukon also backs these sets with a 1-year warranty against manufacturing defects, and they offer an optional Y.E.S. Plan for lifetime coverage.
