What is the benefit of a 3.73 gear ratio?

A 3.73 gear ratio is often a good compromise for vehicles that have been fitted with larger tires. It helps to bring your speedometer back to accurate readings and improves low-end torque for better acceleration and towing capability compared to taller (numerically lower) gear ratios.

What else is needed to install this gear set?

Installing a ring and pinion gear set requires a comprehensive installation kit. This typically includes new bearings, races, seals, shims, and gear marking compound. These items are sold separately and are crucial for proper gear setup and longevity.

What kind of warranty does this gear set come with?

Yukon Gear & Axle provides a 1-year warranty against manufacturing defects on this ring and pinion gear set. They also offer an optional Y.E.S. Plan for lifetime coverage, which provides comprehensive protection for your gears as long as you own the vehicle.

Product Details

If you're looking to re-gear your heavy-duty truck or van for larger tires or more power, a new ring and pinion set is a critical component. This high-performance gear set from Yukon Gear & Axle is designed for the Dana 70 axle, featuring a 3.73 ratio. This ratio is often chosen to bring your speedometer back into calibration after installing larger tires, or to improve towing and hauling performance by giving you more torque multiplication off the line.

Yukon engineers use advanced heat-treating techniques and rigorous testing to ensure these gears meet exacting standards. They're made from high-grade steel, and the tooth surface finish is designed to reduce friction and heat buildup. This means they can handle high torque conditions and extended use, whether you're on the trail or on the job. The fitment is designed to OEM specifications, making installation as straightforward as possible, though a professional installation is recommended for this type of component.

This gear set is a solid option for a wide range of Chevrolet and Dodge trucks and vans equipped with the Dana 70 axle. Yukon Gear & Axle also backs this set with a 1-year warranty against manufacturing defects, and they offer an optional Y.E.S. Plan for lifetime coverage. Remember that a complete gear installation kit, including bearings, seals, and gear marking compound, is typically required for this job and is sold separately.
