Product Details

Yukon Gear & Axle has built a solid reputation for making dependable drivetrain components, and their high-performance ring and pinion sets are a prime example. If you're looking to change your vehicle's gearing for better performance with larger tires or more horsepower, this set offers a 3.73 ratio designed for GM 8-inch differentials. This ratio is a popular choice for balancing everyday drivability with improved acceleration and towing capability.

These gears are constructed from high-grade steel, and Yukon engineers pay close attention to the tooth surface finish. This design helps reduce friction and heat buildup, which is crucial for longevity, especially under demanding conditions like high torque situations or extended use. The fitment is designed to OEM specifications, meaning it should integrate smoothly into your existing differential housing. The ring gear diameter is 8 inches, and it uses 10 ring gear bolts, with a 27-spline pinion.

This gear set is suitable for a range of GM vehicles, including models like the Chevrolet Colorado, GMC Canyon, and Hummer H3. Yukon also backs their products with a 1-year warranty against manufacturing defects, and they offer an optional lifetime Y.E.S. Plan for comprehensive protection. When installing a new gear set, it's important to follow the manufacturer's break-in procedure to ensure proper seating and longevity.
