What is the purpose of changing the gear ratio?

Changing your gear ratio affects how your vehicle's engine power is delivered to the wheels. A 3.73 ratio, like in this set, is often chosen to improve acceleration and towing capacity, especially when larger tires are installed, by allowing the engine to reach higher RPMs more easily for a given road speed.

Does this gear set come with installation hardware?

This product is a ring and pinion gear set. Installation typically requires additional components such as bearings, seals, and shims, which are usually sold separately. Always consult your vehicle's service manual for a complete list of parts needed for a differential gear change.

What kind of warranty does Yukon Gear & Axle offer?

Yukon Gear & Axle offers a 1-year warranty against manufacturing defects on their high-performance gear sets. They also offer an optional Y.E.S. Plan for lifetime, comprehensive protection.

Product Details

If you're looking to change the gear ratio in your GM 10.5-inch 14-bolt truck differential, this Yukon Gear & Axle high-performance ring and pinion set is a solid option. This set is designed for a 3.73 ratio, which is a popular choice for balancing towing capability and highway cruising, especially if you've upgraded to larger tires. It fits a wide range of GM trucks and SUVs, including models like the Chevrolet Avalanche 2500, C2500 Suburban, and Express 2500.

Yukon engineers focus on quality, using high-grade steel for both the ring and pinion gears. They've also paid attention to the gear tooth surface finish, which helps reduce friction and heat. This means your gears can handle more torque and run cooler, which is important for high-horsepower applications or heavy towing. The fitment is designed to OEM specifications, meaning it should install without major modifications on compatible axles.

When you're ready to tackle this kind of internal differential work, make sure you have the right tools and a service manual for your specific vehicle. Re-gearing a differential is a job that requires precision and attention to detail to ensure proper backlash and gear pattern.
