Yukon Gear High Performance Thick Gear Set For 10.5in GM 14 Bolt Truck in a 5.13 Ratio

This product is a Yukon Gear & Axle high-performance thick ring and pinion gear set, designed for GM 10.5-inch 14-bolt truck axles with a 5.13 gear ratio. This set includes the ring gear and pinion gear, which work together to change the rotational speed from the driveshaft to the wheels. It's a solid option for trucks like the Chevrolet Express 2500 or Silverado 2500 HD that have had their gearing changed to accommodate larger tires or increased engine power.

Yukon engineers use high-grade steel for both the ring and pinion gears, and the tooth surface finish is designed to reduce friction and heat. This construction helps ensure durability, especially under high torque conditions or during extended use. The 'thick' designation means these gears are designed to fit carriers that originally came with 4.10 or numerically lower gear ratios, ensuring proper mesh and function within the differential housing.

Choosing the right gear ratio is key to getting the most out of your truck's drivetrain. A 5.13 ratio is a significant change from stock and is typically chosen when you've upgraded to much larger tires, helping to bring your engine's RPMs back into an optimal range for driving and towing.
