The Yukon Gear & Axle YG F10.5-456-37 is a high-performance ring and pinion gear set engineered for the Ford 10.5-inch differential found on 2011 and newer trucks. Featuring a 4.56 gear ratio and 37-spline pinion, this gear set is purpose-built to restore and enhance drivetrain performance when running larger tires, increased horsepower, or demanding tow and haul applications.

Key Features:

• 4.56 gear ratio optimizes torque output and acceleration, especially when paired with oversized tires or upgraded powertrains
• 37-spline pinion shaft for increased torque capacity and strength
• Engineered to OEM fitment specifications for the Ford 10.5-inch differential (2011 and up)
• High-grade steel construction on both ring and pinion for superior strength and long service life
• Advanced gear tooth surface finish reduces friction and heat under high-torque and high-load conditions
• State-of-the-art heat-treating process ensures maximum wear resistance and dimensional accuracy
• Manufactured using leading-edge design and testing processes, backed by two in-house quality labs
• Backed by Yukon's Y.E.S. (Yukon Elite Service) Plan — a lifetime, no-questions-asked protection plan for as long as you own your vehicle
