Description

The Yukon Gear and Axle YG T8-456K is a high-performance Ring & Pinion gear set engineered for Toyota 8-inch differentials, offering a 4.56 gear ratio. The kit comes complete with a 29-spline pinion gear set, a matching 29-spline conversion yoke, pinion seal, and pinion nut, providing all the necessary components for installation. The gear ratio change to 4.56 is particularly beneficial for vehicles equipped with larger tires, helping to restore optimal engine RPM and improve acceleration. This specific gear set is designed to fit 1979-1985 Toyota Pickup and 4Runner models, along with 1975-1990 Landcruiser vehicles. Ensure your vehicle falls within these specified model years for proper fitment.
