Description

The Yukon Dropout Assembly is a fully assembled, ready-to-install differential unit engineered for Toyota 8-inch rear differentials. This dropout assembly is manufactured by Yukon Gear and Axle, ensuring quality and reliability for your drivetrain. This assembly boasts a 4.56 gear ratio, which is ideal for applications requiring improved acceleration and towing capacity compared to stock ratios, especially when paired with larger tires. It features 30 spline count, a common specification for many Toyota rear axles. The unit comes complete and includes the essential yoke, meaning all major components are provided for a comprehensive upgrade or replacement. It is important to verify fitment with your specific Toyota model's 8-inch rear differential. While detailed fitment data is not explicitly provided, the product lists its compatibility with Toyota 8-inch rear differentials, 30 spline count, and includes a yoke. Always confirm compatibility with your vehicle's existing setup before purchase.
