Description

The Yukon Gear YDAT8-529SPL is a complete, fully assembled dropout differential, expertly built and ready for installation. Designed for Toyota 8-inch front differentials, this unit comes pre-shimmed and backlashed to spec, simplifying the installation process. The assembly is upgraded with a robust Yukon steel spool, ensuring maximum traction and performance for demanding applications. Constructed with a nodular iron case, this differential offers improved rigidity and superior power handling capabilities. This design reduces deflection, leading to consistent gear contact and extended service life. The assembly includes a pinion yoke and features a 5.29 gear ratio with a 30 spline count, making it a high-performance upgrade for your Toyota's drivetrain. Key specifications include a 1.785-inch journal size for the spool and a nodular iron case material. The product is sold as a complete dropout unit, ready to be installed into your existing differential housing, requiring only the addition of fluid and a diff cover. This part is specifically designed for Toyota 8-inch front differentials with 30 spline full spools.
