Show original supplier description
The Yukon Grizzly Locker YGLD50-30 is a robust mechanical locking differential engineered for Dana Spicer 50 axles featuring 30 splines. It offers a solution for increased traction and performance in demanding off-road conditions. The differential is constructed with a forged case and high-strength 8620 internals, designed to withstand significant torque and stress. Yukon has implemented a patented internal design intended to mitigate common failure points found in other lockers, enhancing reliability. This locker is assembled in the USA, ensuring quality control. It is designed to provide 100% power to both wheels when engaged, offering superior traction for rock crawling, trail running, and off-road racing. This locker is specifically designed for the Dana 50 axle with 30 splines. While specific vehicle fitment requires selection, it is compatible with applications using the Dana 50 30-spline axle, such as certain Ford Excursion models from 2000-2005 with the 5.4L engine and straight axle configurations.
