BG Ultra-Guard® is a revolutionary multi-purpose synthetic gear oil compatible with all car and truck applications calling for GL-5 gear oil. It provides superior thermal stability, smoother gear shifting, optimum drive line efficiency, quieter operation, protection against wear, pitting, and corrosion, seal compatibility and improved seal performance.

The hypoid gear set design demands that a high level of extreme pressure additive be utilized for long life performance of the ring gear and pinion. The high level of extreme pressure additive in a GL-5 type product can be aggressive toward yellow metals utilized in many standard transmissions or transfer cases.

BG Ultra-Guard® provides the ultimate protection for drive line components. As a professional-use product, it is formulated for increased thermal stability, improved seal performance, quieter operation, and unsurpassed protection against wear, pitting, and corrosion.
