BG Ultra-Guard® Heavy Duty provides the ultimate protection for drive line components. Specifically designed for heavy duty and commercial vehicles, it has 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® Heavy Duty will withstand the punishing effects of extreme heat and arctic conditions and is one of the few polymer-free gear lubricants to meet the stringent requirements of Ford engineering spec WSL-M2C-192-A. It can be used in all conventional and limited slip differential hypoid gear rear axles.
