API GL-5 Hypoid ring and pinion gear sets, operating under high load with positive traction clutch packs or “on demand” limited slip function, are used in many front and rear axle drivelines. For proper function many of these units require the final lubricant to contain both a GL-5 lubricant and a fully active limited slip additive.

Together these two finished lubricants provide the designed drive performance and protection needed by the gears. Standard practice has been to add these two lubricants together individually, usually from separate sources. This can leave open the possibility of improper treat ratios, possibly creating inferior driveline performance and protection. Stocking these separate lubricant containers also created excessive inventory. BG Ultra-Guard® LS Full Synthetic Gear Lubricant contains all the necessary ingredients required for API GL-5 rated gear applications, and also those requiring the addition of limited slip chemistry for positive traction, or “on demand” driveline systems.

As a full synthetic SAE 75W-90 API GL-5 gear lubricant, it is designed for severe service operation in both extreme heat and arctic cold conditions. BG Ultra-Guard® LS Full Synthetic Gear Lubricant is formulated for unsurpassed durability by providing improved seal conditioning, quieter operation and dependable protection. It is a universal product for all SAE 75W-90 API GL-5 lubricant applications.

BG Ultra-Guard® LS Full Synthetic Gear Lubricant is part of the BG Drive Line Service.
