BG Ultra-Guard® LS Full Synthetic Gear Lubricant

BG Ultra-Guard® LS Heavy Duty provides the ultimate in simplicity and ease when servicing for drive line components, especially those requiring limited slip function.

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 Heavy Duty is formulated for unsurpassed durability by providing improved seal conditioning, quieter operation and dependable protection.

BG Ultra-Guard® Heavy Duty with LSII is a synthetic (Polyalphaolefin) API GL-5 rated gear oil blended to SAE 75W-140 viscosity. It satisfies all requirements for posi-traction and limited slip hypoid gears. No additive is required! New polymer-free technology extends oil life and virtually eliminates viscosity loss.
