BG ULTRA-GUARD REAR AXLE LUBE QUART
This is a premium quality product that offers extended protection and is designed for long life at extended operating temperatures. This oil is compatible with all Limited Slip, Traction Lock and Torsen Type Differentials. This product directly replaces the factory fill fluid. It is blended with additives for proper differential operation, eliminates clutch chatter and clunky-ness. No additional additives need to be added for proper operation and performance. You can even use the container to return your used oil to your oil-recycling center.
***We now offer the Ultra-Guard without additive for Track Mustangs with Torsen differentials***
***Available in 75W-90 and 75W-140***
If your Mustang see more track time than street time We suggest choosing the Ultra-Guard without the "LS" Limited Slip Additive. In Torsen equipped vehicles removing the additive theoretically will improve the Bias properties of the Torsen on track. Ford uses the additive to 'calm down' the Torsen on the street. Torsens typically will pop and bang during low speed turns which is normal and does not affect the life of the unit. On track with improved Bias the differential can offer improved lock up allowing for more power to the wheels on corner exit.
If you still daily drive your Mustang we recommend running the LS Ultra-Guard to maintain 'street manners' If you have a clutch type differential continue to use the "LS" version.
BG Products Ultra-Guard® LS Full Synthetic Gear Lubricant provides the ultimate protection for drive line components. It is a full synthetic API GL-5 rated gear lubricant blended to SAE 75W-90 viscosity to perform in extreme heat and artic conditions. BG Ultra-Guard® LS is formulated for increased thermal stability, improved seal performance, quieter operation and unsurpassed protection against wear, pitting and corrosion. Excellent for use in conventional and limited slip applications. The addition of a supplemental friction modifier is not required.
PROBLEM: 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 modern 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.
SOLUTION: BG Ultra-Guard® LS Full Synthetic Gear Lubricant provides the ultimate in simplicity and ease when servicing for drive line components, especially those requiring limited slip function. 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.
