Limited-Slip Axle Lubricant Additive, 4 Ounces by ACDelco®

Friction modifier for limited-slip differentials that specify the GM additive.

Use the lubricant grade and additive amount specified for the particular differential; do not assume every limited-slip axle requires the same dose.

• Limited-slip axle friction-modifier additive • ACDelco® reference number 10-4003 • Supplied in one 4-ounce bottle • Use the differential manufacturer’s specified dosage
