System Specifications

MOPAR Gear Lubricant or equivalent thermally stable SAE 80W-90 API-GL5 grade.

For trailer towing applications, use SAE 75W-140 synthetic gear lubricant.

Limited-Slip Trac-Lok differentials require the use of a friction control additive such as MOPAR Hypoid Gear Oil Additive Friction Modifier. This should be added to the gear lubricant whenever a fluid change is made.
