Package Includes:

(4 Fl. Oz) Positraction Oil Additive

- Friction Modifier is designed for use in limited slip differentials to minimize clutch chatter. All clutch style positraction units need friction modifier added to the gear oil during install. This will ensure the differential operates properly and its clutches are able to lock under load.
