This is the same grease used in the bearings from the Eaton supercharger factory in early model superchargers. We recommend you pack and re-grease your bearings in higher mileage supercharger units, and whenever you change the bearings or rebuild your supercharger. If your supercharger has 150K miles or more will benefit from replacing the bearing grease.
Do not over pack or over fill your bearings.
NOTE: this grease is used in early EATON supercharger housing bearings. Later units use a tan grease (PN 001-07272). These two different greases should not be mixed. To check, dab a white paper towel on your bearings. The older grease has a blue tint, while the newer grease should look like regular grease. Make sure you are ordering the correct one, and if you’re not sure give us a call or send us an email.
