3" Dust Cap

Dust caps should be empty when installed and filled with catching excess grease once on the highway.

It is common for folks to call dust caps, grease or oil caps. Dust caps catch excess grease. However, the standard procedure for service mechanics to load up the dust cap with grease is not a good practice. The overloaded bearing cavity and dust cap will eventually expel excess bearing grease out of the rear grease seal.

Dust caps perform two functions:

1. Keep Dust out
2. Catch excess bearing grease

Suit 75mm or 3-inch hubs, hub drums and disc rotors.
