This is a universal wheel hub dust cap designed to press into the center of a wheel hub.
Confirm the part fits before you buy. Applications and interchange numbers are researched and audited per part.
We don't publish fitment for this part yet. Rather than guess, get it confirmed against your truck in under a minute.
Its primary job is to keep dirt, water, and road debris out of the wheel bearings, which prevents premature wear and bearing failure. You would replace it if the original cap is missing, damaged, rusted out, or if it has fallen off, leaving the hub nut and bearings exposed. This particular version is anodized blue and made from aluminum, featuring a Moser logo.
