This steel grease cap (also called a dust cap) presses into the outer end of a trailer hub to protect the wheel bearings from dirt, water, and debris.
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.
It has a 2.72-inch outer diameter and fits heavy-duty hubs typically found on 5,200 to 8,000‑pound axles with an 8‑bolt pattern. It’s a simple drive‑in design, and you replace it whenever the old cap is damaged, missing, or when servicing the bearings to maintain a clean, sealed hub assembly.
