• Grease caps are the small, round, metal covers you see at the very center of a wheel.
• Grease caps protect your wheel bearings from the dirt, dust, sand, water, salt and road grime that can (and will) destroy bearings.
• Without grease caps, your wheel bearings simply wouldn't survive for very long out on the road.

Trojan have available a range of Grease caps to suit most common Trailer hubs.
