Frequently Asked Questions

Q: What size trailer hubs are these 48mm dust caps compatible with?

A: These galvanized steel trailer hub dust caps are designed for hubs with a 48mm center diameter. They are specifically a replacement for Alko brake drum hubs (non-European version). Always measure your hub's center bore before ordering to confirm fitment.

A: No special tools are required. The caps feature a simple press-fit design that allows for quick and easy installation by hand, making them ideal for DIY trailer maintenance and roadside repairs.

Q: Why is it important to use a dust cap on my trailer wheel hub?

Keeping your dust caps in good condition is essential for safe towing.
