Will these work with my current wheels?

These are M12 x 1.25 metric fasteners — verify your wheel hub matches this thread pattern before ordering. If you're running aftermarket wheels with spacers, the extended length design gives you the extra reach you need.

Do the aluminum covers come pre-installed?

The covers are assembled and ready to install on your wheel hubs — no additional setup required.

Can I clean these without damaging the gold finish?

Warm soapy water works fine for routine maintenance. Avoid abrasive scrubbers or harsh chemicals that can wear the anodized coating. Dry with a soft cloth to prevent water spots.
