Frequently Asked Questions

What does this foam seal do?

It creates a watertight and dust-tight seal between the primary cover and the crankcase to prevent fluid leaks.

How many seals are in a pack?

One foam seal per pack — a single replacement for your primary housing.

Is this a direct replacement for my Sportster?

Yes, for Sportster models using this primary housing design. Verify the part number matches your bike before ordering.

Do I need to replace this every time I open the primary?

The foam can be reused if it's still pliable and not damaged. Many riders replace it once per rebuild or if leaks develop.
