Frequently Asked Questions

What is a fork seal back washer?

It's a support washer that sits behind the fork seal to prevent fork oil from leaking past the seal assembly and to maintain proper seal pressure.

Why buy a 2-pack?

Two washers cover both fork legs. Having spares on hand is useful for shops or multi-bike service.

Will this fit my Sportster?

This part is for big twin engines. Sportster and other smaller-displacement V-twins may use different washer sizes — verify your application.

Do I need to replace these when I service fork seals?

It's best practice to replace the back washer when installing new fork seals to ensure proper seal function and prevent future leaks.
