Not included in the standard fork seal package, the circlip and washer are often needed items when doing a rebuild of the forks. The circlip can get corroded and lose it's springiness, while the washer gets a groove worn into it. For a small price, it's a good idea to go ahead and replace these components while you're doing the full job.
Sold only with the purchase of other front suspension components.
And of course shipping to the lower 48 states is included in the price!
