Know before you buy
This kit is specifically designed for Fox forks with 40mm stanchion diameters, such as the Fox 40 series. You should verify your fork model and stanchion size before purchasing, as these are not universal across all fork diameters.
The low-friction design reduces the stiction—or static friction—between the seals and the stanchions. This results in a more sensitive, plush suspension feel that reacts more quickly to small trail chatter.
As a general rule, you should replace your dust wipers every 125 hours of riding or at least once a year. If you frequently ride in muddy, dusty, or wet conditions, you may need to service them more often to prevent debris from entering the lowers.
Yes, this is an authentic Fox Racing Shox component. Using genuine parts ensures the correct fit and material specifications required to maintain your fork's performance and warranty.
Yes, you will need a seal driver tool specifically sized for 40mm stanchions to seat the wipers correctly without damaging them. It is also recommended to have the appropriate suspension fluid on hand for the service.
