The Fox Racing Shox Seal Driver Tool is specifically designed to press new dust wipers into your Fox fork. Simply choose the corresponding size for your fork's stanchion diameter, press until they are seated, and you're good to go. No more makeshift press jobs using PVC pipe or improperly sized sockets. The seal driver is available in 32mm, 34mm, 36mm, and 40mm diameters to cover any type of Fox fork.
