Patented fork seal features a balanced dual lip design (oil side) that evenly distributes the pressure reducing operating temperatures, wear and friction. A 3rd lip (air side) acts as an additional dust wiper. Custom Elastomer reduces stiction by 1/3 to ½ less than OEM seals for a smoother fork action and extended life.
