All Balls fork seals use aPatented fork seal design that features a balanced 2 lip design on the oil (pressure) side that evenly distributes the pressure reducing operating temperature, wear and friction. A 3rd lip on the air side acts as an additional wiper to prevent dirt from contaminating the oil. A custom elastomer reduces stiction (friction) from 1/3 to 1/2 ; less than the OEM seals for smoother fork action. All kits include both oil and wiper seals.09:29 30/01/2021
