What size of upper bearing seal do I need for my frame?

The upper bearing seal comes in three sizes and is not optional when used with either a Headshok or a Lefty fork. The inner diameter is the same on all sizes, but the outer rubber cover is different. QSCSEAL, QSMSEAL, QSISEAL are the three part numbers.

  • QSMSEAL – 50mm outer diameter
  • QSISEAL – 58mm outer diameter
  • QSCSEAL – 60mm outer diameter
