Fox Internal Bypass Parts

Note: We do sell internal bypass shims (check valves) but we only carry the common sizes. There are a plethora to choose from. If you don't see what you're looking for, call us at 951.737.RACE for pricing and availability.

    We will need to know:
  • Shape of shim (oval or rectangular)
  • How many holes in the shim (usually 2 or 3)
  • Length of the shim from end to end
  • Width of shim
  • Thickness of the shim (usually 0.008" - 0.010" - 0.012" - 0.015" - 0.020")
We DO NOT have a way to reference what shims Fox put in your shock. You will have to take the shock apart to find out what's in it before you call us.
