Motorcycle Fork Suspension Spring Preload Spacers

The compression spring inside your fork tube has an OEM conical spring perch that connects it to the inner damper cartridge, transferring energy. That main spring & its seat can be spaced up or down the height of the cartridge with different thicknesses of these collars or ring shims.

These spacers help set the correct spring pre load or adapt shorter springs to longer forks - learn more about coil springs & preload in our academy. We have multiple set sizes, but we also offer lengths of strong uncut steel tube & flat washer kits for the experienced DIY suspension tuner.

Before deciding you should check out our performance spring perch upgrades first though - the tough alloy bodies are much more durable & change fluid flow to tune for specific racing conditions.
