This Lainer Suspension rebound piston rod is a dimension-specific internal component for KYB fork cartridge assemblies. It is used during cartridge service and rebuild work where shaft length and diameter must match the original parts for correct assembly. Suitable for suspension technicians and experienced mechanics working with KYB cartridge internals.

Inside the System

The rebound piston rod forms part of the cartridge rod assembly and must match the required diameters and overall length for the cartridge to assemble and operate correctly. This part is specified as 12.5 mm outside diameter with a 6.0 mm inside diameter, and a 387.0 mm shaft length.

Compatibility

  • Intended for KYB fork cartridge applications that require a 12.5 mm outside diameter rebound piston rod
  • Specified dimensions: Outside Ø D 12.5 mm, Inside Diameter d 6.0 mm, Shaft Length / Height H 387.0 mm
  • Confirm measurements and cartridge design before ordering to avoid mismatch during assembly

Serviceability

Replace the piston rod when it is bent, damaged, corroded, or when wear prevents correct assembly or reliable function during a rebuild. It should also be changed when the existing rod does not meet the required dimensions for the cartridge being built. Do not replace it if the rod is straight, serviceable, and already matches the required measurements for the application.

Setup & Workshop Notes

  • Dimension checks are critical in cartridge work—verify OD, ID and overall length against the parts removed
  • Keep components clean during assembly to reduce the risk of internal damage during service
  • Sold individually

Next Steps

If you are unsure of the correct cartridge rod specification for your KYB fork, measure the original parts and confirm the required OD, ID and length before proceeding with the rebuild.
