PolarStar Kythera SA Pin Set
The PolarStar Kythera SA Pin Set is the OEM replacement set of internal retaining pins for the PolarStar Kythera SA HPA engine. Internal pins in the Kythera SA secure components in their correct positions within the engine assembly — pins can be lost during engine servicing or strip-down, or can wear and loosen over extended use. Having the correct OEM pin set allows a complete engine service or rebuild without sourcing individual pins separately.
OEM PolarStar replacement pin set specific to the Kythera SA — the SA variant uses different internal geometry to the standard Kythera and Kythera M3. For Kythera SA operators who have lost pins during maintenance or require a full service pin set, this is the correct OEM pin set for the SA variant.
