FAQ

Q1: How do I confirm this piston ring set fits my specific engine?
A1: The most accurate method is to cross-reference the OEM part number from your engine’s service manual or the original rings. You can also provide your engine’s model and full serial number to our technical team for verification.

Q2: Are these rings pre-gapped, or is filing required during installation?
A2> While our rings are manufactured to precise tolerances, it is a critical best practice for engine rebuilds to always check and, if necessary, file the ring end gap according to the engine manufacturer’s service specifications. This ensures optimal sealing and performance.

Q3: What is the typical lead time for orders to [North America/Europe/Middle East]?
A3: Lead times vary by destination and shipping method. For standard sea freight to major ports in North America and Europe, expect 25-35 days. For the Middle East and Asia, 15-25 days is typical. Express air freight options are available for urgent requirements, significantly reducing transit time.
