Troubleshooting & FAQ
How do I know if this .030" oversize kit is right for my engine?
This kit is intended for engines where the cylinder has been machined or honed .030" larger than its standard bore. You must measure your cylinder's bore diameter to confirm it matches the 3.030" specification of this piston before purchasing.
What are the signs of a failing piston or rings?
Common symptoms include excessive blue or white exhaust smoke, a noticeable loss of engine power, increased oil consumption, poor compression test results, or a knocking sound from the engine.
Is this a complete kit for one cylinder?
Yes, this is a kit for a single cylinder, which includes the piston and the corresponding set of rings. If you are rebuilding multiple cylinders, you will need to purchase one kit per cylinder.
My engine model is listed, but the year is slightly different. Will it fit?
It might, but we only guarantee fitment for the specific model and year combinations listed in the compatibility table. Manufacturers often make mid-year changes. Always verify part numbers and specifications against your engine's service manual.
What is the difference between this aftermarket kit and the OEM one?
Functionally, they are identical. Our aftermarket kit is designed to meet or exceed original equipment specifications for material and tolerance, offering a cost-effective solution without sacrificing performance or reliability.
How often should pistons be inspected or replaced?
Piston replacement is typically done during a major engine rebuild or when symptoms of failure appear. There is no fixed replacement interval; it depends on usage, maintenance, and operating conditions.
OEM vs. Aftermarket?
This listing is an aftermarket replacement (not OEM). Built to OEM-level specifications with comparable materials. Manufactured in an ISO 9002 facility, batch-inspected for consistency.
Shipping speed & cost?
We ship worldwide quickly—typical transit 5–15 days. Standard shipping is free; expedited options appear at checkout where available.
Warranty & returns?
Covered by a 1-year warranty against manufacturing defects under normal use. If issues arise, contact support with your order details. Returns are accepted within our standard window (unused & in original condition). See our policy page or reach out for instructions.
Safety & Important Info
- Verify images/specifications vs your original part. If anything differs—even if your model appears compatible—do not purchase.
