FAQ

Q: How can I confirm this flywheel gear fits my Isuzu 4JG1 engine?
A: While this part is designed to OEM specifications for the 4JG1 engine, we recommend verifying the tooth count, inner diameter (bore), and overall diameter of your existing flywheel gear. Please compare these measurements with the product you receive. If you are unsure, contact us with your engine serial number for confirmation.

Q: Is this a complete flywheel assembly or just the gear ring?
A: This product is the flywheel gear (ring gear) itself. It is the toothed ring that is pressed or welded onto the flywheel. It does not include the main flywheel body. Installation typically requires a press or specialized tooling to fit the new ring gear onto the flywheel.

Q: What is the typical lead time for international orders?
A: Lead times vary based on order quantity and destination. Small orders (1-10 pieces) are typically shipped within 3-5 business days via express courier (DHL, FedEx, UPS). Larger bulk orders may require 7-15 business days for production and will be shipped via sea or air freight. Please contact us for a precise shipping quote for your location.
