Troubleshooting & FAQ
How do I know if my main bearings are failing?
Signs of worn main bearings include a deep, rumbling or knocking sound from the bottom of the engine, low oil pressure readings, and the presence of metallic flakes or shavings in the engine oil during an oil change.
Is this kit all I need for a bottom-end engine rebuild?
This kit contains the main bearings for the crankshaft. A complete bottom-end rebuild would typically also require connecting rod bearings, and potentially piston rings and other seals or gaskets. Always consult your engine's service manual.
What does "Special Order Item" mean for delivery time?
As a special order item, this part is not held in our regular inventory and is ordered directly from the manufacturer. This may result in an extended lead time before shipping. Please contact us for an estimate.
Do I need to measure my crankshaft before ordering?
Yes. This is a standard-size bearing kit. If your crankshaft has been previously machined or shows significant wear, you may require oversized bearings. Professional measurement is highly recommended to ensure you order the correct size.
What’s the difference between OEM and aftermarket parts?
This listing is for an aftermarket replacement, not an OEM component. It has been engineered to meet or exceed OEM-level specifications using comparable materials. Our parts are manufactured in an ISO 9002 certified facility and are batch-inspected to ensure quality and consistency.
How much is shipping and how fast is it?
We ship worldwide, with most orders arriving in 5–15 days via standard delivery. Standard shipping is free for most regions. Expedited shipping options, where available, will be displayed at checkout.
What is the warranty and return policy?
This product is covered by a 1-year warranty against manufacturing defects under normal operating conditions. If you encounter an issue, please contact our support team with your order details. Returns are accepted for unused items in their original packaging within our standard return window. Please see our full policy page or contact us for instructions.
