## FAQ

### Is this an original part or an OEM-quality replacement?

All parts in our catalogue are factory-made OEM replacements, not original KAMAZ parts. They are produced to the original drawing dimensions: forged blank, heat treatment and machining under IATF 16949. Every batch passes outgoing inspection at the factory. We do not sell used or refurbished parts.

### How do I make sure the part fits my truck?

Match the drawing (catalogue) number on this page with the number in your vehicle parts catalogue or on the old part. If in doubt, send us the number, a photo of the part or your truck model via WhatsApp — we will confirm fitment and suggest interchangeable numbers.

### What warranty do you provide?

We stand behind factory quality: if a manufacturing defect is found on receipt or during installation, send photos/video — once confirmed, we will replace the part or refund it. Warranty terms are fixed in the commercial offer.

### What is the MOQ for this item?

Standard MOQ is 50 pcs per item; for large or expensive parts the threshold is negotiable. Different items can be combined in one order.
