Frequently Asked Questions (FAQ)

Q: Why are genuine overhaul kits superior for engine maintenance?

A: Genuine kits maintain the manufacturer's original design tolerances. Using non-genuine parts often results in thermal expansion mismatches, leading to premature engine failure. Our kits are OEM-authorized, ensuring long-term reliability.

Q: How do you ensure compatibility for international clients?

A: Our expert team uses a dual-verification system—matching your chassis/engine number (VIN/ESN) against our database of proprietary parts catalogs before shipment.

Q: What is the typical lead time for overseas shipping?

A: Leveraging our location in Nanning and proximity to major ports, we offer expedited shipping services, often consolidating orders to minimize freight costs for our partners in the Middle East, Africa, and Southeast Asia.
