We stand behind every product we sell with a clear warranty policy and responsive after-sales support.

Warranty period: All engine components come with a 6-month warranty from the date of installation, covering manufacturing defects in materials and workmanship. Wear items (filters, brake pads, seals) are covered for 3 months. Electrical components (starters, alternators) carry a 12-month warranty.

How to make a claim: If you encounter a quality issue, contact your assigned sales engineer with the following information: part number, batch code (from packaging label), photos of the defective part, and a brief description of the failure. Our QC team will review the claim within 48 hours.

Resolution options: For confirmed manufacturing defects, we offer free replacement parts shipped with your next order, or a credit note toward future purchases. In urgent cases, we can ship replacement parts via express delivery. We do not require return of defective parts for claims under $500; for higher-value claims, we may request return shipment at our cost.

Technical support: Beyond warranty claims, our engineering team provides free technical support including installation guidance, torque specifications, cross-reference lookup, and troubleshooting. Response time is within 12 business hours via email, WhatsApp, or WeChat.
