Our shipping quotes are typically valid for only 7 to 14 days. If a CIF contract is signed and there are significant fluctuations in shipping costs due to war surcharges or route changes imposed by the shipping company before the vehicle is actually loaded, we will transparently provide you with the official price increase notice from the shipping company. At that point, we reserve the right to renegotiate the freight difference or allow you to change the trade terms to FOB, letting you designate your own freight forwarder for booking.

This is after-sales support we are very happy to provide. Since overseas alignment machines often lack databases for Chinese brand vehicles, we will send you screenshots of the core chassis parameters from the service manual, making it easier for your technician to manually input the data for precise adjustments.

We use two steps: 1. Insert a medical-grade endoscope through the spark plug hole to visually inspect cylinder wall scratches and carbon buildup on the piston top; 2. Extract an engine oil sample to check for large metal debris or emulsification (caused by coolant leakage).
