Air suspension is very delicate. If, after the vehicle has been stationary for about 12 hours, the height on one side of the vehicle drops more than 1.5 cm when measured from the wheel arch to the tire, we will determine that there is a slight air leak in the air spring or distribution valve on that side and warn you of the high subsequent repair costs.
You are very welcome. We adhere to the principle of open and honest transactions. Just make an appointment in advance, and your agent or hired inspector in China can bring equipment into our facility to conduct unrestricted cross-inspections on the vehicles you have booked.
