Can Modified Suspension Pass Annual Vehicle Inspection?
2 Answers
Modified suspension can generally pass annual vehicle inspections because inspectors typically do not crawl under the vehicle to check. Below are the relevant regulations regarding vehicle modifications: 1. Modifications within permitted scope: Any changes to the vehicle must comply with the limits set by the traffic management authorities. This includes modifications to body color, engine, fuel type, and vehicle identification number. Drivers must submit an application and obtain approval from the traffic management department before proceeding with modifications. 2. No unauthorized assembly or alterations: No individual or organization is allowed to assemble vehicles or modify the registered structure, construction, or features of a vehicle without authorization. 3. Modifications require approval: Unauthorized modifications to the chassis, engine, suspension, transmission system, steering system, wheel rims, lights, body color, or exterior structure, as well as any technical data that does not match the specifications announced by the national vehicle product authority, are considered illegal modifications.
I previously helped my neighbor modify his suspension, and he felt the car drove more steadily after the changes. However, during the annual inspection last year, it got flagged. The inspectors said suspension modifications that significantly alter the vehicle's height or affect handling can easily fail the inspection. In most regions of China, the vehicle management office requires that suspension modifications must not alter the original structure and must comply with safety standards, such as keeping the height change within 2-3 cm. My advice is to check local modification regulations or consult a professional shop before making changes, and choose products from reputable brands. If the modifications violate regulations, you’ll have to spend money to revert them, and failing the inspection will waste time. Now, he’s learned his lesson and only makes minor adjustments to ensure compliance and peace of mind. Car modifications are meant to improve driving, but they must follow the rules.
