What does car pneumatic modification mean?
2 Answers
Car pneumatic modification refers to the modification of pneumatic suspension, which can be raised or lowered, and the stiffness can also be adjusted. This type of suspension adjusts the vehicle height and suspension stiffness by inflating or deflating. Some luxury cars or luxury SUVs have pneumatic rear suspensions to enhance comfort and off-road capability. The working principle of pneumatic shock absorbers involves controlling air pressure to adjust the vehicle height, consisting of elastic rubber airbag shock absorbers, an air pressure control system, a trunk-mounted air tank, and an electronic control system. Most pneumatic suspensions include an air tank and an air pump, with the spring being an airbag. By inflating or deflating this airbag, the vehicle height and suspension stiffness can be adjusted.
Simply put, car air suspension modification means replacing conventional springs with airbag-equipped suspension systems. It uses an electric air pump to inject high-pressure gas into rubber airbags for adjustable ride height, offering more flexibility than traditional springs. A friend of mine installed air suspension for his lowrider stance build—it can squat so low when parked that the tires nearly tuck into the wheel arches, then raise up while driving to avoid scraping the undercarriage. The setup requires a full kit including air tanks, lines, and controllers, with professional installation starting around ¥20,000. But be warned: air suspension demands extreme installation precision. Leaky lines or subpar airbags could lead to sudden deflation while driving, which is downright dangerous.
