Can the chassis of a sedan be raised?

Yes, it depends on the specific model and the adjustment items, such as single toe-in, four-wheel alignment, bearing clearance, bolt tightness, and many other items. Here is some relevant information: Advantages: If the chassis is low, it can enhance the car's grip. At high speeds, the body tends to be more stable. Additionally, it reduces the oncoming air pressure because the friction between the tires and the vehicle is significantly increased. Therefore, during high-speed driving, the controllability is higher, and the car is less likely to roll over in case of sudden situations. Disadvantages: Cars with low chassis can be very uncomfortable when encountering uneven terrain with significant elevation differences. The key issue is that they are more prone to scraping the undercarriage, which can damage the car's chassis. Moreover, some parking spaces require driving onto curbs, and low-chassis cars are more susceptible to undercarriage scraping.
I've been researching car modifications for many years. It is indeed possible to raise a sedan's chassis slightly, mainly achieved by replacing the suspension system, such as installing lift shock absorbers or adding spacer kits. However, this should be done by professional shops—don't attempt it yourself to avoid damaging chassis components. After raising, the vehicle's off-road capability improves, especially reducing undercarriage scrapes on rough roads, but handling will worsen, increasing body roll during turns and affecting safety. The cost isn't cheap either, typically ranging from hundreds to thousands of dollars depending on the car model. Additionally, post-modification wheel alignment adjustments may be needed to prevent rapid tire wear and increased long-term expenses. In summary, raising the chassis suits those frequently driving in rural areas, but for daily city driving, it's unnecessary and increases fuel consumption. It's advisable to assess needs and risks before deciding.
I've been driving for over a decade. I tried raising the chassis once because I felt sorry for my car scraping the bottom on dirt roads. Later, I spent over a thousand at a repair shop to install shock absorber lift kits. The effect was okay – the slightly higher chassis made driving over bumps easier, though not as great as I'd imagined. The car became wobbly and unstable, making me nervous even when overtaking on highways. For chassis lifting, it's best to choose professional modifications to avoid side effects. My friend did it himself and ended up with damaged shock absorbers, causing more trouble. The advantage is increased ground clearance, slightly better off-road capability, but fuel consumption rose by about 10%, making it impractical for daily commuting. Also, be aware that vehicle warranties may become void, and insurance companies might give you a hard time. Personally, I think lifting makes sense for poor road conditions, but it's completely unnecessary for city driving.
