Key Features & Benefits

These control the movement of your springs. Now, your springs support the weight of the vehicle, but they keep bouncing after you hit a bump. The shock absorber’s job is to dampen that bounce, to slow it down and stop it happening over and over. It’s basically a hydraulic pump that turns that up – and – down motion into heat, which gets dissipated. They don’t support the weight, they control the motion after the springs react to it. They're a key part of your suspension system, obviously. It’s the bit that keeps your tires in contact with the road as much as possible. Each wheel has one, usually. They work with all the other suspension bits – springs, struts, control arms – to give you a comfortable ride and keep things stable, especially when cornering or going over uneven surfaces. Think of it like this: the springs absorb the initial hit, but the shocks control how that energy is released.

Symptoms, Risks & Replacements

Well, if your shocks are worn out, you’ll notice it. The car will bounce more, feel floaty, and it'll take longer to stop. That extra bounce actually reduces your tire contact with the road, making braking less effective and handling sloppy. It also puts extra stress on all the other suspension components, meaning they’ll wear out faster too. Plus, a really bad shock will make your ride seriously uncomfortable. It acts like a shield against the worst bumps, and when that shield fails, you feel everything. You can find replacements pretty easily, Fixparts Online has a good selection, and replacing them will bring back a lot of your car's handling and ride quality.
