What are Suspension Springs?

The coiled metal springs that keep your wheels on the road and your ride comfy.

Car bodyBumps in → springs compress, shocks damp → smooth ride out

Simplified animation — not to scale.

In plain English

Suspension springs sit between each wheel and the body of the car. They absorb bumps in the road, hold the car's weight up, and keep all four tyres pressed against the tarmac for grip.

A simple analogy

"Like the springs under a mattress — they let you sit comfortably and absorb the shock when you flop down."

How it works

Most cars use coil springs — thick steel coils that compress when a wheel hits a bump and push back as it returns. They work hand-in-hand with shock absorbers (dampers): the spring soaks up the hit, the damper stops it bouncing back too fast. Without springs, every pothole would slam straight into the chassis.

  • ⚠Knocking or clunking over bumps
  • ⚠Bouncy, floaty ride or excessive nose-dive when braking
