What are Shock Absorbers?

The oil-filled tubes that stop your car bouncing after every bump.

Simplified animation — not to scale.

In plain English

Shock absorbers (or "dampers") sit alongside each suspension spring. While the spring soaks up a bump, the shock absorber controls how fast it bounces back — keeping the tyre planted on the road instead of pogo-ing into the air.

A simple analogy

"Like the closer on a fire door — the spring would slam it shut, but the damper makes it close smoothly."

How it works

Inside each shock is a piston moving through hydraulic oil. Tiny valves restrict the oil's flow, converting bounce energy into heat. Worn shocks let the spring oscillate freely — extending stopping distances, ruining handling and chewing up your tyres.

Signs of trouble

  • Car bounces more than twice when you push a corner down
  • Nose-dive under braking or sway through corners
  • Uneven, cupped or scalloped tyre wear
  • Oily film leaking down the side of the shock
  • Knocking over speed bumps
