About KYB Suspension

Porsche KYB Suspension

At Design911, we supply KYB suspension components for Porsche models, drawing on KYB’s long-standing expertise in hydraulic technology and shock absorber manufacturing. KYB produces millions of dampers each year for vehicle manufacturers and the aftermarket, making it a widely trusted choice when you want to restore stable, controlled ride quality on the road.

Why do KYB Suspension parts matter?

KYB suspension components help your Porsche maintain consistent damping control, support comfort and stability, and keep the car feeling composed over everyday roads. As original dampers age, they can lose efficiency, leak, or become inconsistent side to side. Fitting quality replacement parts from a specialist such as KYB is a straightforward way to bring the chassis back to how it should feel and support long-term enjoyment of the car.

  • Keep your Porsche looking and feeling well cared for rather than tired or neglected
  • Help protect tyres and other suspension components from the effects of poor damping
  • Reduce minor niggles such as excessive bounce, floatiness or uneven behaviour between sides
  • Support long-term enjoyment, pride of ownership and potential resale value

Common options & kits

Brands available in this category

For this category we stock a wide choice of trusted brands for Porsche models. You can also browse and filter by brand on this page to focus on your preferred manufacturers.

  • KYB – For almost a century KYB has specialised in hydraulics, with technology widely used in the automotive shock absorber industry. KYB is Japan’s leading hydraulics company and KYB Europe is based in Dusseldorf, Germany, supporting Porsche applications across Europe and North Africa.

When should you review or replace your KYB suspension?

Checking KYB suspension components regularly helps you spot wear, leaks or age-related deterioration before it affects comfort, refinement or leads to more expensive suspension repairs later on. KYB replacement dampers are typically chosen when you want a dependable, predictable ride rather than a radical change in character.

  • Existing dampers are bouncing excessively, feel “floaty” or allow too much body movement
  • You notice knocks, rattles or see oil leaks on the damper body
  • Tyres show uneven wear patterns that may be linked to poor damping control
  • You are refreshing other suspension parts and want the car to feel consistent and tight again

If any of these apply, it is a good time to review your KYB suspension options and replace anything that is past its best so your Porsche stays dependable and enjoyable to drive.
