Product Information

Koni Special Active front shock absorbers & top mounts kit – Porsche 986 Boxster by Koni is for Porsche Boxster 986 models from 1997–2004, including 2.5L, 2.7L and Boxster S 3.2L variants. This front kit combines Special Active dampers with top mounts for a matched suspension refresh on the front axle.

What This Product Does Front shock absorbers control vertical wheel and suspension movement, help maintain tyre contact and manage body movement during braking, cornering and acceleration. Koni Special Active dampers use Frequency Selective Damping technology to vary damping response according to road and suspension movement, while the included top mounts support correct installation at the strut-to-body mounting point.

Functions

  • Controls front suspension travel and wheel movement.
  • Helps manage nose dive, pitch and body roll.
  • Supports consistent front axle behaviour when fitted as a pair.
  • Replaces ageing front dampers and associated top mounts together.
  • Helps address wear-related knocking where top mounts are part of the cause.

Symptoms of Fault

  • Leaking oil on the damper body.
  • Excessive bouncing after bumps.
  • Nose dive under braking.
  • Knocking or creaking over uneven roads.
  • Vague steering response or tramlining.
  • Uneven tyre wear or cupping.
  • Poor body control or unsettled ride feel.
  • Harshness caused by worn mounts, bushes or incorrect spring pairing.

Why Replacement Matters

  • Front dampers are commonly replaced to restore ride control, braking stability and handling feel when original parts are worn.
  • Replacing top mounts at the same time can reduce repeat labour and address related suspension noises.
  • Koni Special Active dampers are often chosen for road cars where controlled damping and everyday compliance are both required.
  • Suspension issues can overlap across dampers, mounts, arms, bushes and alignment, so inspect the wider front suspension before fitting.
  • After suspension work, have the wheel alignment checked to support consistent handling and tyre wear.

Fits

  • Boxster 986/987/981 (1997–2016)
  • Boxster 986/987/981 (1997–2016) => Boxster 986 2.5L 1997–99

Check fitment for your specific vehicle (model, year, engine) before ordering.

FAQs

  • Should front shocks be replaced in pairs? Yes, left and right front dampers are normally replaced together for balanced axle behaviour.
  • Are new top mounts worth fitting? They are often recommended when the existing mounts are old, noisy or being disturbed during damper replacement.
  • Are these dampers adjustable? Some Koni products are adjustable; confirm the exact specification for this kit and follow the supplied fitting instructions.
  • What should be checked after fitting? Inspect related bushes and arms, then have the alignment checked once the suspension work is complete.

About Koni Special Active

Porsche Koni Special Active

Koni Special Active is designed for Porsche owners who want more control and composure from their suspension without sacrificing everyday ride comfort. Using Koni’s latest valve technology, these dampers adapt their behaviour to driving conditions, offering a more supple feel over small bumps while providing firmer control when body movement increases, such as during faster cornering or heavier braking. At Design911, we offer Koni Special Active applications for a wide range of Porsche models, helping you update ageing suspension with a modern, road-focused upgrade.

Why do Koni Special Active dampers matter?

As Porsche suspension components age, original dampers can lose their ability to control movement smoothly, leading to bouncing, float, and a less settled feel. Koni Special Active dampers are designed as a high-quality replacement that brings your Porsche up to date with more sophisticated damping behaviour than many factory-fit units. They work to calm unwanted body motion when you ask more of the car, yet remain compliant in normal driving, making them particularly suited to road-going Porsches that see mixed use.

  • Help your Porsche feel more composed and controlled in everyday and brisk driving
  • Offer a blend of comfort and body control suited to fast-road use
  • Address age-related damping fade, bouncing and poor body stability
  • Support long-term enjoyment and a more modern, reassuring suspension feel

Common options & kits

Individual replacement dampers

Specific front or rear Koni Special Active dampers can be chosen to replace worn components on a particular axle or to tackle issues step by step. This is useful if you are refreshing the suspension in stages, or where one end of the Porsche shows more obvious wear.

  • Good for targeted repairs or staged suspension upgrades
  • Lets you focus on the axle with the most noticeable issues first
  • Can be combined later with matching dampers at the other end of the car

Matched axle sets or pairs

Front or rear pairs of Koni Special Active dampers ensure both sides of an axle behave consistently, which is important for predictable handling and a balanced feel from left to right.

  • Promotes consistent behaviour across the axle
  • Helps avoid uneven damping and steering feel
  • A sensible choice when renewing tired factory suspension

Complete car sets

In some fitments, full sets of Koni Special Active dampers allow you to refresh all four corners of your Porsche in one go. This is ideal if you are completing a broader suspension overhaul, pairing with new springs, or bringing an older car up to a more modern standard of comfort and control.

  • All specified dampers supplied together for your model
  • Saves time versus sourcing individual components separately
  • Well suited to restorations or comprehensive suspension refresh projects

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.

When should you review or replace your Koni Special Active or other dampers?

Reviewing dampers and related suspension components at intervals helps you identify wear before it noticeably undermines how your Porsche feels. Even without obvious leaks, damping performance can decline gradually over time and mileage.

  • You experience increased body movement, float or bouncing over undulating roads
  • The car feels less settled in faster bends, even on familiar routes
  • Existing dampers show signs of leakage, corrosion or age-related fatigue
  • You are upgrading springs or bushes and want the dampers to match the improved setup

If any of these apply, it is a good time to assess your suspension and consider Koni Special Active as part of a well-matched refresh so your Porsche remains stable, comfortable and enjoyable to drive.
