KONI - Premier Manufacturer of Performance Dampers

Koni Offroad

A pioneer in this field since 1857, KONI provides leading, durable and experience-improving technology. KONI helps people move comfortably at whatever speed they desire, wherever they are.
KONI is everywhere from street cars to trains to industrial applications, such as bridges, being used in the most extreme conditions, including the dry Sahara desert and the freezing poles, proving that KONI dampers perform when tested.
As undisputed experience leaders, our technical capabilities and skills help develop, manufacture, and sell high-quality and top-performing hydraulic shock absorbers and suspension systems. Our goal is to create the best experience for everyone on the move.
Since 1857, KONI has established itself as the brand of choice for high quality products.

How it all started

KONI was founded in 1857 in Oud-Beijerland, the Netherlands, by A. de Koning. The business did not start with making shock absorbers, but with making leather equipment for horses. Just before the Second World War, the company started to work on shock absorbers. These were friction type shock absorbers. After the Second World War, the production of the telescopic shock absorbers started. In the early fifties, KONI decided to play a more prominent role in motor sports in order to enlarge the company’s reputation. In 1955, KONI participated for the first time in the Tulpenrally, a Dutch organized rally with international status. Rally was just the beginning and KONI soon after began its racing career, entering Formula 1. In 1956, while at the famous Nordschleife in Germany, KONI assisted the Ferrari team in solving their suspension problems. The first Grand Prix that KONI officially participated in was in 1958 with Ferrari. After that, the business expanded quickly and in 1971, KONI achieved its first World Championship win, as Tyrrell Ford won the driver’s and constructor’s championship. Over time, KONI has not only improved damping for rally cars and racing cars, but has also dedicated its expertise on improving the damping in various other commercial vehicles, and even for industrial projects like bridges.

Koni Active Technology

As a leading manufacturer of high performance shock absorbers KONI develops the technical features of all its dampers by following a simple principle: to meet the diverse demands of market applications with sophisticated, and  market leading mechanical solutions.

The everlasting problems with vehicle damping
Vehicle damping has always been a compromise between comfort and road-holding. An obvious example is a Formula 1 racing car which offers the best possible road-holding but with minimal comfort. In a personal or sport car one expects to experience the ultimate in comfort, combined with safe road-holding. Minimum damping is required for your comfort whilst strong damping is needed for safe and stable driving. This conflict of goals can not be solved with conventional front & rear dampers. Other damper systems currently available to the market do not offer an adequate solution:

Position-dependent shock absorbers will give you extra comfort, as they allow more movement of your car, but as a result the road-holding is inferior. Sudden bumps in the road will still be very unpleasant.

Pneumatic and electronic adjustable shock absorbers may improve road-holding in the future. The disadvantage of such complex systems is that they are very expensive and time consuming to set up correctly.

KONl shock absorbers with ACTIVE Damping technology offer the solution. Specifically designed for personal and sport cars, KONI Frequency Selective Damping technology combines the ultimate in comfort and road-holding. Being a purely mechanical technology, removes any cost, reliability, or complexity problems which can arise from using electronically controlled suspension components.

KONl ACTIVE high performance dampers are your first choice in solving the everlasting problem with vehicle damping.

Frequency Selective Damping principles
In general suspension terms, the conflict between comfort and handling can be split in two different frequency areas:

For comfort, with the suspension moving in a high frequency area (± 10 Hz), it is neccessary for low damping forces for the vehicle to remain comfortable.

For handling, with the suspension moving in a low frequency area (± 1 Hz), it is neccessary for high damping forces for the vehicle to remain safe and in control.

Conventional dampers are unable to solve the conflict in terms of comfort and handling, however if you are able to create a damper which can change the damping force level in relation to the frequency of the movement, you will be able to solve this conflict.

KONI ACTIVE technology does just that!

How does it work?
In standard shock absorbers the main damping characteristic is defined by the oil flow going through the piston assembly.


Combining this standard damping characteristic with the ACTIVE feature, KONl added a special valve (seen above) which is able to control a parallel oil flow next to the one going through the piston. This parallel oil flow is closed by the Active feature, giving a rise in damping force almost linear to the time that the piston is moving in one direction.

Put simply: the KONI ACTIVE feature is a hydraulic amplifier that delays the build up of pressure. One could say that an extra tuning option has been created in order to get the best possible combination of handling and comfort.

Since it is an integrated part of the hydraulic valve system inside the damper, no additional cables, sensors or any other electronic devices are needed to operate a KONI ACTIVE damper.

In comparison with costly systems which work on the basis of computer technology, complex electronics and sensors, KONI ACTIVE the simplest and most economic way to significantly improve the ride and driving characteristics of every car.
