Intrax History [看中文版]


Intrax is a Dutch manufacturer of high-end suspension technology with over 40 years intense experience at the highest levels of racing/rallying. Intrax designs and produces shock absorbers, springs and suspension technology for Formula 1 cars, street cars and everything in between. All Intrax shocks are custom build with a personal setting specially calculated for your car and your requirements.  

Intrax is situated in the South of Holland (Volkel) at one hour drive from Amsterdam and the airport Schiphol. Intrax is founded in 1994 by Henk Thuis, the same man who founded and raised the legendary White Power Suspensions. Under the umbrella of Henk, other suspension companies like Technoflex, Hyperpro, Ohlins Holland and Wilbers Suspension have been started.  

Throughout the years, several World Championships have been obtained with the suspension designed by Henk Thuis in the motorcross, motorbike roadracing, enduro, mountainbiking and several Formula classes like the F3000 and Formula 1. Henk himself is also active as a driver. He is the current champion in the “Dutch Supercar Challenge” 

At the end of the White Power Suspensions period, the interest and love of Henk for car suspensions grew. His involvement at the F1 world championships of Benetton and Michael Schumacher, combined with the car racing Henk was doing himself, made Henk decide to start a new company that was dedicated to car suspension technology. The birth of Intrax was a fact.


After 20 years of intensive developments Intrax has developed a wide product range of high-quality lowering springs, shock absorbers, height adjustable coilover kits, adjustable shock absorbers and complete suspension packages. We also mount our own suspensions in our workshop. For competition usage we can align and set the correct corner weight.

A special department within Intrax prepares, modifies and builds complete streetcars, trackday cars, race and rally cars for each budget and at all levels. Intrax coordinates, runs and supports several car race classes.

You are cordially invited to visit Intrax with your car. You can make a short test drive together with one of our experts. This test drive together with your preferences will enable us to advice the right suspension for you.

The uniqueness of Intrax is that we can build a tailor-made package. We guarantee that you are satisfied with our suspension. Our products are always upgradable and rebuildable. Therefore an investment in Intrax suspension components is always the right decision.

Settings

We take suspension serious. Therefore we offer for most applications different settings on the spring rates, shim stacks and damping pistons:

  • Fast street / occasional trackday. 

An upgrade to the sportive side from the OEM equipment. Daily comfort, vibration and noise levels are just as important as handling. 

  • Trackday / bumpy race circuit / Nordschleife. 

A suspension to race on both smooth and bumpy circuits. It is possible to ride to- and from the circuits. Ride height is enough to drive on public roads. Laptimes and handling are more important than comfort levels. 

  • Full-race / Rally. 

Stiff suspension, designed to work with slicks and rollcage fitted. Not useable on the street. Lap time optimized. 

Being a small and effective factory with a large network build up in the 35 years we are in business, Intrax is in the unique position to develop and manufacture “one-off” and “private label” solutions for suspensions.

Some (race) cars that are equipped with Intrax shock absorbers:

  • – ALfa Romeo 75 Imsa
  • – Aquilla 
  • – BMW E46 WTCC
  • – Citroën DS-5
  • – Ferrari 458 GT3
  • – Land Rover Defender
  • – Mercedes G AMG
  • – Oreca silhoutte
  • – Porsche 997 RSR
  • – Radical RXC
  • – Viper GT3-R

Over the past years helicopters, ice-cream trucks, classic racecars, motorbikes, mountain bikes and even horse carriages have left our factory riding on our suspensions.

- Winning Examples !! -

Intrax owns the absolute lap record for street legal cars at the well known “Nordschleife” of the Nürburgring. In 2009 a “Radical SR8LM” equipped with Intrax 4-WAY dampers lapped in 6m48s. This makes the Radical’s more than 23 seconds faster than the first competitor. See the link below and several youtube movies.
