Originally Quantum Suspension Technology — founded by ex Penske and Fox Racing Shocks engineer Ken Anderson —QUANTUM was established for the sole purpose of supplying an innovative new shock to the Onyx Formula One team — and subsequently others including Arrows, Brabham, Ligier, Minardi and Tyrrell.
High profile success was quick to follow. Our first victory in Formula Three came in only the third round of our first season  with Paul Stewart Racing’s David Coulthard — with the British, German, Italian and Japanese championships all being won on QUANTUM shocks the following year — and we assisted Dave Cook Racing’s Vauxhall factory backed team to the BTCC manufacturers’ title in ’92 — our first stab at front wheel drive. QUANTUM racing suspension have raced at every level of national and international motorsports including Formula Ford, Formula 3000, Formula Nippon, CART, DTM, NASCAR and Japanese GT — not to mention UK club racing classes including Sports 2000, Super Sports and Mini Miglia.

- Quantum Zero is a range of monotube shock absorbers. No matter which vehicle or how many ways of adjustment, every Zero shock absorber shares the same basic architecture and many of the same components.
- Zero shock absorbers are gas pressurized. The gas and oil are kept separate using a floating piston. This ensures consistent performance with the shock absorber in any orientation.
- Zero shock absorbers are available with up to two ways of external damping adjustment—and all can be opened by a competent individual and re-valved or re-jetted internally.
- A range of pistons allow the shape of the damping curve to be easily tuned. Linear. Digressive. Find your winning formula.
