200 proof QUANTUM. The perfect example of form follows function.
When we were challenged to produce an affordable shock for one-make race series and the aftermarket, there was one area in which we were unwilling to compromise: quality. And the way we see it, the only way to guarantee that is to keep design and manufacture in house. All QUANTUM ZERO shocks are manufactured at our premises in Sussex, with the bare minimum of sundry items bought in from established suppliers in the United Kingdom and Europe.
Keep it simple, stupid.
ZERO shock bodies are thread cut to allow preload adjustment of the road spring. The female thread form also appears inside the shock bottom. This means the same thread can be used for spring preload adjustment and assembly, reducing tooling costs and time spent on the machine.
Similarly, the pressure fitting and its o-ring seal are concealed beneath a spherical joint. This allows the fitting to be quickly and easily turned on the lathe and the number of component parts is reduced — but it also means the joint can protect the fitting from the elements and ensure the long-term integrity of the seal.
Fixed bleed. Optimum valving. Zero adjustment. Zero fuss.
ZERO shocks are only available as original equipment and through selected retail partners. We work closely with our distributors to provide them with a product that is perfectly valved to suit the requirements of their customers — so you can be sure your car is realizing its full potential, right out of the box. And because there’s no adjuster mechanism to pack with road dirt and grime, that’s one less point of failure to worry about.
Low friction. Consistent performance.
The benefits of fixed bleed aren’t limited to reduced complexity and improved durability. Because no adjuster rod passes up the middle of the shaft, the shaft diameter can be reduced to 12mm without compromising integrity. Reducing the shaft diameter reduces friction at the seal pack and the volume of fluid displaced. And less displaced fluid means less floating piston travel — yet again reducing friction and change in gas pressure throughout the operating stroke.
