Quantum One.Zero Dampers for Mazda RX8

Quantum Zero One single adjustable dampers for Mazda RX8 models. 

When Quantum 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 they see it, the only way to guarantee that is to keep design and manufacture in house. All QUANTUM ZERO shocks are manufactured at their premises in Sussex, with the bare minimum of sundry items bought in from established suppliers in the United Kingdom and Europe.

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.

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.
