Atomic by Quantum

The Atomic by Quantum is a high-quality twin-tube shock absorber that conforms to the

requirements of FIA Appendix K. It has a steel body and is available with one or two ways of external adjustment.

Shims on the Piston

Responsible for rebound damping. Rebound adjustment is available on all models. The adjuster is accessible via a window in the top eye or directly from the end of the shaft.

Rubber Mounting Bushes

Adjustable coil-over spring platforms, non-adjustable spring platforms and plain bodies for divorced springs and dampers are all available. 1.9” internal diameter spring hardware is standard and 2.25” spring hardware is optional.

Methods and Materials

The Atomic offers consistent, reliable and legal performance to everyone, as an alternative to OEM parts that are difficult source and often impossible to buy new or service.

PER PERIOD SPECIFICATION

The piston operates inside a central oil filled chamber that is surrounded by a reservoir containing oil and gas at atmospheric pressure.

A base valve controls the flow of oil into the outer reservoir tube during compression. Shims provide a velocity sensitive restriction to flow and external adjustment is by way of a bleed screw.

One-way adjustable dampers have their bump damping set at the factory.

WHY CHOOSE ATOMIC

Atomic shocks offer improved reliability, safety and availability over original components manufactured in period.

In accordance with FIA Appendix K, Atomic shocks contain oil and gas at atmospheric pressure only. It is common practice to seal the gas inside a plastic bladder. Separating the oil and gas in this manner reduces foaming of the oil and improves safety as consistent performance is maintained throughout the duration of a race.

The condition of remanufactured components can vary greatly and performance will vary without a great deal of time, effort and expense. Choosing to buy new shock absorbers that have been designed with a sympathetic eye to the period and its technology ensures no competitive advantage is gained or lost and honours the spirit in which the rules were written.

Atomic shocks are CNC machined from steel bar and tube. Manufacturing from billet on modern machines reduces the requirement for fabricated parts, improving the structural integrity of the damper. The use of high-quality and aerospace materials also benefits safety, considering the age and abuse suffered by road-car-derived components used in period.
