This is a high performance product that has been developed to cope with most installations.
We are a recognised technical agent for Quantum and are able to service and maintain all of their range.
QRS are now one of our recommended performance dampers for a range of vehicles from Escorts to Caterham. We always have an input to the setup and valving required by the customer and this is check by us on our dyno.
Quantum Black is a gas mono-tube damper that has been continually refined since its introduction to F1 in 1989.
20 years of development has seen the original one-piece body and bottom give way to a modular design with a captive floating piston.
With a 14mm shaft to take advantage of modern low-friction seal technology; and an ‘endless’ Ekonol® reinforced PTFE piston ring has replaced Teflon® band guide tape, yielding improved consistency and wear characteristics.
The gas-pressurized mono-tube design tolerates ‘inverted’ operation, the captive floating piston allows BLACK dampers to be easily re-valved without requiring re-pressurisation. Each unit is hand built from the finest quality components and to exacting standards.
All BLACK dampers are fully CNC machined lightweight 6061-T6 aluminium , assembled in house as direct replacements for the original equipment dampers and springs.
Height adjustable via the spring platform for coil over applications.
Bleed past the piston is adjusted by a single ‘clicker’ knob around the top eye through 24 increments or ‘clicks’.
