2K2
The 2K2 is a
‘high-end’ 2-way system (bump and rebound separately adjustable) shock absorber with springs (also known as
‘coil-over’) for demanding track day and competition use, that is
adjustable in height and damping and always comes with an external reservoir. It is modular and, apart from the
piston rod, entirely composed of high-quality anodised aluminium with
external reservoirs. On average, the 2K2 light-alloy shock absorber
is 30% lighter than a comparable steel shock absorber. It is based on
the same technology that has helped Schumacher become a World
Champion.
If it involves a
Macpherson suspension, the absorber will feature a design with a 45mm
Ø (52mm for the XL version) upside down insert. This upside-down
design delivers a much higher installation rigidity (less
flexibility) to the Macpherson suspension. This higher installation
rigidity results in a much better handling and a more direct steering
behaviour.
Setting
All
shock absorbers that Intrax manufactures are custom-built. This means
the shock absorbers will only be manufactured once the specific data
of the car (tyre type, use of the car, any adjustments made to the
car, etc.) and the driver's wishes are known. Based on these data,
the engineers calculate/design the ideal shock absorber, which will
then be manufactured.
Adjustable
damping
Because of the second knob for the settings and the
external reservoir, the 2K2, in comparison with the 1K2, can be
adjusted in an even more refined way. For example, the 2K2 allows for
an independently adjustable bump (inward stroke of the shock
absorber) related to the rebound (outward stroke of the shock
absorber). The knob to adjust the bump is located on the external
reservoir. The independently adjustable bump and rebound in
combination with an external reservoir makes the 2K2 the ideal shock
absorber for the demanding competition (track day) driver, who wants
to remain in full control.
Thermostat
The
2K2 damper is fitted with an internal thermostat. The thermostat
keeps the damping constant at varying temperatures. This means the
damping and driving behaviour remain exactly the same at various
operating and ambient temperatures.
Large
diameters
Where possible, the
housing and the external reservoir of the 2K2 shock absorber are made
of high-quality aluminium. This guarantees a low weight, maximum
strength, optimal cooling and large volumes because of the external
reservoir. Whilst designing the 2K2 shock absorber, the largest
possible diameter is chosen for an even more accurate damping
control; usually a 52mm housing with 46mm piston. Where possible,
Macpherson struts are fitted as upside-downs with a 45mm (52mm for
the XL version) diameter instead of a thin piston rod that is mounted
to the chassis.
