1K2 race shock absorber for your Chevrolet Nova drag racer from 1961 - 1979

The 1K2 is a ‘high-end’ shock absorber with springs (also known as ‘coil-over’) for demanding street and competition use, that is adjustable in height and damping. It is modular and, apart from the piston rod, entirely composed of high-quality anodised aluminium or, if desired/required, steel. On average, the 1K2 light-alloy shock absorber is 30% lighter than a comparable steel shock absorber. The principle 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 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 much better handling and 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
Due to the larger diameter of the 1K2's piston in comparison with the RSA, the adjustment can be even more refined. Unlike many competitors, Intrax deliberately opts for a single knob for the adjustment of the damping. With this single knob, you can adjust the bump (inward stroke) and rebound (outbound stroke) at the same time, in the proper pre-programmed ratio.

Thermostat
The 1K2 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 of the 1K2 shock absorber is made of high-quality aluminium. This guarantees a low weight, maximum strength and optimal cooling. Whilst designing the 1K2 shock absorber, the largest possible diameter is chosen for 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.

Black Titan

Black Titan was originally developed for the military air force. The air force was looking for something that would make the engines more resistant against the various extreme conditions they are exposed to (sub-zero temperatures, extreme heat, snowstorms, sandstorms, etc.).  Eventually, this led to the development of Black Titan: an extremely hard coating with a very low friction coefficient and corrosion resistant. After applying Black Titan to their aircraft engines, the service interval was sometimes extended with more than 100%.

ARC© (ANTI ROLL CONTROL)

Intrax has developed a unique way to drastically reduce the unwanted role of the car (across width AND length axis). The car drives with the comfort and benefits as if soft springs are mounted. But if a turn is made, braked hard or driven through a pit, ARC checks the row height. So for the street racer no more walking kidneys, but still through the curves and brakes as if a sport chassis has been mounted. And for the rally driver, circuit racer all the benefits of soft springs such as more traction and grip without the disadvantages such as roll, pitch and bounce, jumping the suspension on jumps and or curbs.
