TECHNOLOGY
Learn more about our semi-active ACE system that regulates the electronic DDA valves inside the shock absorbers to constantly adapt the damping of the suspension.


ACTIVE CONTROLLED ELECTRONICS
Our stand-alone ACE system can be installed in any car that comes without any electronic suspension from the factory.
The control unit and display are powered by the battery of the car. This control unit is placed as close to the center of the car as possible.
Next to the 4 electronic shocks the kit includes:
- TracTive Control Unit (TCU)
- Wiring Harness
- Touchscreen display
DYNAMIC DAMPING ADJUSTMENT
The damping inside each shock absorber is regulated by our patented electronic Dynamic Damping Adjustment (DDA) valve that varies the flow of oil inside the shock absorber.
This electronic valve offers a wide range of damping adjustment and can fully open, fully close or move to any position in between within just 6-10 milliseconds.
Using the data from the G-sensor in the TracTive Control Unit (TCU), the TCU continuously adjusts the individual shock damping by controlling the DDA Valve within milliseconds.
