JRZ PROactive

The JRZ PROactive suspension is an advanced electronic damping system designed to provide real-time, adaptive control for street, track, and off-road applications. Unlike traditional passive dampers that use fixed valving, the PROactive system utilizes an ultrafast electronic valve that adjusts damping characteristics instantly to manage both driver inputs and road disturbances. 

Core Technology: The MFC Valve
At the heart of the system is the patent-pending Multi-Function Control (MFC) valve. 
Ultrafast Operation: Reacts significantly faster than standard factory electronic valves (like Porsche’s PASM), ensuring optimal tire contact and stability.

Simplified Design: Features only one moving part and is dynamically lubricated for a maintenance-free, lifelong operation.

Bi-directional Flow: Provides precise damping control in both compression and rebound strokes.

System Variants
The PROactive line is offered in two main configurations to suit different vehicle needs: 
Plug & Play (DPi): Designed as a direct replacement for factory electronic dampers (e.g., Porsche PASM). It plugs into original connectors and retains factory dashboard controls and driving modes while providing superior response.

Stand-Alone: A complete system for vehicles without factory electronic suspension. It includes a Valve Control Unit (VCU) that processes data at 1000Hz from 3-axis acceleration and gyro sensors to adjust the dampers automatically. Settings can be tuned wirelessly via a Bluetooth-connected smartphone app. 

Performance Benefits
Dynamic Stability: Continuously self-adjusts during braking, cornering, and acceleration to minimize body roll and pitch.

Improved Traction: By controlling the un-sprung mass (wheels, tires, and brakes) more effectively, the system maintains a better contact patch on uneven surfaces.

Versatility: Allows a single setup to handle daily driving comfort and aggressive track-day performance without manual adjustment between sessions.
