2. Key Features
- Durable High-Strength Steel Construction: Crafted from 3MM thick CNC precision laser cut high-strength steel, with the brake load-bearing part thickened to 6mm and pedal panels to 4mm. Processes include laser cutting, polishing, brushing, and electrophoresis.
- High-Precision Sensor Technology: Equipped with advanced load cell components for true linear input measurement of throttle, clutch, and braking force, ensuring precise responses.
- Powerful Processing Unit: Integrates 6 chips, including two independent 32-bit processors and a dedicated 16-bit high-resolution ADC for synchronous signal acquisition. Three fully differential signal amplification chips provide noise immunity, ensuring stable, low-latency, and high-precision signal processing.
- Multi-Dimensional Adjustability: Pedals can be adjusted up, down, left, and right on the base plate. Throttle, brake, and clutch can be independently adjusted for pedal panel height, pedal angle, travel distance, and force curve.
- Dual Bearing Design: Utilizes flange bearings and plane bearings for precise and smooth pedal movement, enhancing realistic feel and feedback.
- Adjustable Resistance Hydraulic Rod: The brake pedal includes an adjustable hydraulic resistance rod with 1-8 levels of adjustment. Hydraulic rods for other pedals are optional.
- Stronger Damping: Brake damping uses 60HA red rubber damping, with extra 80HA and 90HA options for replacement.
- RGB Light Effects: Supports dynamic display of pedal pressure. LED lighting effects are customizable via SIMSONN Manager software, with synchronization across SIMSONN devices.
- SIMSONN Manager Software Support: Allows configuration of non-linear pedal output curves, dead zones, and brake curves. Settings can be saved as profiles for various simulator software.

4. Operating Instructions
4.1. Customizing Pedal Curves and Dead Zones
The SIMSONN Manager software allows for advanced customization of pedal behavior:
- Non-Linear Pedal Output Curves: Adjust the responsiveness of each pedal to your preference, from linear to progressive or aggressive curves.
- Dead Zones: Set minimum and maximum dead zones to eliminate unintended inputs or to fine-tune the pedal's active range.
- Brake Curves: Specifically adjust the brake pedal's response curve for precise braking control.
These settings can be saved as profiles within the software, allowing you to switch between different configurations for various games or driving styles without re-adjusting in-game settings.
4.2. RGB Lighting Control
The integrated RGB lighting provides visual feedback and can be customized through the SIMSONN Manager software. Available lighting modes include:
- Static Color: Choose a single color for constant illumination.
- Breathing: Lights fade in and out.
- Rainbow: Cycles through a spectrum of colors.
- Flowing: Colors flow across the light bar.
- Follow: Lighting dynamically responds to pedal pressure.

5. Maintenance
Regular maintenance ensures the longevity and optimal performance of your SIMSONN PRO X Ultra Pedals.
5.1. Cleaning
- Wipe down the pedal surfaces and frame with a soft, dry cloth.
- Avoid using abrasive cleaners or solvents, as these can damage the finish or internal components.
- Ensure no liquids enter the electronic components or USB connections.
5.2. Component Inspection
- Periodically check all bolts and nuts for tightness. Re-tighten if necessary.
- Inspect the hydraulic rod and springs for any signs of wear or damage.
- Check the rubber damping elastomers for cracks or degradation. Replacement elastomers (60HA, 80HA, 90HA) are provided for customization and wear.
