Custom Damping System
The upgraded damping material offers enhanced elasticity and durability. Three dampers with different hardness levels provide excellent compression response and precise force feedback (kg) under various pedal pressures, delivering a more realistic and controllable sim-racing pedal feel.

The damping block set includes 10 spacers, allowing flexible combinations to achieve various brake pedal feels for different vehicle types. The more damping blocks you install, the longer the pedal travel; conversely, fewer damping blocks result in a shorter pedal stroke.
SIMSONN Progressive Rubber Damper & Coil Spring — Real Supercar Brake Feel up to 60kg
The SIMSONN brake pedal damper kit combines interchangeable rubber damping blocks (19mm, 28mm and 37mm) with a precision coil spring to deliver a progressive force curve that reaches up to 60kg of pedal force — closely replicating the firm, nonlinear brake feel of high-performance cars and supercars. The softest combination ships as the factory default, so beginners can drive straight out of the box, while advanced sim racers can swap in firmer dampers to fine-tune pedal travel and bite point for their load cell or hydraulic simulator pedals
Dual-Stage Brake System
The brake pedal adopts a dual-stage design consisting of a rubber damper and a coil spring, faithfully reproducing the feel of real-car braking.
Two-Stage Braking Mechanism — Coil Spring Pad Gap & Rubber Damper Bite Force
The SIMSONN sim racing brake pedal uses a realistic two-stage compression design. In Step 1, the coil spring compresses to simulate the natural gap between the brake pads and brake disc; in Step 2, the rubber damper engages to replicate the firm main braking force applied to the disc — giving you authentic bite-point feedback for trail braking and threshold braking. A 10mm spacer is pre-installed inside the coil spring to shorten compression travel for a stiffer pedal feel; simply remove it for longer, softer travel, or replace the spring entirely with the spacer for maximum firmness.

SIMSONN Plus X | SIMSONN Pro X Ultra Software — Customizable Pedal Vibration Feedback for ABS, Traction Control & Clutch
The free SIMSONN Plus X | SIMSONN Pro X Ultra tuning software gives you full control over your sim racing pedal feedback. Each of the three pedal motors — throttle, brake and clutch — can be independently configured with realistic telemetry-driven vibration effects, including ABS pulsation, traction control (TC) intervention, wheel lock, wheel slip, gear shift and RPM cues. Fine-tune every effect with adjustable vibration strength and frequency (e.g. 77% ABS strength at 50Hz), plus a clutch bite-point ratio range, so you feel exactly when the tires lock, the rear steps out, or the clutch engages — immersive, data-rich feedback that works seamlessly with load cell pedals and major sim racing titles. Profiles can be saved, imported and reverted in one click for different cars and tracks.
SIMSONN Manager Software allows for precise adjustment of vibration frequency and intensity, enabling you to replicate the driving sensations of various vehicles.
Precision Engineered
Structure
All pedals are assembled with high-standard components, ensuring a solid and durable structure that delivers an exceptional racing experience.
Dual-bearing design
enhances flexibility and stability
during pedal movement.
Dual-Bearing Design — Precision Pivot Bearings for Zero-Friction Pedal Travel
Every SIMSONN sim racing pedal is built on a precision dual-bearing design, with two dedicated bearing points per pedal to eliminate the slack, bind and squeak found on bushing-style pivots. At the main pivot, a ball bearing handles the rotational load with near-zero friction while a thrust bearing absorbs the axial side-force generated under hard braking; a flanged bearing at the secondary mount keeps the shaft perfectly aligned and prevents lateral play. The result is a silky, consistent stroke that stays smooth and precise through thousands of braking cycles — so your brake modulation and threshold braking remain accurate lap after lap on load cell and hydraulic simulator pedals.

comfort and reduced noise.
Authentic Hydraulic Damping System
Pro X Ultra pedals come pre-installed with hydraulic rods, significantly enhancing the smoothness of pedal operation. The throttle pedal is equipped with a one-way hydraulic rod, the brake pedal features an 8-stage adjustable hydraulic rod, and the clutch pedal utilizes a two-way hydraulic rod, delivering an exceptionally realistic hydraulic feel that closely mimics actual racing braking feedback.
Inside the SIMSONN Hydraulic Damper — Piston, Hydraulic Oil & Adjustable Damping Force
This cutaway reveals what makes the SIMSONN hydraulic sim racing pedals feel so authentic. Inside each high-precision reinforced hydraulic cylinder, a precision piston pushes through hydraulic oil, creating the linear, pressure-sensitive resistance of a real car's master cylinder — sealed at both ends by a rubber seal and oil seal to prevent leaks over years of use. The hydraulic rod rides on a lubricated smooth travel rod with precision alloy joints for friction-free movement, while the integrated coil spring and a built-in damping force adjuster let you dial the exact firmness you want — from light street-car feel to stiff GT3/prototype braking — making it the most tunable hydraulic brake and clutch pedal system in its class.
Freely Customizable for a Truly Authentic Experience
The throttle, brake, and clutch pedals can each be adjusted to multiple positions, allowing you to create the perfect personalized setup to suit your preferences.

Comprehensive Adjustment System
With precisely engineered mechanisms and adjustable components, the pedals can be customized to match your driving style — from casual simulation to professional racing performance.
SIMSONN Gear Shifter Force Curves — Red, Blue & Yellow Springs with Tunable Shift Resistance
Dial in your perfect shift feel with the SIMSONN sim racing gear shifter and its fully tunable gear force curve. Three interchangeable springs — Red (firm, up to ~20kg), Blue (medium) and Yellow (soft, ~6kg) — reshape the concave resistance curve for both top gear (maximum concave) and middle gear (medium concave), so you can replicate anything from a light street H-pattern gate to a heavy notched race dog-box. Finer tuning comes from the 2.0mm and 1.5mm spring preload settings, each offering maximum, moderate and minimum force levels across the full 75mm lever travel — giving crisp, positive shifts with the exact notch weight and feedback you want for your H-pattern or sequential shifter.
Adjustable Pedal Surface Angle
Each pedal allows adjustment of both panel height and angle to suit different foot sizes. The front offers two height levels (15 mm apart), while the rear allows fine-tuning—helping you achieve optimal comfort.
Adjustable Pedal Angle
Each pedal supports angle adjustment to match your seat position and setup. The pedal angle can be changed by adjusting the rear mounting studs. The factory default is Level 1 (approximately 9° backward tilt), with three levels available and up to 6° forward tilt.

Adjustable Pedal Force Curve
The throttle and clutch pedals support adjustment of pedal resistance, which also changes the output force curve.Adjustment can be made by moving the slider on the pedal arm.Unlike the throttle pedal, the clutch pedal requires two adjustment points, and these two devices must be positioned in opposite slots.When the slider is set to the highest position, greater force is required to reach the pedal’s maximum travel, and the overall resistance slightly increases.
Adjustable Pedal Angle
Each pedal supports adjustable travel. By moving the blue limiter, you can easily change the total pedal stroke range.
