Designed for Simulation, Gaming & Low-Frequency Immersion
Unlike basic vibration motors or low-quality mono bass shaker kits, this Trak Racer system uses a dedicated 4-channel Class-D amplifier paired with two purpose-built tactile transducers, delivering clean, controlled, low-frequency vibration exactly where you need it.
Sim Racing: engine RPM, exhaust resonance, kerbs, bumps, wheel slip
Flight Simulation: runway rumble, turbulence, touchdown impact
FPS & Gaming: gunfire, explosions, recoil, environmental effects
Music & Media: deep bass you can physically feel
Ideal for titles such as iRacing, Assetto Corsa, Assetto Corsa Competizione, rFactor 2, F1 23 / F1 24, Microsoft Flight Simulator, DCS World, Call of Duty, Battlefield, and other first-person shooter and simulation games.
Quad-Channel Stereo Amplifier
At the heart of the system is the TR-BSA4A-KIT quad-channel Class-D amplifier. With four independent output channels, adjustable low-pass filtering, and 10 W RMS per channel (Peak: 20 W per channel) @ 8Ω, it allows precise tuning of vibration intensity and frequency for realistic tactile feedback.
With a 30–100 Hz frequency response and a 40–100 Hz adjustable low-pass range, the amplifier is optimized for controlled low-frequency effects, delivering balanced power, minimal distortion, and excellent tactile clarity.
Small Power, Big Detail
With a 10W output, these shakers are ideal for control-mounted applications:
- Strong, detailed vibration without overwhelming force
- Low noise compared to large chassis shakers
- Suitable for apartments and shared spaces
- Minimal power requirements and easy to drive with compact amplifiers
When paired with software like SimHub, each shaker can be independently tuned by effect, frequency, and intensity.
Expandable System
The included quad-channel amplifier supports up to four bass shakers. You can optionally expand this system by adding 2 more TR-BSA10 bass shakers( sold separately) to create a four-point tactile feedback system.

Trak Racer Quad-Channel Bass Shaker & Amplifier Kit with Universal Mounting Plates – Simulation Vibration & Immersion System
Experience more immersion with the Trak Racer Quad-Channel Bass Shaker & Amplifier Kit, a premium tactile feedback solution designed to reproduce low-frequency vibration so you can physically feel what’s happening in-game.
What this kit does (and why mount it to your controls): Bass shakers are tactile transducers that convert audio/effects signals into vibration. By mounting them directly to your pedals, shifter, and handbrake, the feedback is delivered exactly where your hands and feet interact with the car—so ABS pulses, wheel slip, drivetrain load, kerb hits, and surface texture feel immediate and precise, instead of being diluted through the seat or cockpit frame.
Transform how your sim rig feels with compact 10W bass shakers, purpose-built to add realistic vibration feedback directly to your pedals, shifter, and handbrake. Instead of sending all vibration through your seat or chassis, these shakers place feedback exactly where your hands and feet interact with the car—for deeper immersion and better control.
Engineered for sim racing, driving simulation, flight simulation, FPS gaming, and music, this system allows you to feel engine and exhaust rumble, kerbs, bumps, runway vibration, turbulence, gunfire, explosions, recoil, and deep bass — one of the most cost-effective upgrades for true simulation immersion.
Designed by simulation specialists since 2008 and trusted through partnerships with the Alpine Formula 1 Team, Porsche, and Airbus Aircraft, this kit reflects motorsport-grade engineering refined for serious simulators.
