The Science Behind the Act Clutch: Understanding How It Works – 2024 Guide.

A manual gearbox setup depends on the clutch, which transmits the force from the engine to the tires. Many car enthusiasts use the ACT clutch, the best alternative performing clutch, to boost the efficiency of their automobiles. A high-performance, called an “ACT clutch,” is intended to manage more force and power than a regular can.

Compared to a standard grip, an ACT clutch often has durable substances, more aggressive gripping materials, and a more robust design. This enables it to operate perfectly, stay longer, and be more dependable even under challenging circumstances. If you want to replace the clutch in a high-performance car or if you participate in racing or other high-performance driving activities, an ACT clutch might be a good option.

The Functions Of A Clutch


To know how the ACT clutch functions, we must first understand how a clutch works.

Anyone can change gears by separating the engine from the transmission using a clutch.

When the clutch is released, the transmission transfers the engine’s force to the tires, propelling the vehicle forward. When the clutch is released, the driver can change speeds without worrying about causing transmission damage because the engine’s force is cut off from the gearbox.

The primary parts are the flywheel, pressure plate, and clutch disc.

  • The engine spins with the flywheel linked to it.
  • The pressure plate, combined with the flywheel, forces the clutch disc.
  • The pressure plate and flywheel are sandwiched by the clutch disc attached to the transmission.

The pressure plate is released, and the disc disconnects from the flywheel when the pedal is depressed. Doing this allows the driver to change gears because the engine’s power is separated from the gearbox. When the pedal is released, the engine’s power is transferred to the transmission and the wheels because the pressure plate presses down on the disc, engaging the flywheel.

What Is The ACT Clutch’s Mechanism?

The ACT clutch has been modified to enhance performance like a standard one. The heavy-duty pressure plate the ACT clutch uses applies more clamp pressure to the disc than a regular pressure plate. Because of its enhanced clamping force, high-performance applications can manage more power and torque.

Another component of the ACT clutch is the disc, composed of superior materials like ceramic or carbon that can withstand higher temperatures and friction. Also, compared to a typical disc, these materials offer a firmer grip, enhancing the clutch’s ability to transfer power.

The ACT clutch utilizes a lightweight flywheel to reduce rotational mass and improve engine speed range. This enhances acceleration and speed responsiveness while lowering engine strain and damage.

A smooth, disciplined drive technique and awareness of the clutch engagement are the keys to controlling your vehicle’s speed when using an ACT clutch. You’ll be able to master your vehicle’s performance and take advantage of an enhanced clutch with time and effort.

ACT Clutch Parts.


This comprises six components that combine and strengthen the gearbox so it works effectively. The components are as follows:

Pressure Plate

The pressure plate is the main component that forces the disc to hold and disable the engine’s power from the gearbox. The ACT pressure plate is more potent than a standard one and exerts more compressive force on the disc.

Clutch Disc

It transmits power from the engine to the gearbox and is situated between the pressure plate and the flywheel. High-quality substances, such as ceramic or carbon, make the disc because they can withstand higher temperatures and friction while offering sturdy grip and more effective power transfer.


The motor rotates with the flywheel linked to it. The ACT flywheel is lightweight, reducing rotational mass and allowing the engine to work more freely. This improves throttle response and acceleration and reduces engine stress and damage.

Release Bearing

The release bearing is a small bearing that applies pressure to the pressure plate’s fingers when the pedal is released, disengaging the engine’s power from the gearbox.. The ACT release bearing is designed to handle the increased clamping force of the heavy-duty pressure plate.

Pilot Bearing/Bushing

The pilot bearing or bushing supports the transmission input shaft and helps align it with the engine’s shaft. The ACT pilot bearing or bushing is designed to improve stability and compatibility.

Alignment Tool.

The alignment tool is used during installation to see that the disc is correctly aligned with the flywheel and pressure plate.

The Science Behind ACT Clutch


The ACT clutch’s science is founded on force and friction. By having a heavy-duty pressure plate that applies more clamping force to the disc and allows it to transfer more power to the transmission, the ACT clutch manages more horsepower and torque than a regular one.

By applying pressure to the pressure plate’s fingers when the pedal is depressed, the release bearing disconnects the engine’s power from the transmission. The pressure plate pushes on the disc when the pedal is let go, transferring power from the engine to the transmission.

The clamping force of the pressure plate is crucial to how well the ACT clutch works. The ACT pressure plate is heavier and applies more clamping force to the clutch disc than a regular one. The clutch can manage greater power and torque due to the higher clamping force, improving grip and power transfer.

Another vital part of the ACT clutch is the clutch disc. High-quality materials, such as ceramic or carbon, make the ACT disc, which can withstand higher temperatures and friction than a standard disc. This improves grip and permits more effective power transfer.


The ACT clutch is a fantastic improvement to consider if you want to increase your car’s performance. Friction and force are the foundation of this. The ACT clutch is a well-liked upgrade choice for auto enthusiasts looking to boost their vehicle’s performance. It utilizes a heavy-duty pressure plate, premium clutch disc, and lightweight flywheel and offers better grip, increased clamping force, improved acceleration, and reduced engine stress and damage.

When car enthusiasts want to boost their vehicle’s performance, they frequently choose this. It is a fantastic option for high-performance driving since it offers better grip, more clamping force, and improved acceleration.
