Action Clutch Stage 4 Clutch Kit

1987–1992 Toyota Supra 3.0L (7MGTE) Turbo R154

Part #: ACR-2149

Overview

The Action Clutch Stage 4 Metallic Rigid Clutch Kit is designed for Toyota Supra enthusiasts seeking maximum performance and durability. Built to handle high horsepower and aggressive driving conditions, this clutch kit offers a significant upgrade over stock components, ensuring your vehicle can support increased power levels while maintaining reliable engagement. Whether you're building a high-performance street car or a dedicated track machine, this clutch provides the grip and heat dissipation needed for spirited driving and consistent performance.

Engineered for drivers who demand aggressive engagement and rapid heat dissipation, the Stage 4 clutch features a heavy-duty ceramic system that delivers outstanding holding capacity. Its lightweight, unsprung hub ensures minimal rotational mass, resulting in quicker throttle response and reduced drivetrain shock. The clutch pedal feel remains relatively light despite its aggressive engagement, providing a confident driving experience without excessive pedal effort. This makes it suitable for daily driving combined with high-performance applications.

Key Features

This clutch kit incorporates several advanced features to optimize performance and durability:

• Single diaphragm heavy-duty pressure plate: Provides robust clamping force to handle increased power and torque, supporting up to 170% more holding capacity than stock units.
• Rigid ceramic clutch system: Utilizes high-quality ceramic friction material for excellent heat resistance and durability under demanding conditions.
• Lightweight unsprung hub: Ensures rapid engagement and minimal rotational inertia, improving throttle response and acceleration.
• Reinforced drive straps: Enhance durability and prevent deformation during aggressive shifts and high-stress driving.
• Rapid heat dissipation: Designed to manage the high temperatures generated during spirited driving or racing, reducing the risk of clutch fade.
• Aggressive engagement: Facilitates quick power transfer from the engine to the drivetrain, ideal for performance applications.
• Pedal feel: Maintains a relatively light pedal pressure for ease of use, despite its high clamping force.

Construction & Design

The Action Clutch Stage 4 clutch kit features a meticulously engineered design focused on strength and heat management. The ceramic friction material is bonded to a rigid metallic backing, providing a stable and reliable interface that withstands high torque loads. The pressure plate is constructed from heavy-duty steel with reinforced drive straps, ensuring long-lasting performance even under extreme conditions. The hub assembly is lightweight and unsprung, reducing rotational mass and enhancing throttle response. All components are precision-machined and assembled to exact specifications, ensuring a perfect fit and smooth operation.

Installation & Fitment
