Action Clutch Stage 4 Clutch Kit

1990–1999 Mitsubishi Eclipse GST 2.0L DOHC 4G63T Turbo 2WD

Part #: ACR-1062

Overview

The Action Clutch Stage 4 Metallic Rigid Clutch Kit is designed for Mitsubishi Eclipse GST models from 1990 to 1999 equipped with the 2.0L DOHC 4G63T turbo engine. This high-performance clutch kit is ideal for enthusiasts seeking aggressive engagement, increased holding capacity, and reliable durability for spirited driving, street performance, or track use. Whether you're upgrading for better power transfer or enhanced durability under demanding conditions, this clutch kit delivers exceptional performance to support your driving goals.

Built with a focus on aggressive engagement and heat dissipation, the Stage 4 clutch provides a significant upgrade over stock components. Its lightweight, unsprung hub ensures rapid response and minimal rotational mass, helping you achieve quicker throttle response and improved acceleration. The kit's reinforced pressure plate and ceramic friction material work together to handle increased power levels while maintaining a pedal feel that remains manageable for daily driving. This combination makes it suitable for drivers who demand both streetability and high-performance capability from their Mitsubishi Eclipse.

Key Features

The Action Clutch Stage 4 Clutch Kit incorporates advanced materials and engineering to deliver superior performance and durability. Key features include:

• Heavy-Duty Ceramic Friction Material: The ceramic friction surface provides excellent heat resistance and high torque capacity, making it suitable for turbocharged applications and aggressive driving styles.
• Single Diaphragm Heavy-Duty Pressure Plate: Reinforced drive straps and a robust design ensure consistent clamping force and long-lasting durability under high-stress conditions.
• Lightweight Unsprung Hub: Reduces rotational inertia for quicker throttle response and smoother engagement, especially beneficial during high-rev shifts.
• Rapid Heat Dissipation: Designed to handle the increased heat generated during spirited driving or racing, helping to maintain clutch integrity and performance over time.
• Aggressive Engagement: The clutch engages quickly and firmly, providing a more direct connection between the pedal and the drivetrain for precise control.
• Pedal Feel: Despite its aggressive nature, the clutch maintains a relatively light pedal pressure, ensuring comfortable operation during daily use.

Construction & Design

The Action Clutch Stage 4 kit features a meticulously engineered design focused on durability and performance. The ceramic friction disc is constructed with high-quality materials capable of withstanding extreme heat and stress, making it ideal for turbocharged engines and high-horsepower setups. The pressure plate is a single diaphragm design, reinforced with drive straps to prevent fatigue and ensure consistent clamping force. The entire assembly is built with precision to fit seamlessly into the factory clutch housing, providing a bolt-on upgrade without the need for modifications.

The use of a lightweight, unsprung hub reduces rotational mass, which translates into quicker throttle response and less drivetrain inertia. The heat dissipation features help prevent clutch fade during aggressive driving or repeated launches, ensuring reliable performance over time. The kit's components are TIG-welded and CNC-machined for exact fitment and durability, making it a trusted choice for performance-minded drivers.

Installation & Fitment

This clutch kit is a direct bolt-on replacement for the factory clutch in Mitsubishi Eclipse GST models from 1990 to 1999 with the 2.0L DOHC 4G63T turbo engine. No cutting, drilling, or extensive modifications are required for installation. Basic mechanical skills and standard tools are sufficient to complete the swap. It is recommended to inspect and replace the release bearing and pilot bearing during installation to ensure optimal performance and longevity. Proper break-in procedures should be followed to maximize the lifespan and performance of the new clutch components.
