2006–2015 Honda Civic 1.8L SOHC (R18)

Part #: ACR-0675

Overview

The Action Clutch Stage 4 Metallic Rigid Clutch Kit is designed for Honda Civic owners seeking enhanced performance and durability. Whether you're a spirited street driver, a track enthusiast, or someone who demands more from their daily driver, this clutch kit offers a significant upgrade over stock components. Built with high-quality materials and engineered for aggressive engagement, it provides the reliability and performance needed for demanding driving conditions.

This clutch kit is ideal for those looking to support increased horsepower and torque, especially in modified or heavily driven Civics. Its aggressive engagement and rapid heat dissipation help ensure consistent performance during spirited driving sessions or extended track days. The lightweight, unsprung hub design reduces rotational mass, contributing to quicker throttle response and improved overall vehicle responsiveness. With a slight increase in pedal pressure, it strikes a balance between streetability and high-performance capabilities, making it suitable for daily use while still delivering race-inspired performance.

Key Features

The Action Clutch Stage 4 Clutch Kit incorporates several advanced features to maximize performance and durability:

• Heavy-Duty Ceramic Clutch System: The single diaphragm pressure plate uses high-quality ceramic material, providing outstanding heat resistance and increased holding capacity, rated at 170% more than stock. This ensures the clutch can handle higher power levels without slipping.
• Lightweight Unsprung Hub: The unsprung hub design reduces rotational inertia, allowing for quicker engine response and smoother engagement, which is especially beneficial during aggressive driving or racing conditions.
• Reinforced Drive Straps: The reinforced drive straps enhance durability and longevity, ensuring the clutch maintains performance over extended use and under high-stress conditions.
• Aggressive Engagement: The clutch features a slightly aggressive engagement point, providing a more direct connection between the pedal and the drivetrain for better control and feedback.
• Rapid Heat Dissipation: The high-quality ceramic material and design help dissipate heat quickly, reducing the risk of clutch fade during intense driving sessions.
• Pedal Feel: Despite its high-performance capabilities, the pedal feel remains relatively light, offering a good balance between ease of use and performance.

Construction & Design

The Action Clutch Stage 4 Clutch Kit is constructed with precision and durability in mind. The heavy-duty pressure plate features a single diaphragm design, which provides a robust clamping force necessary for high-horsepower applications. The ceramic friction material is engineered for excellent heat resistance and consistent engagement, even under extreme conditions. The reinforced drive straps add structural integrity, preventing deformation or failure during aggressive use.

The kit's components are designed for straightforward installation, with all parts engineered to fit seamlessly into the OEM clutch housing. The use of high-quality materials ensures long-lasting performance, making this clutch kit a reliable upgrade for enthusiasts pushing their Honda Civic to the limit.
