Part #: SB13-HDG4

Overview

The ACT HD/Race Sprung 4 Pad Clutch Kit is a high-performance clutch solution designed for enthusiasts seeking improved response and durability in their sports cars. Compatible with the Toyota 86, Subaru BRZ, and Scion FR-S from 2013 to 2020, this kit is ideal for drivers who demand a reliable, aggressive engagement for spirited driving or track use. The kit combines a heavy-duty pressure plate with a race-oriented clutch disc, offering a balance of increased clamp load, reduced deflection, and faster shifting capabilities. Engineered to withstand harsh conditions, this clutch kit enhances your vehicle’s performance while maintaining smooth operation and longevity.

Key Features

This clutch kit features several advanced design elements aimed at maximizing performance and reliability:

• Heavy Duty pressure plate with exclusive diaphragm design for increased clamp force
• Four-stage heat-treated diaphragm for superior durability and heat resistance
• Precision cover stampings to ensure rigidity and consistent engagement
• 4-pad spring-centered race disc to dampen torsional vibrations and reduce noise
• Spring retainers with wraparound spring windows for enhanced spring support and stress reduction
• Harsher engagement for quicker shifts, ideal for performance driving
• Designed for smaller disc sizes suitable for smaller engines in the specified models

Construction & Design

This clutch kit is built with high-quality materials, including a robust pressure plate and a spring-centered race disc. The components undergo a four-stage heat-treating process, ensuring maximum strength and heat dissipation. The precision stampings and thicker retainers contribute to the overall rigidity and reliability, making it suitable for demanding driving conditions.

Driving Feel & Feedback

The clutch provides a firm, responsive engagement that enhances driver control during aggressive driving or track sessions. The spring-centered disc dampens torsional vibrations, resulting in quieter operation and smoother shifts, even under high stress.

Installation & Fitment

Installation requires standard mechanical skills and tools. Proper alignment and torque specifications should be followed to ensure optimal performance and longevity. This kit is a direct replacement for the stock clutch components in compatible vehicles.

What’s Included

The package includes the heavy-duty pressure plate, race disc, and necessary hardware for installation, providing everything needed for a complete upgrade.
