Action Clutch Ironman Unsprung Clutch Kit
2013–2015 Scion FR-S 2.0L DOHC (4U-GSE/FA20) RWD
ACR-1710
Overview:
The Action Clutch Ironman Unsprung Clutch Kit is purpose-built for high-powered race vehicles, delivering exceptional durability and consistent performance under extreme conditions. Designed specifically for the Scion FR-S 2013 to 2015 models equipped with the 2.0L DOHC (4U-GSE/FA20) engine and rear-wheel drive, this clutch kit offers a significant upgrade over the factory setup. It is engineered to handle increased torque loads, making it ideal for track-focused drivers who demand aggressive clutch engagement and reliable power transfer.
This kit is not intended for street use and is best suited for dedicated race applications where maximum holding capacity and quick, precise clutch response are critical. Every kit undergoes rigorous quality checks by experienced engineers to ensure safety and performance consistency, giving racers peace of mind on and off the track.
Key Features:
The Ironman Unsprung Clutch Kit incorporates advanced materials and design elements to meet the demands of competitive motorsports. Key features include:
- 250% increased holding capacity compared to the factory clutch kit
- American Sintered Iron friction material for superior durability and heat resistance
- Dual clamp load heavy-duty pressure plate to maximize torque holding capability
- Aggressive on/off clutch engagement with minimal chatter
- Optimized for rear-wheel drive applications with the FA20 engine
- Engineered specifically for track use and high-performance racing environments
- Light engagement noise and gear rattle may occur due to the unsprung design
- Quality checked and signed off by engineers with over 60 years of collective experience
- Direct fitment for Scion FR-S 2013–2015 models, ensuring straightforward installation
Construction & Design:
The Ironman Unsprung Clutch Kit features a robust construction that prioritizes strength and reliability. The friction disc utilizes American Sintered Iron, a material known for its excellent thermal stability and wear resistance, allowing it to withstand the rigors of high RPM and torque loads without fading. The heavy-duty pressure plate employs a dual clamp load design, which enhances clamp force and torque capacity, ensuring the clutch remains engaged under demanding conditions.
The unsprung design reduces rotating mass, improving throttle response and acceleration. While this design contributes to an aggressive engagement feel, it also means some light noise and gear rattle are inherent characteristics of the kit. This trade-off is acceptable in race environments where performance takes precedence over NVH (noise, vibration, harshness) comfort.
Performance & Sound
The clutch engagement is notably aggressive, providing a sharp on/off feel that allows drivers to modulate power delivery precisely during high-performance driving. This responsiveness is essential for track use, where quick clutch release and engagement can impact lap times and vehicle control. Due to the unsprung nature of the kit, users may experience some light engagement noise and gear rattle, which is typical and expected in race-grade clutch systems.
Installation & Fitment:
This clutch kit is designed as a direct replacement for the factory clutch on Scion FR-S models from 2013 to 2015 with the 2.0L DOHC (4U-GSE/FA20) engine and rear-wheel drive configuration. Installation requires standard clutch replacement procedures and should be performed by a qualified technician familiar with performance drivetrains. No modifications to the transmission or flywheel are typically necessary, but proper break-in and adjustment are recommended to ensure optimal performance and longevity.
It is critical to select the correct clutch kit for your vehicle’s power output to avoid premature failure or transmission damage. If uncertain about compatibility, contacting Action Clutch directly for expert guidance is advised.
