ACT Rigid 4 Pad Clutch Kit

2008–2014 Scion xD

SC1-SPR4

Overview:

The ACT Rigid 4 Pad Clutch Kit is a high-performance upgrade designed specifically for the 2008 to 2014 Scion xD. This kit features ACT’s Sport pressure plate combined with a 4-pad rigid race disc, delivering aggressive engagement and enhanced durability for spirited driving and track use. Ideal for enthusiasts seeking quicker shifts and improved clutch response, this kit balances performance with reliability, making it a solid choice for light to moderate pedal effort applications.

Built to withstand higher clamp loads and heat, the ACT Rigid 4 Pad Clutch Kit offers a noticeable improvement over stock clutches, providing a more direct connection between the engine and transmission. It is engineered to maximize clutch life while maintaining consistent performance under demanding conditions.

Key Features:

This clutch kit incorporates advanced technology and materials to ensure superior performance and longevity:

• Sport pressure plate with exclusive diaphragm design for increased clamp load and reduced deflection
• Four-stage heat-treated diaphragm for enhanced strength and durability
• Precision cover stampings to improve rigidity and consistency
• 4-pad rigid race disc constructed with high-quality ceramic friction materials for excellent heat tolerance
• Chrome-moly heat-treated hub for superior strength and durability
• Lightweight, rigid design promotes quicker shifts and smooth operation
• Harsher engagement suited for aggressive driving and racing environments
• 100% clamp load tested and dynamically computer balanced for reliable high RPM performance
• Extended friction life supported by ACT’s exclusive diaphragm design

Construction & Design:

The ACT Rigid 4 Pad Clutch Kit is engineered with precision and quality materials to meet the demands of performance driving. The Sport pressure plate utilizes an exclusive diaphragm spring design that undergoes a rigorous four-stage heat treatment process, ensuring exceptional clamp load and resistance to fatigue. This design reduces deflection, which helps maintain consistent clutch engagement and extends the overall clutch life.

The 4-pad rigid race disc features ceramic friction materials selected for their high heat tolerance and durability. Its chrome-moly hub is heat-treated to enhance strength, making it capable of handling the stresses of aggressive driving. The lightweight and rigid construction of the disc allows for faster, more precise shifts while minimizing drivetrain shock.

Performance & Sound

This clutch kit delivers a more aggressive engagement compared to stock units, resulting in quicker and more precise shifts. The rigid 4-pad disc design produces a firmer pedal feel and increased gear rattle, characteristics often preferred in racing or high-performance street applications. While engagement is harsher, the trade-off is improved throttle response and clutch control, making it ideal for drivers who prioritize performance over comfort.

Installation & Fitment:

The ACT Rigid 4 Pad Clutch Kit is a direct fit for the 2008–2014 Scion xD, designed to replace the factory clutch without requiring modifications. Installation should be performed by a qualified technician to ensure proper alignment and torque specifications. This kit is recommended for vehicles used in sport or race environments and may not be suitable for daily driving due to its aggressive engagement characteristics.

What's Included:

• ACT Sport pressure plate with exclusive diaphragm design
• 4-pad rigid race ceramic friction disc with chrome-moly hub
• Installation hardware (as required)

Ideal For:

This clutch kit is ideal for Scion xD owners who demand enhanced performance for spirited street driving or occasional track use. It suits enthusiasts looking for quicker shifts, increased clutch clamp load, and improved durability without upgrading to a full race-spec clutch. The kit is best suited for light to moderate pedal effort applications where aggressive engagement and faster response are desired.

ACT (Advanced Clutch Technology) engineers performance clutches and flywheels built for consistent engagement, higher torque capacity, and durability in street and race use. The brand emphasizes quality and reliability and is widely used by enthusiasts who need driveline components that can handle repeated hard launches, shifts, and track abuse.
