TS6-HDR4

Overview:

The ACT Race Rigid 4 Pad Clutch Kit is a high-performance clutch solution designed specifically for the 2004 to 2006 Scion xA and xB models. Engineered for racers and enthusiasts seeking aggressive engagement and quicker shifts, this kit combines durability with precision to handle demanding driving conditions. Featuring ACT’s most popular Heavy Duty pressure plate and a rigid 4-pad race disc, it delivers enhanced clamp load and consistent performance for spirited street driving and track use.

This clutch kit is ideal for drivers who want a reliable upgrade that improves throttle response and shift speed without sacrificing clutch life. It is especially suited for smaller engines where a smaller disc size is necessary, providing a balance of performance and durability.

Key Features:

Designed with advanced technology and quality materials, the ACT Race Rigid 4 Pad Clutch Kit offers the following key benefits:

• Heavy Duty pressure plate with exclusive diaphragm design for increased clamp load and reduced deflection
• Four-stage heat-treated diaphragms for superior strength and longevity
• Precision cover stampings to enhance rigidity and maintain consistent performance
• 4-pad rigid race disc constructed with high-quality ceramic friction materials for excellent heat tolerance
• Heat-treated chrome-moly hub for enhanced strength and durability under high stress
• Lightweight, rigid disc design enabling faster, smoother shifts and trouble-free service
• Aggressive engagement with moderate pedal effort, ideal for race and performance driving
• 100% clamp load tested and dynamically computer balanced for smooth operation at high RPM
• Extended friction life supported by ACT’s exclusive diaphragm design

Construction & Design:

The ACT Race Rigid 4 Pad Clutch Kit is meticulously engineered for maximum performance and durability. The Heavy Duty pressure plate features a unique diaphragm spring design that increases clamp load while minimizing deflection, which helps extend clutch life and maintain consistent engagement. Each diaphragm undergoes a rigorous four-stage heat treatment process to ensure exceptional strength and reliability under extreme conditions.

The clutch disc itself is built with a rigid 4-pad ceramic friction material that offers high heat resistance and aggressive engagement characteristics. The chrome-moly hub is heat-treated to withstand the stresses of racing and high-performance driving, providing long-lasting durability. The lightweight design reduces rotational mass, allowing for quicker throttle response and faster shifts.

Performance & Sound

This clutch kit delivers a harsher engagement compared to stock setups, which translates to faster and more precise shifts favored in racing scenarios. Drivers can expect increased gear rattle typical of rigid disc designs, which is a trade-off for the enhanced performance and quicker clutch response. Pedal effort remains light to moderate, making it manageable for daily driving while still offering aggressive engagement for spirited use.

Installation & Fitment:

The ACT Race Rigid 4 Pad Clutch Kit is a direct fit for 2004 to 2006 Scion xA and xB models, designed to replace the factory clutch without requiring modifications. Installation should be performed by a qualified technician to ensure proper alignment and optimal performance. The kit is recommended for race use only due to its aggressive engagement characteristics and potential for increased spline wear.
