Construction & Design:

The ACT Twin Disc XT Street Kit is built with precision and durability in mind. The clutch discs utilize premium organic friction materials enriched with copper to optimize heat dissipation and reduce fade during aggressive driving. The steel-backed linings provide exceptional strength to handle high torque loads without compromising reliability.

The chrome-moly hubs are heat-treated to enhance toughness and resist deformation under stress. ACT’s patented Positive Lift Floater System eliminates traditional wear points and rattling noises by removing posts and using a unique floating mechanism. This design innovation contributes to quieter operation and longer service life.

All diaphragms undergo a rigorous four-stage heat treatment process, ensuring consistent clamping force and durability. The kit’s flywheel is CNC-machined and dynamically balanced to guarantee smooth engagement and trouble-free installation.

Performance & Sound

The twin disc configuration provides smooth, progressive engagement with moderate to heavy pedal effort, ideal for street performance applications. The premium organic friction materials offer excellent heat tolerance, reducing clutch fade during high RPM operation. Thanks to the Positive Lift Floater System, the kit operates quietly without the typical rattling sounds associated with twin disc clutches, maintaining a refined driving experience.

Installation & Fitment:

This kit is designed as a direct fit for Dodge Challenger models from 2008 to 2021, covering RT, SRT, and Scat Pack trims. Installation requires standard clutch replacement procedures and includes all necessary components for a complete upgrade. The inclusion of a CNC-machined flywheel and alignment tool simplifies the installation process, ensuring proper fitment and alignment. Some kits may also include a pilot bearing and release bearing, depending on the specific application.

What's Included:

• Pressure plate
• Two clutch discs
• Positive Lift floater
• CNC-machined, dynamically balanced flywheel
• Alignment tool
• Optional pilot bearing and release bearing (varies by kit)

Ideal For:
