T2R-D03

Overview:

The ACT Twin Disc XT Race Kit is a high-performance clutch solution designed specifically for Dodge Challenger models from 2008 to 2021, including RT, SRT, and Scat Pack variants. Engineered for racers and enthusiasts seeking enhanced durability and superior engagement, this twin disc kit offers twice the friction surface area compared to traditional single disc clutches. This results in improved wear resistance, greater heat capacity, and extended service life, making it ideal for aggressive driving and track use.

With its advanced design and robust construction, the ACT Twin Disc XT Race Kit delivers consistent, reliable performance under demanding conditions, ensuring quicker shifts and a more responsive driving experience.

Key Features:

Built to meet the needs of performance drivers, the ACT Twin Disc XT Race Kit incorporates several innovative features:

• Proprietary Positive Lift Floater System for quiet operation without floater rattle or post wear
• Exclusive four-stage heat treatment on all diaphragms for enhanced durability
• Adjustable design to compensate for disc wear and ensure equal disengagement of both discs
• High-quality ceramic friction material on 6-pad rigid race discs for aggressive engagement
• Heat-treated chrome-moly hub for superior strength and longevity
• Lightweight, rigid construction promotes quicker shifts and trouble-free service
• Includes a CNC-machined, dynamically balanced flywheel for smooth operation at high RPMs
• Torque capacity of 1,263 ft/lbs, representing 168% over the original equipment clutch
• Disc diameter of 10.5 inches (267 mm) with a 1.125-inch input shaft diameter
• Meets SFI 1.2 safety standards for racing applications

Construction & Design:

The ACT Twin Disc XT Race Kit is engineered with premium materials and precision manufacturing techniques. The clutch discs feature ceramic friction surfaces that provide excellent heat resistance and consistent performance under heavy loads. The chrome-moly hub is heat-treated to maximize strength and durability, ensuring the kit withstands the rigors of aggressive driving and racing conditions.

The Positive Lift Floater System eliminates common issues such as floater rattle and post wear, resulting in quieter operation and longer component life. The entire assembly is designed to be lightweight yet rigid, reducing rotational mass and enabling faster engine response and smoother shifts.

Performance & Sound

This twin disc kit delivers moderate to heavy pedal effort with aggressive engagement, making it well-suited for drivers who demand precise control and quick throttle response. The doubled disc surfaces improve heat dissipation, reducing the risk of clutch fade during extended high-performance use. Additionally, the dynamically balanced flywheel ensures smooth operation at high RPMs, minimizing vibrations and enhancing drivetrain reliability.
