Construction & Design:

The ACT Twin Disc HD Race Kit is meticulously engineered using premium materials and advanced manufacturing processes. The clutch discs feature ceramic friction surfaces that provide excellent heat resistance and consistent engagement under extreme conditions. The chrome-moly hub is heat-treated to withstand high torque loads and resist wear, ensuring long-term durability.

The Positive Lift Floater System is a unique design innovation that eliminates common issues such as floater rattle and post wear, resulting in quieter operation and reduced maintenance. The entire assembly undergoes a rigorous four-stage heat treatment on the diaphragms to enhance strength and fatigue resistance, making it suitable for high-performance racing environments.

Performance & Sound

The twin disc configuration effectively doubles the friction surface area, which significantly improves heat dissipation and clutch life. This design allows for aggressive engagement with mild to moderate gear rattle, delivering a race-inspired feel without excessive noise or harshness. Drivers will experience lighter pedal effort and quicker, more precise shifts, enhancing overall driving dynamics and control.

Installation & Fitment:

The ACT Twin Disc HD Race Kit is designed as a direct fit upgrade for Dodge Challenger models from 2008 to 2021, including the SRT8, SRT 392, SRT Hellcat, R/T, R/T 392, Scat Pack, Scat Pack 392, and T/A variants. Installation is straightforward with no major modifications required, as the kit includes a CNC-machined flywheel and alignment tool to ensure proper fitment and ease of installation. Some kits may also include pilot and release bearings for a complete clutch replacement.
