Engineered for road and rally racing applications, this flywheel offers a perfect balance of strength, precision, and reduced rotational mass, making it an excellent choice for drivers who want to improve their vehicle’s responsiveness without sacrificing reliability or daily drivability.

Key Features:

The ACT Prolite Aluminum Flywheel stands out with its advanced design and performance benefits, including:

• Lightest flywheel in the ACT lineup, weighing just 9.8 pounds
• Significantly reduced rotational inertia for faster engine revving and improved throttle response
• Super rigid construction for enhanced durability and consistent performance
• Precision CNC machining and dynamic balancing for smooth operation
• Optimized for road and rally racing environments
• Compatible and highly effective when paired with ACT clutch kits
• Designed to maintain excellent drivability despite weight reduction
• Direct bolt-on fitment for 2011–2016 Scion tC, tC2, and xB2 models

Construction & Design:

The Prolite flywheel is crafted from high-grade aluminum, making it significantly lighter than the stock cast iron flywheel. This reduction in weight lowers the engine’s rotational mass, allowing it to rev more freely and respond more quickly to throttle inputs. Despite its lightweight design, the flywheel maintains exceptional rigidity and strength to withstand the rigors of aggressive driving and racing conditions.

Each flywheel undergoes precision CNC machining to ensure exact tolerances and a perfect fit. Additionally, dynamic balancing minimizes vibrations and promotes smooth clutch engagement, contributing to a refined driving experience. The durable aluminum construction also helps dissipate heat more effectively, enhancing clutch longevity.

Performance & Sound

By reducing the flywheel’s inertia, the ACT Prolite Aluminum Flywheel delivers noticeably sharper throttle response and quicker acceleration. Drivers will experience a more immediate engine reaction, which is especially beneficial in performance driving scenarios such as track days or spirited street driving. While the flywheel itself does not significantly alter exhaust sound, the improved engine responsiveness can enhance the overall driving sensation.

Installation & Fitment:

This flywheel is designed as a direct replacement for the stock flywheel on 2011–2016 Scion tC, tC2, and xB2 models, requiring no modifications for installation. Professional installation is recommended to ensure proper torque specifications and clutch alignment. It is highly compatible with ACT clutch kits, which can be installed simultaneously for optimal performance gains.

What's Included:
