All ACT XACT Flywheels are CNC-machined, heat treated for strength and precision balanced. Substantial material is left behind the clutch surface area for better heat dissipation and durability while weight savings is made where it matters the most for reduced inertia. XACT Flywheels are certified by ACT to meet SFI Spec. 1.1 which makes XACT Flywheels legal for competition when SFI Spec. 1.1 is required or recommended (come complete with official SFI sticker and serial number as required for certification.)

The ACT XACT ProLite flywheels are the lightest XACT flywheels. They provide the best throttle response and lowest inertia. These super rigid flywheels are precision made using high-tech CNC equipment and computer balanced for super smooth high RPM reliability. ACT engineers went through a significant amount of effort to strategically slot XACT ProLite flywheels to lower inertia without sacrificing strength and heat dissipation. ACT XACT ProLite flywheels are recommended for Road and Rally Racing applications.

Key Features:
- Quicker acceleration and increased throttle response
- Maximum gear life - gear will not wear out or fall off
- Serviceable - can be resurfaced with no need to purchased additional parts
- Chrome-moly forgings three times more rigid than aluminum
- Longer lasting because of heat treated friction surfaces
- Excellent heat capacity from retaining adequate material behind the friction surface
- Super rigid trouble-free single piece design
- SFI certified to insure safety
