Product Description

ACT XACT Lightweight Flywheels are designed to offer the right amount of rotating weight reduction to allow your engine to respond faster, rev easier and provide better acceleration.  ACT has put a lot of time, effort and research into figuring out not only the ideal weight for these flywheels for your specific application, but also where to reduce the weight from to ensure the perfect balance and smoothness from your engine.

ACT offers two types of flywheels.  The Streetlite is a lightweight flywheel that offers the best possible driveability.  The Prolite is lighter than Streetlite but does not offer as smooth driveability due to it's more race focus.  Not all applications are available in Prolite and Streetlite, if available, see below for related products.  For a street only car, we recommend Streetlite, for a street/track car we recommend Prolite.

ACT Flywheel Features:

  • Recommended for both street and track use
  • Can be resurfaced without the need to buy additional parts
  • Chromoly forging which is 3 times more rigid than aluminum
  • Quick throttle response and acceleration
  • Light with low inertia
  • Streetlite offers good driveability
