Description

The ACT Prolite Flywheel (Part Number 600170) is a lightweight, high-performance upgrade engineered to deliver maximum engine responsiveness and acceleration for Subaru and Saab performance models. Designed with the lowest inertia in ACT’s lineup, it’s ideal for road racing, rally, and other competition settings where rapid throttle response and precise control are critical.

Crafted from heat-treated forged steel, the Prolite Flywheel combines exceptional strength and heat tolerance with a one-piece design that minimizes failure points and ensures uniform heat transfer from the clutch disc. The induction-hardened ring gear provides extended durability, while CNC machining and dynamic balancing guarantee smooth, vibration-free operation across the full RPM range.

This flywheel enhances driveline efficiency, reduces gear rattle, and delivers a sharper, more direct driving feel. Fully serviceable and resurfaceable without additional parts, it’s built for long-term performance and reliability. Compatible with a range of Subaru and Saab models—including the 2002–2004 Impreza, 2004 Baja and Forester, and 2005 Saab 9-2X—the ACT Prolite Flywheel is the perfect solution for enthusiasts seeking professional-grade response and durability.

Features:

  • Lightweight design with lowest inertia for improved throttle response
  • Heat-treated forging for maximum strength and durability
  • Induction-hardened ring gear for extended lifespan
  • One-piece construction for reliability and uniform heat transfer
  • CNC machined and dynamically computer balanced for smooth high RPM operation
  • Serviceable and resurfacing capable without additional parts
  • Designed for race use with enhanced acceleration and engine response
