Description

The ACT Prolite Flywheel Kit (Part Number 600140-03) delivers exceptional performance and precision for Mazda RX-7 and RX-8 rotary-powered vehicles. This complete kit includes ACT’s lightweight forged Prolite Flywheel and a precisely matched ACT counterweight, ensuring proper external balance for manual transmission applications. Engineered for both street and competition use, the Prolite Flywheel provides lightning-fast throttle response, improved acceleration, and smooth engagement across all RPM ranges.

Crafted from heat-treated forged steel, the flywheel offers superior strength, toughness, and heat tolerance under demanding racing conditions. The induction-hardened ring gear extends service life, while the one-piece design minimizes failure points and promotes uniform heat transfer from the clutch disc. CNC machining and dynamic balancing ensure vibration-free performance, even during aggressive driving or high-RPM operation.

Fully serviceable and resurfaceable without the need for additional components, this kit provides long-term reliability and cost efficiency. Ideal for road racing, rally, and performance street use, the ACT Prolite Flywheel Kit enhances driveline response, power delivery, and overall vehicle performance — making it a trusted upgrade for Mazda rotary enthusiasts.

Features:

  • Includes a high-strength heat-treated forged flywheel with induction-hardened ring gear for maximum durability
  • Lightweight Prolite design reduces rotational inertia for improved throttle response and acceleration
  • Dynamically computer balanced for smooth high RPM operation
  • Designed with proper material distribution for maximum strength, heat tolerance, and rigidity
  • Complete with ACT counterweight for correct external balance in manual transmission applications
  • Serviceable design allows resurfacing without additional parts
  • Ideal for street, rally, and road racing applications on Mazda RX-7 and RX-8 models
