Action Clutch AC121FW Chromoly Lightweight Flywheel for Mazda RX-7 Rotary Turbo

The Action Clutch AC121FW is a high-performance chromoly steel lightweight flywheel engineered specifically for Mazda RX-7 rotary engines. This precision-machined flywheel reduces rotational mass compared to the heavy factory unit, delivering quicker throttle response, faster rev transitions, and improved acceleration characteristics crucial for turbocharged rotary applications.

Key Features:

• Chromoly steel construction for superior strength-to-weight ratio and heat resistance
• Lightweight design reduces rotational inertia for enhanced engine responsiveness
• Includes counterweight for proper rotary engine balance
• Precision-machined friction surface for optimal clutch engagement
• Compatible with Mazda RX-7 FC (1986-1988) and FD (1992-1995) models with 1.3L 13B turbocharged rotary engines
• Direct replacement for factory flywheel

This flywheel is ideal for street performance, road racing, and drift applications where quick power delivery and responsive engine characteristics are essential. The included counterweight ensures proper engine balance critical to rotary engine longevity and smooth operation. Must be used with a compatible performance clutch disc and pressure plate assembly.
