Action Clutch Chromoly lightweight flywheel for Mitsubishi 3000GT VR-4 (1991–1999) is heat-treated for durability and tested to 18,000 RPM. The chromoly construction reduces rotational mass for faster engine response and improved throttle feel, while offering high thermal capacity and resurfacing potential for extended service life. Note that reduced mass may introduce increased NVH (noise, vibration and harshness).
