Each kit (MPN: ACR-1405) undergoes rigorous quality control and is signed off by an experienced engineer to ensure reliable performance on the track.

The Action Clutch Retrofit Chromoly Lightweight Flywheel (MPN AC132FW-RT) is engineered for high-performance street and track applications. By reducing rotational mass, this flywheel significantly improves throttle response and engine acceleration. Each unit is manufactured from forged 4140 chromoly steel and undergoes a specialized heat-treatment process to ensure maximum durability and high thermal capacity.

Designed to withstand the rigors of racing, these flywheels are tested up to 18,000 RPM. The one-piece construction offers superior reliability over multi-piece designs, and the surface is fully resurfaceable to provide a long service life. Note that reducing rotational mass may introduce slight increases in noise, vibration, and harshness (NVH) compared to the factory dual-mass unit.

• Material: Forged 4140 Chromoly Steel
• RPM Rating: Tested up to 18,000 RPM
• Configuration: Retrofit style for 1.5L Turbo applications
• Serviceability: Fully resurfaceable design
• Manufacturer Part Number: AC132FW-RT
