Action Clutch Flywheels: Precision-Engineered for Performance Driving

When it comes to extracting every last bit of power from your drivetrain, the flywheel is often an overlooked but critical component. Action Clutch — a Los Angeles-based, family-owned performance brand with roots stretching back to 1962 — brings the same obsessive engineering philosophy to their flywheel lineup that has made them a benchmark name in the clutch world. Whether you are building a spirited street car or a dedicated track weapon, Action Clutch flywheels are purpose-built to match.

Chromoly Construction: The Foundation of Action Clutch Flywheels

Action Clutch Racing (ACR) flywheels are CNC machined from a single piece of high-grade forged chrome-moly — a material that is typically 3x stiffer than aluminum, can be resurfaced, and is resistant to fatigue and wear. This matters enormously in high-stress performance applications, where inferior flywheel materials can distort, crack, or fail under repeated heat cycles.

Action Clutch Chromoly Lightweight Flywheels are the perfect upgrade for light to high-tuned street and race vehicles. They stand up to extreme use and feature increased durability through a heat treatment process. These flywheels deliver three major benefits: low weight, low inertia, and high thermal capacity — made from one-piece billet chromoly steel or chromoly steel forgings specifically for vehicles that see drag racing, drifting, autocross, street use, and rally.

Lightweight Steel Options: The Smart Middle Ground

Not every build calls for the lightest possible flywheel. Action Clutch lightweight steel flywheels are designed and engineered in the USA and offer a weight reduction of up to 60%, making them ideal for improved throttle response, quicker shifting, and reduced clutch wear. Action Clutch ensures not to go too light while still delivering a major weight reduction — a critical balance that preserves drivability and avoids the excessive chatter that can plague ultra-lightweight aluminum alternatives.

At around 16.5 lbs in some applications, their chromoly single-mass designs strike a great balance between a heavy stock flywheel and a lightweight aluminum flywheel , making them an ideal choice for drivers who want real-world usability alongside measurable performance gains.

Wide Application Coverage

Action Clutch offers both aluminum and chromoly flywheel options to reduce rotational inertia and dramatically improve throttle response, with extensive application support for high-horsepower platforms including the Nissan SR20DET, Honda B/K-Series, Toyota 2JZ-GTE, and more. Specific part numbers exist for popular platforms like the Honda Civic Type R (2017–2021), the Accord 2.0L, and the Accord V6/Acura TL Type-S.

Engineered to Pair with the Full Action Clutch System

Action Clutch flywheels are designed to work seamlessly with the brand's full range of clutch kits — from Stage 1 street setups all the way up to multi-disc race configurations. Many flywheel options fit the stock clutch for an affordable upgrade, while also being compatible with all single-disc Action Clutch offerings. This makes them a natural first upgrade when moving to a performance clutch kit.

All Action Clutch kits and components meet SFI standards, certifying their safety for racing purposes according to The SFI Foundation, Inc. When you pair an Action Clutch flywheel with one of their staged clutch kits, you get a complete drivetrain solution backed by over six decades of hands-on performance engineering from a brand that racers and street enthusiasts alike trust to get power to the wheels.
