Fidanza LSX/LSA/LS9 8-Bolt Aluminum Conversion Flywheel

This Fidanza aluminum flywheel is designed for LSX, LSA, and LS9 engines that use an 8-bolt crankshaft. What you get is a well-built flywheel that's lighter than stock, which helps your engine rev more freely and can free up some extra horsepower. It comes with military spec fasteners, meaning they're built to a high standard for reliability and strength, which is important for something as critical as your flywheel.

The aluminum construction makes this flywheel noticeably lighter than a cast iron or steel unit. This reduced rotational mass means your engine doesn't have to work as hard to spin it up, leading to quicker throttle response and a more eager feel when you accelerate. Fidanza also includes a bolt-on replaceable friction plate. This is a smart feature because if the friction surface wears out over time, you can simply replace the plate instead of the entire flywheel, saving you money and hassle down the road. This makes it a solid, long-term option for your build.

When installing this, remember that it's a critical drivetrain component. Always follow the manufacturer's recommended installation procedures and torque specifications. Ensure your clutch disc and pressure plate are compatible with this flywheel's dimensions and bolt pattern for a smooth and reliable engagement.
