XClutch 87-91 Mazda RX-7 10th Anniversary 1.3L Chromoly Flywheel

XClutch chromoly flywheels are designed and engineered for optimal performance and durability, utilizing high-quality materials for strength and weight reduction. They are developed for a wide range of vehicle applications, suitable for modified street cars, dedicated race cars, and off-road 4x4s. These flywheels are commonly used in both street and motorsport applications, offering low rotational inertia. The flywheel comes with an integral ring gear and timing sensor ring if applicable. RX-7 FC Prior to 1/89 requires counterweight FMZ004C-CW-K; RX-7 FC After 1/89 requires counterweight FMZ004C-CW2-K; RX-7 FD Requires counterweight FMZ004C-CW2-K; RX-8 Requires counterweight FMZ004C-CW3-K. Flywheels store rotational energy from the engine and transfer it to the transmission with a clutch. When replacing a clutch, it's recommended to replace or resurface the flywheel. Upgrading to an aftermarket lightweight flywheel can increase engine responsiveness.
