The Clutch Masters FX400 6-puck dampened disc clutch kit for 2014–2018 Mazda3 2.5L 6-speed is a sprung-damper design built to work with a single-mass flywheel made to OEM specifications. It provides a controlled engagement profile with torsional damping to reduce driveline shock while retaining direct-fit installation where a single-mass flywheel is present; it is not compatible with dual-mass flywheels.
