Exedy 2004-2011 Mazda 3 L4 Lightweight Flywheel

This is the Exedy ZF501A lightweight flywheel, designed for your 2004-2011 Mazda 3 L4. You get a solid, one-piece billet chromoly steel flywheel that weighs in at 13.0 lbs, significantly less than a stock unit. This reduction in weight and rotational inertia means your engine can rev up and down more quickly, making it feel more responsive, especially during spirited driving or track events.

Exedy builds these flywheels from solid billet chromoly steel, which offers good thermal capacity to handle the heat generated during clutch engagement. Unlike some aluminum flywheels where the ring gear is pressed on, the ring gear teeth are integrated directly into the steel flywheel. This design prevents potential separation issues caused by differing expansion rates. These flywheels are also SFI approved and have passed engineering tests up to 18,000 RPM, ensuring they are well-built for demanding use.

This flywheel is a popular choice for those looking to improve their clutch's performance and feel. It's designed to reduce weight and inertia for better engine response and includes features to help improve airflow and clutch cooling.
