What is the main benefit of a steel flywheel over a stock flywheel?

Steel flywheels are generally more durable and better at dissipating heat compared to some stock flywheels, especially in performance applications. This SPEC steel flywheel is well-built to handle the stresses of higher RPMs and torque.

Does this flywheel come with the necessary hardware for installation?

This SPEC steel flywheel is sold individually. It is recommended to inspect and potentially replace clutch bolts and other associated hardware during installation, as these are often not included with the flywheel itself.

What other clutch components should I consider replacing when installing a new flywheel?

When replacing your flywheel, it's a good time to inspect and consider replacing your clutch disc, pressure plate, and release bearing. This ensures all components are working together optimally and can save on future labor costs.
