Overview

The SPEC Billet SF33A is a lightweight aluminum flywheel designed for the 2013-2018 Ford Focus ST. It features billet construction for strength and durability, with a .001 machine tolerance for a flat seating surface. This flywheel is rebuildable, allowing for replacement of the friction surface. It is designed exclusively for use with SPEC specific clutch kits featuring a non-SAC (Self-Adjusting Clutch) mechanism pressure plate, and will not work with stock or SPEC stock-style clutch kits.
Show original supplier description
The SPEC Billet SF33A is a performance flywheel engineered from billet aluminum, offering reduced rotating mass for improved throttle response and higher RPM capabilities in your 2013-2018 Ford Focus ST. Manufactured to a precise .001 machine tolerance, it ensures optimal clutch engagement and engine balance for enhanced durability and extended engine life. It is crucial to note that this flywheel will NOT work with the factory clutch or any SPEC stock-style clutch kits. The non-SAC design offers advantages such as a lighter rotating assembly, higher RPM potential, and greater clamping load compared to the original Focus ST clutch system.
