2013-2018 Focus ST EcoBoost SPEC Billet Aluminum Flywheel (Non-SAC Only) SF33A-4

Drop-In Replacement Flywheel for Focus ST Non-SAC Clutch Kits

To get the most bang-for-your-buck when it comes to your Focus ST's drivetrain, you'll need to switch over from a Self-Adjusting Clutch (SAC) to a non-SAC design. In order to do that, you'll need the correct flywheel, and this Billet Aluminum Non-SAC Flywheel from our friends over at SPEC is your winning ticket. This lightweight flywheel is a bolt-on replacement for your 2013-2018 Focus ST's stock dual-mass flywheel and allows you to use extremely powerful Non-SAC clutches for your extremely high performance build. This SPEC flywheel is not compatible with your factory clutch, but allows you to choose one of SPEC's purpose-built non-SAC clutches which can hold more power than a traditional OEM replacement clutch kit. So, if you're going for massive power, this kit is your winning ticket.

Fits Powerful Non-SAC Clutches for Improved Power Capabilities

SPEC's non-SAC Billet Aluminum Flywheel is much lighter than your Focus ST's dual mass flywheel, which allows for faster revving. While much lighter and packing in less mass, SPEC's flywheel is also CNC machined out of extremely strong billet aluminum which allows it to handle extreme levels of torque beyond the 600lb-ft range. The flywheel can be rebuilt and resurfaced an infinite amount of times and has a low MOI design to maximize your Focus ST's performance. Each of these flywheels drops right into place of your ST's stock flywheel and comes with instructions and hardware.

Not compatible with factory clutch: this flywheel will only fit and function with aftermarket non-SAC clutches. If you need a flywheel for your stock clutch, check out SPEC's flywheel for OEM clutches.
