Product Description

The SPEC SF33A-4 is a lightweight billet aluminum flywheel for the 2013-2018 Ford Focus ST 2.0L EcoBoost, designed exclusively for use with SPEC's non-SAC mechanism clutch kits (the "-4" suffix series). This flywheel replaces the heavy factory dual-mass flywheel with a single-mass design that reduces rotating mass by approximately 50%, resulting in faster revving, less engine drag, and noticeably quicker throttle response. CNC machined from 6061-T6 billet aluminum to an industry-leading .001" tolerance, the flywheel guarantees a perfectly flat seating surface for the clutch and smooth rotational qualities for perfect balance and extended engine life.

The 1/4" thick friction plate is machined from 1050 high-carbon alloy for exceptional durability with any friction disc material and is secured by aerospace-grade fasteners chosen for their strength and corrosion resistance. The flywheel is fully rebuildable -- replacement friction plates and fasteners are available from SPEC, meaning you never need to buy a new flywheel at full price. SFI certified for safety. This flywheel will not work with the stock clutch or SPEC's stock-style SAC clutch kits -- for those applications, use SPEC SF33A-3 instead. Compatible non-SAC clutch kits include SF331-4 (Stage 1), SF332-4 (Stage 2), SF333H-4 (Stage 2+), SF333-4 (Stage 3), SF333F-4 (Stage 3+), SF334-4 (Stage 4), and SF335-4 (Stage 5). Made in the USA.
