2013-2018 Focus ST EcoBoost SPEC Stage 3 Clutch Kit (Non-SAC) SF333-4

Uprated Focus ST Non-Self Adjusting Clutch Kit

While a self-adjusting clutch (SAC) is all well and good for ride comfort and general ergonomics, a non-SAC clutch design gives you much better bang for your buck when it comes to power potential on your quick hot hatch. The Non-SAC SPEC Stage 3 clutch kit for the 2013-2018 Focus STs can hold up to 580lb-ft of torque, giving it much higher power capacity than your factory clutch in a package that will handle and feel near-stock. SPEC's non-SAC Stage 3 Focus ST clutch kit is not compatible with your Focus ST's stock dual-mass flywheel and will require SPEC's Billet Aluminum Flywheel for Non-SAC Clutches for proper fitment and operation.

Kevlar-Organic Friction Disk with Steel Backing

The SPEC Stage 3 Clutch Kit provides your Focus with faster and firmer engagement than stock while keeping your street ride clean and collected. Each of SPEC's Stage 3 clutches feature a six-puck friction disk lined with a semi-metallic carbon material that provides excellent torque capacity without a huge increase in overall mass to maintain clean shifting and fast revving for driving on the street. The high-quality components can handle high clamps loads and extremely high temperatures, making it suitable for aggressive driving. The kit comes standard with a double-sprung hub disc made with heat-treated components for extreme levels of durability. The non-SAC design reduces the clutch's weight and mass while improving clamping pressure for better power-holding in a similar design.

Flywheel Fitment: this SPEC clutch kit is not compatible with your stock dual-mass flywheel and requires SPEC's Billet Aluminum Flywheel for Non-SAC Clutches.
