ACT 2013-2018 Ford Focus ST/RS HD Performance Street Sprung Clutch Kit

Part Details:

The FF5-HDSS clutch kit features ACT’s most popular Heavy Duty pressure plate paired with their Performance Street disc, creating a balanced clutch solution designed for increased torque capacity while maintaining smooth street drivability. This combination is ideal for performance-oriented street builds that require improved holding power without sacrificing comfort.

ACT Heavy Duty pressure plates utilize an exclusive diaphragm design to increase clamp load while reducing deflection. This design helps maintain consistent engagement and maximizes clutch life under higher torque conditions. Each diaphragm undergoes a four-stage heat-treating process to ensure durability and consistent performance.

Pressure Plate & Disc Design

Precision-stamped pressure plate covers provide added rigidity and consistency, helping distribute clamp load evenly across the friction surface. This contributes to reliable engagement and reduced wear during spirited driving.

The included ACT Performance Street disc features premium organic friction materials with high copper content to improve heat transfer. A steel-backed lining increases burst strength and overall durability, making the disc well suited for daily-driven performance applications.

Street-Focused Engagement Characteristics

ACT Performance Street discs are designed with reduced marcel to provide quicker shift action while retaining smooth engagement. This design complements the Heavy Duty pressure plate by delivering responsive shifts without the harsh engagement typically associated with more aggressive race-style discs.

The result is a clutch that offers increased strength and reliability over factory components while remaining comfortable and predictable for everyday driving.
