ACT 2013-2018 Ford Focus ST/RS HD Race Sprung 6 Pad Clutch Kit

Part Details:

The FF5-HDG6 clutch kit features ACT’s most popular Heavy Duty pressure plate, engineered to deliver increased clamp load and long-term reliability in performance applications. ACT’s exclusive diaphragm design improves holding power while reducing deflection, helping maintain consistent engagement and extend clutch life under increased torque.

Each ACT Heavy Duty pressure plate undergoes a four-stage heat-treating process to ensure strength, durability, and consistent performance. Precision-stamped covers provide additional rigidity, helping maintain even clamp load across the friction surface during aggressive driving conditions.

Pressure Plate & Disc Design

This kit includes ACT’s 6-pad, spring-centered race disc, designed to withstand harsh driving conditions while properly damping torsional vibrations. The spring-centered hub helps absorb shock loads during engagement, reducing stress on the drivetrain compared to unsprung designs.

ACT spring retainers utilize wraparound spring windows and thicker retainer stampings to improve spring support and reduce stress concentrations. This design increases overall strength and reliability, particularly in high-load and high-heat environments.

Engagement Characteristics

With the 6-pad, spring-centered race disc, engagement is more aggressive compared to full-face disc designs, allowing for faster shifts and improved response. While engagement is firmer, this design is well suited for drivers who prioritize performance and durability over maximum comfort.

The 6-pad disc is recommended for larger clutch sizes where increased heat capacity is required, making it a strong option for vehicles subjected to frequent hard launches, spirited driving, or track-focused use.
