ACT J014 Heavy Duty Clutch Pressure Plate - 11-Inch Diaphragm SFI 1.1

The ACT J014 Heavy Duty Clutch Pressure Plate is a performance-grade diaphragm-style pressure plate engineered for demanding street and race applications. Featuring an 11-inch (280mm) friction surface diameter, this pressure plate delivers a significant increase in clamping force while maintaining a manageable, stock-to-moderate pedal feel.

ACT's exclusive diaphragm design increases clamp load by 20 to 50 percent over the stock unit, reducing deflection and maximizing clutch disc life. Every diaphragm undergoes a rigorous four-stage heat-treating process to ensure consistent, long-lasting performance under high-demand conditions.

Key Features:

• Exclusive Diaphragm Design — Increases clamp load, reduces deflection, and extends clutch life
• Four-Stage Heat-Treated Diaphragm — Ensures durability and consistent performance under heavy use
• Precision Cover Stampings — CNC-machined castings provide rigidity, consistency, and superior heat absorption
• Induction-Hardened Diaphragm Fingers — Reduces wear and promotes smooth, reliable engagement
• Stronger Drive Straps and High-Grade Rivets — Reinforced construction prevents breakage under high power and high RPM loads
• 100% Clamp Load Tested — Every unit is dynamically computer spin-balanced for smooth, high-RPM reliability
• SFI 1.1 Certified — Approved for use in sanctioned racing organizations requiring SFI certification
• Mounting Hardware Included — Comes with the necessary hardware for installation
• Street and Race Recommended — Compatible with street or race clutch discs

The ACT J014 is sold individually and must be used with an ACT flywheel and clutch disc, which are sold separately. With light-to-moderate pedal effort and positive engagement, this pressure plate is the most popular choice for drivers seeking a reliable performance upgrade without sacrificing daily drivability.
