Specifications: XT/Race Sprung 4 Pad Clutch Kit

  • Item Description: XT/Race Sprung 4 Pad
  • Product Weight (lbs.): 31.9
  • Torque Capacity (ft/lbs.): 681
  • Torque Capacity Over OE: 129%
  • Disc Material: Ceramic
  • Clutch Disc Diameter (Inches): 9.4
  • Clutch Disc Diameter (Millimeters): 240
  • Input Shaft Diameter (inches): 1
  • Pressure Plate Type: Xtreme
  • Flywheel Type: Prolite
  • Warranty: 12 Months (view details)

Description: The ZX4-XTG4 kit is tailored for the most demanding drivers, featuring an Xtreme pressure plate renowned for its exceptional performance. ACT Xtreme pressure plates utilize an exclusive diaphragm design to enhance clamp load, reduce deflection, and maximize clutch life. Through a four-stage heat-treating process, all diaphragms are meticulously treated for unparalleled performance. Precision cover stampings ensure rigidity and consistency, providing a reliable driving experience.

This kit includes ACT's 4-pad spring-centered race disc, designed with a spring-center construction to effectively dampen torsional vibrations and resist failure even under harsh conditions. ACT spring retainers are engineered with wraparound spring windows and thicker retainer stampings to provide spring support, reduce stress concentrations, and enhance strength and reliability. Although engagement may be harsher with the 4-pad spring-centered race disc, shifting is notably faster, making it ideal for high-horsepower street or race applications. Moreover, this disc is well-suited for smaller disc sizes in smaller engines.

Key Characteristics:

  • Feel: Moderate to heavy pedal effort, aggressive engagement, OE to mild gear rattle.
  • Life: Moderate friction life, extended by ACT's exclusive diaphragm design.
  • Quality: Carefully engineered, precisely assembled, accurately balanced, using select ceramic friction materials for high heat tolerance and maximum performance.

Recommended Use: Recommended for high horsepower street or race use, delivering exceptional performance and reliability.

ACT Difference: 100% clamp load tested and dynamically computer balanced for smooth high RPM reliability.

Vehicle Fitment: Compatible with various Mazda models, including the 2006-2013 Mazda 3 Mazdaspeed and the 2006-2007 Mazda 6 Mazdaspeed equipped with the 2.3 L4 GAS FI 2260cc | DOHC engine.

Frequently Asked Questions

Are ACT clutches balanced?

Yes! All ACT clutch assemblies are computer spin balanced to within .25 oz-in to guarantee help smooth operation across the entire RPM range. For comparison, stock production clutches are typically balanced to within .50 oz-in. Lower is definitely better!

Will an ACT clutch increase pedal effort?

ACT pressure plates are specifically designed to handle high torque applications. With ACT's durable design, expect an increase in pedal effort between 15-40% (Heavy Duty) and 50-80% (Xtreme), depending on the application. Clutches developed with less pedal effort often result in a lack of longevity, torque capacity and/or engagement quality.

Do ACT clutches require a break-in period?

For organic street discs, we recommend breaking in the clutch for 300-500 miles with mild engagement, such as stop-and-go city driving prior to racing or spirited driving. ACT race discs usually only require a few hard slips to lap in the surfaces prior to normal driving or racing. Do not overheat the clutch during the break-in period, as this can result in friction surfaces fusing together, hot spots, and friction surface glazing.

Are ACT clutches repairable or rebuildable?

In some situations, rebuilds or repairs may be possible (see warranty), after inspection of the clutch assembly. Please contact our technical department for further information. Because of special modifications, we do not recommend servicing by a general clutch rebuilder.

How much does an ACT clutch weigh?

The weight of the ACT clutch assembly will usually be the same as a stock OEM clutch assembly.
