Description:

The BM14-HDSD kit from ACT features their most popular Heavy Duty pressure plate. Utilizing an exclusive diaphragm design, ACT Heavy Duty pressure plates increase clamp load, reduce deflection, and maximize clutch life. These diaphragms undergo a meticulous four-stage heat-treating process for unparalleled performance. Precision cover stampings ensure rigidity and consistency.

The performance street rigid-hub discs boast premium organic materials with high copper content for superior heat transfer and steel-backed lining for increased burst strength and durability. Heat-treated chrome-moly hubs enhance strength and durability, while carefully selected rivet design and materials maximize strength. These discs, with their rigid design, facilitate faster shifts, making them ideal for street use with race-proven performance.

Key Features:

  • Feel: Light to moderate pedal effort, smooth positive engagement, increased gear rattle.
  • Life: Longer friction life extended by ACT's exclusive diaphragm design; however, the rigid design may increase spline wear.
  • Quality: Carefully engineered, precisely assembled, and accurately balanced, featuring premium organic friction materials for heat tolerance and reduced fade.
  • Recommended Use: Recommended for both street and race use.
  • ACT Difference: 100% clamp load tested and dynamically computer balanced for smooth high RPM reliability.

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.
