Description:

  • The BM13-HDSS kit combines ACT's popular Heavy Duty pressure plate with their preferred street disc, offering a blend of performance and durability. The Heavy Duty pressure plate utilizes an exclusive diaphragm design to enhance clamp load, minimize deflection, and extend clutch life. It undergoes a rigorous four-stage heat-treating process for superior performance and durability. Precision cover stampings ensure rigidity and consistency. The Performance Street disc is crafted with premium organic materials containing high copper content for efficient heat transfer, while its steel-backed lining enhances burst strength and longevity. With reduced marcel, these discs facilitate quicker shift action, complementing the pressure plates for enhanced reliability and strength.

Description (Characteristics):

  • Feel: Light to moderate pedal effort, smooth positive engagement, OE to mild gear rattle
  • Life: Longer friction life, extended by ACT's exclusive diaphragm design
  • Quality: Carefully engineered, precisely assembled, accurately balanced, with premium organic friction materials for heat tolerance and reduced fade
  • Recommended Use: Ideal for street and occasional 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.
