Sku: HC7-HDG4
ACT

Specifications:

  • Item Description: HD/Race Sprung 4 Pad
  • Product Weight: 10.5 lbs.
  • Torque Capacity: 300 ft/lbs.
  • Torque Capacity Over OE: 96%
  • Disc Material: Ceramic
  • Clutch Disc Diameter (Inches): 8.3 inches
  • Clutch Disc Diameter (Millimeters): 212 mm
  • Input Shaft Diameter (inches): 0.875 inches
  • Pressure Plate Type: Heavy Duty
  • Warranty: 12 Months

Description:

The HC7-HDG4 kit features ACT's most popular Heavy Duty pressure plate. ACT Heavy Duty pressure plates utilize an exclusive diaphragm design to increase clamp load, reduce deflection, and maximize clutch life. Each diaphragm undergoes a four-stage heat-treating process for unparalleled performance. Precision cover stampings ensure rigidity and consistency in the pressure plate. The kit includes ACT's 4-pad spring-centered race disc, which features a spring-center construction to properly damp torsional vibrations for quieter operation and resist failure even under harsh conditions. ACT spring retainers utilize wraparound spring windows and thicker retainer stampings to provide spring support, reduce stress concentrations, and increase strength and reliability. With the 4-pad spring-centered race disc, engagement is harsher, but shifting is faster. ACT's 4-pad spring-centered race disc is well-suited for smaller disc sizes in smaller engines.

Description:

  • Feel: Light to moderate pedal effort, aggressive engagement, OE to mild gear rattle

Vehicle Fitment:

  • Application: 1988 Honda Civic RT 4WD: 1.6 L4 GAS FI 1588cc | SOHC | Naturally Aspirated

PROP 65 WARNING: This product can expose you to chemicals including carbon black, glass wool fibers, and silica (in clutch discs), chromium, and nickel, which are known to the State of California to cause cancer or birth defects or other reproductive harm.

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.
