Product Description: HD/Perf Street Sprung Clutch Kit
The HD/Perf Street Sprung Clutch Kit, designated as Z65-HDSS, is engineered by ACT to provide optimal performance and durability for both street and race applications. With a weight of 15.9 pounds and a torque capacity of 330 ft/lbs, exceeding OE standards by 34%, this clutch kit delivers reliable power transfer and performance. Featuring an organic clutch disc material with a diameter of 9.4 inches (240mm) and an input shaft diameter of 1 inch, it offers a balance of performance and longevity.
At the core of this kit is ACT's most popular Heavy Duty pressure plate, designed to increase clamp load, reduce deflection, and maximize clutch life. Utilizing an exclusive diaphragm design and undergoing a meticulous four-stage heat-treating process, the Heavy Duty pressure plate ensures unparalleled performance and durability. Precision cover stampings guarantee rigidity and consistency for reliable operation in demanding conditions.
Paired with the Heavy Duty pressure plate is ACT's Performance Street disc, featuring premium organic materials with a high copper content for enhanced heat transfer and a steel-backed lining for greater burst strength and durability. With reduced marcel for faster shift action, this disc complements the Heavy Duty pressure plate, offering smooth positive engagement with OE to mild gear rattle.
Key Features:
- Feel: Light to moderate pedal effort, smooth positive engagement, with OE to mild gear rattle.
- Life: Longer friction life, extended by ACT's exclusive diaphragm design.
- Quality: Carefully engineered, precisely assembled, and accurately balanced, with premium organic friction materials for heat tolerance and reduced fade.
- Recommended Use: Suitable for both street and race use, catering to the needs of enthusiasts seeking reliable performance in various driving conditions.

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.
