Description:

The T2SS-F12 Mod-Twin 10.5 HD Sprung Street Kit is designed for high-powered street machines. It combines uncompromised pedal feel, durability, engagement quality, and very high torque capacity by utilizing twice the organic friction surfaces with an ultra-durable sprung Mono-Drive hub assembly in a completely modular design. Each diaphragm spring endures an exclusive four-stage heat-treating process to provide a consistent light pedal feel. Steel-backed friction plates with high-quality organic friction materials deliver stable friction coefficient, good heat capacity, and long clutch life. These friction plates uniformly transfer torque to the Mono-Drive sprung hub assembly, which extends input shaft life and reduces driveline shock from torsional vibration. This kit includes a CNC-machined and dynamically balanced flywheel, pressure plate cover, diaphragm spring, face, puck-style ceramic friction plates, sprung Mono-Drive hub assembly, floater, alignment tool, and pilot bearing (where applicable). Mod-Twin clutches are fully rebuildable, and replacement discs may be ordered separately.

Description:

  • Feel: Soft, progressive engagement, light pedal effort, smooth shifting with OE to mild transmission gear noise
  • Life: Forged Aluminum Cover, Mono-drive hub, exclusive diaphragm, and premium friction materials ensure this long-life twin performs and survives under the most demanding conditions
  • Quality: Delivers maximum performance and high heat tolerance by combining robust design, strategic features, choice materials, and close tolerances
  • Recommended Use: Street or Street/Strip

ACT Difference: Applying tactical engineering to the Mod-Twin, ACT presents unique solutions to common tradeoffs found on twin-disc clutches, resulting in an ultra-durable, customer serviceable, long-lasting clutch with very high torque capacity. All are 100% clamp load tested, balanced, and SFI certified.

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.
