Description
T1S-G13 Mod-Twin 10.5 HD Rigid Street Kit blends easy pedal feel, smooth but positive engagement with quick shifting for high-powered street machines by combining twice the organic friction surfaces with a no-nonsense solid Mono-Drive hub in a completely modular design. Each diaphragm spring endures an exclusive four-stage heat treating process to provide a light and consistent pedal feel. Steel-backed Friction Plates with high quality performance organic friction materials deliver stable friction coefficient, improved heat capacity and long clutch life. These Friction Plates uniformly transfer torque to a Mono-Drive Chromoly hub, which is heat treated for strength and durability, extending input shaft life with one continuous spline. The lightweight, rigid design allows for quicker shifts and trouble-free service. This kit includes a CNC-machined and dynamically balanced flywheel, pressure plate cover, diaphragm spring, face, puck-style ceramic friction plates, rigid Mono-Drive hub, floater, alignment tool and pilot bearing (where applicable). Mod-Twin clutches are fully rebuildable, and replacement discs may be ordered separately.
| Feel | Soft, progressive engagement, lightest pedal effort, smooth shifting with mild to moderate 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.
