ACT T1S-M03 Mod-Twin 225 HD Rigid Street Clutch Kit for Mitsubishi Lancer Evolution 8/9 5-Speed

T1S-M03 Mod-Twin 225 HD Rigid Street Kit blends easy pedal feel, smooth but positive engagement with quick shifting for high powered AWD’s by combining twice the organic friction surfaces with a no-nonsense rigid Mono-Drive hub in a completely modular design. Each diaphragm spring endures an exclusive four-stage heat treating process. 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 a Mono-Drive chrome-moly 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, patented Monoloc Collar, release bearing, alignment tool and pilot bearing (if needed). Mod-Twin clutches are fully rebuildable and most components can be ordered separately. Mod-Twin 225 HD Rigid Street Soft progressive engagement, light pedal effort, smooth shifting, with mild to moderate transmission gear noise; Forged Aluminum Cover, Mono-drive hub, exclusive diaphragm, premium friction materials, and hardened wear points ensure this long-life twin performs and survives under the most demanding conditions; Delivers maximum performance and high heat tolerance by combining robust design, strategic features, choice materials, and close tolerances; Street or Street/Strip; 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

• "Excellence in Performance", backed by the best one-year warranty in the industry!

The ACT T1S-M03 Mod-Twin 225 HD Rigid Street Kit is engineered for high-powered, all-wheel-drive Mitsubishi Lancer applications requiring strong torque capacity, smooth engagement, and quick shifting. Designed for Evolution 8 and 9 five-speed transmissions, this modular twin-disc clutch combines twice the organic friction surface area with a rigid Mono-Drive hub for dependable power transfer and long service life. Its progressive pedal feel and positive engagement make it suitable for demanding street and street/strip use.

Each diaphragm spring undergoes ACT's exclusive four-stage heat-treating process, while steel-backed friction plates use premium organic friction material to provide a stable coefficient of friction, strong heat capacity, and consistent performance. The chrome-moly Mono-Drive hub is heat treated for strength and durability, helping reduce input shaft wear through its continuous spline design. A forged aluminum cover, hardened wear points, close manufacturing tolerances, and a lightweight rigid construction support fast shifts with mild to moderate transmission gear noise.

The ACT T1S-M03 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, patented Monoloc Collar, release bearing, alignment tool, and pilot bearing when required. The clutch is fully rebuildable, and many components are available separately for long-term serviceability. Every kit is clamp-load tested, balanced, and SFI certified, and is backed by ACT's one-year warranty.
