ACT T1S-M01 Mod-Twin 225 HD Sprung Street Clutch Kit for Mitsubishi Lancer Evolution 8/9 5-Speed

T1S-M01 Mod-Twin 225 HD Sprung Street Kit is designed for high powered AWD street cars. It unites uncompromised pedal feel, durability, engagement quality with very high torque capacity by combining twice the organic friction surfaces with an ultra-durable spring center Mono-Drive hub in a completely modular design. Each diaphragm spring endures an exclusive four-stage heat treating process providing 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, 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 Sprung Street Soft progressive engagement, light pedal effort, smooth shifting with OE to mild 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-M01 Mod-Twin 225 HD Sprung Street Kit is engineered for high-powered AWD street cars that demand responsive engagement, dependable durability, and substantial torque capacity. Designed for Mitsubishi Lancer Evolution 8 and 9 applications with a 5-speed transmission, this twin-disc clutch system combines dual organic friction surfaces with a sprung Mono-Drive hub to provide strong power handling while helping reduce driveline shock and torsional vibration.

The kit uses an exclusively heat-treated diaphragm spring for consistent clamp load and light pedal effort. Steel-backed friction plates with premium organic materials provide stable friction characteristics, smooth progressive engagement, good heat tolerance, and long service life. A forged aluminum cover, hardened wear points, CNC-machined flywheel, and dynamically balanced components support reliable operation under demanding street or street-and-strip conditions. The design also maintains smooth shifting with OE-like to mild transmission gear noise.

ACT builds the Mod-Twin as a fully rebuildable clutch system, allowing most components to be serviced or ordered separately when needed. Every unit is clamp-load tested, dynamically balanced, and SFI certified. The patented Monoloc Collar, sprung Mono-Drive hub assembly, and included pilot bearing help support dependable installation and long-term drivetrain performance. ACT backs the T1S-M01 with a one-year warranty.
