ACT 99-02 Nissan Skyline GT-R (R34) Mod-Twin 225 XT Sprung Street

T2SS-N04 Mod-Twin 225 XT 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 XT 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

The ACT T2SS-N04 Mod-Twin 225 XT Sprung Street Kit is engineered for high-powered AWD street cars, including the 1999-2002 Nissan Skyline GT-R R34. This twin-disc clutch combines excellent pedal feel, durable construction, smooth engagement, and high torque capacity in a completely modular design. By doubling the organic friction surfaces and using an ultra-durable sprung Mono-Drive hub, the kit delivers dependable performance for demanding street and street-strip applications.
Each diaphragm spring undergoes an exclusive four-stage heat-treating process to provide consistent clamping force and light pedal effort. Steel-backed friction plates with premium organic friction material offer a stable friction coefficient, strong heat capacity, and extended clutch life. The plates transfer torque evenly through the sprung Mono-Drive hub assembly, helping reduce driveline shock caused by torsional vibration while supporting long input-shaft life. The result is soft, progressive engagement, smooth shifting, and original-equipment to mild transmission gear noise.
The ACT T2SS-N04 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 when required. Its forged aluminum cover, hardened wear points, premium friction materials, and close-tolerance design support reliable operation under high heat and heavy use. Mod-Twin clutches are fully rebuildable, with most components available separately for convenient service. Every kit is clamp-load tested, balanced, and SFI certified, and is backed by ACT's one-year warranty.
