They offer near-stock drivability, tremendous life expectancy, a no shimming/setup bolt-in installation, and maintenance-free operation. With their all-billet construction, these assemblies are smooth and quiet. Super Twins are constructed with aircraft-grade aluminum and high-carbon billet steel milled to industry-leading .001 in. tolerances for perfect balance and actuation. Friction is provided by dampened, full-faced, carbon-graphite discs. Additional features of SPEC Super Twin multi-disc clutch and flywheel kits: * Organic, fiber, and full-metallic versions are also available * Flywheel and track-spec hardware are included in each kit * Rebuildable by SPEC or the end-user * Replacement components are always available * Ideal for all types of use, including: street, drag racing, drifting, road racing, time-attack, pulling, and rally

South Bend Clutch Stage 3 Endurance clutch kits are recommended for single mass flywheel (SMF) when original design is DMF (dual mass) to achieve optimal performance. These kits use the same race-engineered SFI-approved pressure plates as Stage 3 Daily Driver packages. The disc is designed for the special needs of a vehicle with circuit racing in mind. Kevlar® friction material is used for its unique friction compounds applied with high-energy levels. This translates to a perfect transition from one gear to the next. Discs are assembled with only performance components and equipped with torsion springs functioning as a damper between engine and gearbox. These Stage 3 Endurance clutch kits are recommended for applications such as rally, endurance race, club sport, autocross, performance street and daily driving. Order the kit you need.

ACT Mod-Twin 225 heavy-duty twin-disc street clutch kits are designed to tackle aggressive launches and rapid shifting of high powered AWD's—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 4-stage heat treating process to provide a more consistent light pedal feel. The puck-style friction plates, with high-quality organic materials, deliver high friction coefficient, superior 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. Clutch kits are available in different styles and other options for fitment on countless vehicles from the early 2000s and up. Features and benefits: * Recommended for drag, road, or rally racing use * Predictable aggressive engagement, light pedal effort, smooth shifting, possible start-off judder 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 * 100 percent clamp load tested, balanced, and SFI certified Kit contents: * Forged aluminum pressure-plate cover * CNC-machined and dynamically balanced flywheel * Diaphragm spring and face * Puck-style organic friction plates * Available with sprung or unsprung mono-drive hub assembly * Floater * Patented mono-Loc collar * Release bearing * Alignment tool and pilot bearing (if needed) Note: Mod-Twin clutches are fully rebuildable and most components can also be ordered separately, if you do not need to purchase complete kit.
