ACT Streetlite Xact Flywheels

ACT Streetlite Xact flywheels are designed to provide significantly improved engine response and acceleration at an affordable price. Order the model designed for your vehicle application. Features: * Lighter and stronger than OE flywheels * Better drivability and durability * Recommended for street use and drag racing * Designed using the latest CAD and Finite Element Analysis software * CNC-machined and dynamically computer-balanced for smooth operation at extremely high rpm * Entire forgings are heat-treated for strength and toughness * Tight tolerances for fit, concentricity, and parallelism * Adequate material behind the friction surface for excellent heat capacity * One-piece construction for reduced failure and uniform, efficient heat transfer—no more warped inserts * Integral ring gears are induction-hardened for longer gear life and weight reduction where it matters most—eliminates gear breakage or separation * Ring gears are cut with lead-in chamfers for better starter engagement and to prevent rounding-off gear teeth * SFI-certified

ACT Race Clutch Discs

ACT race clutch discs are available in three distinct styles--choose the options that best suit your application. Spring-centered discs are the most popular and feature reduced driveline shock and spline wear with quieter operation. Rigid-hub versions offer improved durability but increase gear noise and spline wear. For either of those hub designs, you can choose six pads for better heat management and engagement, or four pads for the quickest shifting. Sintered iron discs offer the highest torque capacity and ultra-high heat capacity. They're designed for cars using clutch-less shifting or drag racing transmissions. Additional product details: * Premium ceramic friction materials provide high-heat tolerance, high coefficient of friction, and low wear rates * Carefully broached splines provide exact fit onto the transmission input shaft for long spline life and better clutch release * Heavy-duty torsional dampening springs are provided in the best sizes and spring rates to help reduce noise * Drive plates are made of high-carbon steel; heat-treated and black zinc coated to resist bending, cracking, fatigue, and rusting * Certified to SFI specifications

ACT Mod-Twin 225 Extreme Twin-Disc Race Clutch Kits

ACT Mod-Twin 225 Extreme twin-disc race clutch kits will provide aggressive launches and rapid shifting of high powered AWD's--by combining twice the ceramic 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 consistent light pedal feel. The puck-style friction plates with high-quality ceramic 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 of these clutch kits allows for quicker shifts and lasting trouble-free service. Different styles and other options are available for vehicle fitment from 2003 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 ceramic friction plates * Available with sprung or rigid 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.

ACT Mod-Twin 225 Heavy-Duty Twin-Disc Street Clutch Kits

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.
