Advanced Clutch Mod-Twin 225 XT Rigid Race T2R-MZ01 Mod-Twin 225 XT Rigid Race Kit tackles 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 four-stage heat treating process providing a consistent light pedal feel. Puck-style Friction Plates with high quality ceramic friction materials deliver high friction coefficient, superior 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. Notes: Flywheel requires counterweight (not included). Features: Predictable aggressive engagement, light pedal effort, quick shifting, possible start-off judder 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 Drag, Road or Rally Racing 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 Specifications: Clutch Master Cylinder Included: No Grease Included: Yes Grade Type: Performance Flywheel Included: Yes Pressure Plate Type: Xtreme Release Bearing Included: Yes Clutch Disc Diameter: 8.8 in Clutch Disc Diameter: 225 mm Disc Material: Organic Input Spline Quantity: 23 Input Shaft Diameter: 1 in Alignment Tool Included: Yes Disc Type Sprung Solid: Solid Clutch Slave Cylinder Included: No Flywheel Bolts Included: Yes Product Weight (lbs.): 28.8 SFI: 1.2 Torque Capacity (ft/lbs.): 895 Torque Capacity Over OE: 2.14 References Installation Instructions Applications 1993 Mazda RX-7 Base 1993 Mazda RX-7 R1 1993 Mazda RX-7 Touring 1994 Mazda RX-7 Base 1994 Mazda RX-7 R2 1994 Mazda RX-7 Touring 1995 Mazda RX-7 Base 1995 Mazda RX-7 R2 1995 Mazda RX-7 Touring
