Mod-Twin Kit

T1S-M07 Mod-Twin 225 HD Rigid Street Kit blends easy pedal feel, smooth but positive engagement with quick shifting for high powered AWD’s by combining twice the organic friction surfaces with a no-nonsense rigid Mono-Drive hub in a completely modular design. Each diaphragm spring endures an exclusive four-stage heat treating process. 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 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.

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.
