Description

Mod-Twin Kit

T2S-S07 Mod-Twin 225 XT 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.

Clutch Kits, Mod-Twin 225 Xtreme Twin-Disc, Performance, Organic, 1.000 in. - 24-spline, 8.800 in. Disc, SFI Certified 1.2, Subaru, 2.5L, Kit

ACT Mod-Twin 225 Extreme twin-disc street clutch kits will provide 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 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 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.

• Recommended for drag, road, or rally racing use
