T1S-N06 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.
