T1RS-N06 Mod-Twin 225 HD Sprung Race Kit performs aggressive launches and smoother shifting in high powered AWD’s by combining twice the ceramic friction surfaces with an ultra-durable Mono-Drive sprung hub assembly 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 sprung hub assembly which extends input shaft life and reduces driveline shock from torsional vibration. This kit includes a CNC-machined and dynamically balanced flywheel pressure plate cover diaphragm spring face puck-style ceramic friction plates sprung Mono-Drive hub assembly 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.
