ACT 07-18 BMW 3.0L Turbo (N54/N55) Mod-Twin 225 HD Rigid Street

T1S-B05 Mod-Twin 225 HD Rigid Street Kit combines easy pedal effort, smooth yet positive engagement, and quick shifting for high-powered AWD vehicles by pairing twice the organic friction surfaces with a no-nonsense rigid Mono-Drive hub in a fully modular design. Each diaphragm spring undergoes an exclusive four-stage heat-treating process. Steel-backed friction plates with high-quality organic friction materials provide a stable coefficient of friction, good heat capacity, and long clutch life. These friction plates transfer torque uniformly to a heat-treated chrome-moly Mono-Drive hub for strength and durability, extending input shaft life with a single continuous spline. The lightweight, rigid design enables 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.
