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

T1SS-B01 Mod-Twin 225 HD Sprung Street Kit is designed for high-powered AWD street cars. It combines uncompromised pedal feel, durability, and engagement quality with very high torque capacity by pairing twice the organic friction surfaces with an ultra-durable spring-centered Mono-Drive hub in a completely modular design. Each diaphragm spring undergoes an exclusive four-stage heat-treatment process for a consistently light pedal feel. Steel-backed Friction Plates with high-quality organic friction materials deliver a stable friction coefficient, good heat capacity, and long clutch life. These Friction Plates transfer torque uniformly to the Mono-Drive sprung hub assembly, extending input shaft life and reducing 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.
