Product Description

The ACT T1SS-B01 Mod-Twin 225 HD Sprung Street kit is built for high-powered N54 and N55-equipped BMWs that need very high torque capacity without sacrificing everyday drivability. Doubling the organic friction surface area and pairing it with a sprung Mono-Drive hub delivers stable engagement and a consistent, light pedal feel while extending input shaft life and cutting driveline shock.

This fully modular kit includes a CNC-machined, dynamically balanced flywheel along with everything needed for installation, from the release bearing to the alignment tool. It's a strong fit for N54/N55 owners running elevated boost or power levels who want a street-friendly clutch that can still hold significant torque reliably over the long haul.
