This kit contains a custom made single mass flywheel and a reinforced stage 1 clutch. The damping function of the OEM dual mass flywheel is moved to the clutch center section. This has the advantage the flywheel is no longer a limiting factor in the amount of torque it can handle. This combination is recommended for tuned JTD setups (up to 390 Nm torque) with slightly reduced comfort compared to OEM parts. Suitable for Alfa 147,156,166,GT 1.9 JTD & 2.4 JTD engines (105,110,115,120,136,140,150, 170 hp versions)
