The Mugen V2 4 Shoe Clutch Set was designed to be easy to work on and more tunable than the previous Mugen clutch. This clutch features a 34mm aluminum 4 shoe flywheel with removable steel pins and offers a unique way of adjusting spring tension to tune the engagement to suit your engine, track conditions and personal preference, to optimize fuel consumption and performance. The package includes .95 springs, two carbon shoes and two aluminum shoes, as well as a vented 13 tooth clutch bell and the rest of the parts needed for installation.
