This very nice 22lb steel flywheel is made by SPEC Clutches and designed for a 10.5" clutch setup. It is the 153 tooth ring gear. If you wish for something lighter check out the 12lb aluminum version also in our store!
** Please note that I have been having some delivery problems with SPEC. Sometimes I end up with a 2-day lead time, but it has taken as long as two weeks to recieve any shipments from them. **
