Crower makes a stroker crank and so does Moldex. But be prepared to WAIT!!! I ordered a billet stroker crank from Moldex last August with a promised delivery time of about 12 weeks. Well, it's been 9 months and still no crank. Oh yeah, don't let them talk you into making a big deposit. They may make the best cranks on the market, but they are also the slowest to manufacture them.
