Just get the jackshaft, chaincase, driveshaft and secondary clutch out of any Phazer, Phazer II or 485 Venture and bolt it in.
Direct bolt in to an Ovation. Gets you the 2.52 drivers, stronger chaincase and better secondary.

Is the Phazer chaincase/secondary needed when only running a 121" was thinking it would definitely be a must running longer tracks
