Grear with keyway. Incl. bolt; key; washer and three spacers. This Andrews 503576 gear is an improved design over the OEM style gear for 1999 only Twin Cams (which is no longer available from OEM). The 1999 OEM design is prone to broken woodruff key''s; when this happens the cams; and complete valve train; will stop in the still running engine. The Andrews gear and spacer is made from a 4 times stronger material than the OEM gear; and is of a one-piece design. This one-piece design enables the use of a full length .350" longer woodruff key; which improves strength. Note: Especially in high performance applications it is recommended to use the Andrews 503576 gear for 1999 Twin Cam models.
