This adjustable cam sprocket allows precise cam timing without elongating bolt holes. It also allows advancing or retarding the cam to tune the power range with engraved timing marks to show degrees of advance/retard. The sprocket teeth have been induction hardened to increase durability. Includes hardened adjustable cam sprocket, hardened crank sprocket, tensioner and Renold chain.
Fit Note: The original Triumph GT6 sprockets and chain are single-row. This double-row timing set may be used as an upgrade.
