Skunk2 Pro Series cam gear lets serious tuners dial camshaft timing +/-10 degrees to tailor the power curve on Honda D-series SOHC engines, with laser-etched timing marks for quick, accurate adjustment. The six-bolt design eliminates gear slip and the CNC-machined 7075-T6 billet aluminum construction (35% lighter than OEM) cuts rotational inertia for sharper response. Woodruff key not included (Honda PN 90741-667-000).
