You have just purchased the BEST adjustable cam sprockets available. These AEM billet aluminum adjustable cam gears are CNC machined from billet aluminum and then laser etched with cam timing marks for adjustment up to ±10° at the cam or ±20° at the crankshaft. Using the vernier scale on the sprocket hub helps to do the cam timing changes quickly and accurately. The inner hub is anodized for lasting beauty and resistance to corrosion. The out gear sector is hard anodized for resistance to wear.
