adjustable cam gear - M10 (double row) We use this adjustable cam gear to adjust cam timing and to make sure we have ample piston to valve clearance on race motors. You can also move the power band slightly by changing cam timing (provided that you have the necessary piston to valve clearance to do so). Our sprocket moves the timing either -1.5, +1.5 or +2.5 degrees. NOTE: Given the rising cost of the OEM cam gear, this serves as a great replacement option.
