1. A method of decreasing noise, vibration and harshness within a chain system comprising:
determining chain related orders at which noise, vibration and harshness occurs within the chain system;
determine which chain related orders at which noise, vibration and harshness were determined to occur to avoid increasing;
creating a pattern for application to a face of a tensioner, guide or snubber comprising a plurality of grooves separated by spacers having a width, with the plurality of grooves and spacers at an angle relative to first and second edges of the face, wherein the pattern includes a pattern engagement dimension that does not equal a multiple of pitch and an integer or a multiple of pitch and 1 over an integer, such that the face of the tensioner, guide or snubber engages with a chain of the chain system of at least one chain order other than the chain related orders at which noise, vibration and harshness were determined to occur to avoid increasing; and
applying the pattern to the face of the tensioner, guide or snubber.
