The piston pin boss is machined to accept the width of the rod and a pair of spacers giving .005/.007 side clearance. This centers the rod on the crank and allows the width of the big end to be reduced by .080 per side, resulting in lighter rods. Less rod weight equals a lighter crank to achieve balance. Net result is an overall lighter assembly.
