Heavy-duty wrist pins with true 0.9270” diameter to fit rods correctly
Line2Line AST skirt coating starts out with a near-zero wall clearance and through the break-in period hones the cylinders to produce the correct oil wedge, keeping the piston square to the cylinder for best ring seal and quiet operation
