These pistons feature a unique Moly coating on the skirts which allows the builder to run a much closer piston to bore tolerance then he might do on another make of piston (typical clearance is just 0.08 although please check with us first!). This helps remove the slapping noise during cold start, common place among engines running forged pistons due to larger then OE bore clearances. The crowns of the pistons are also mirror polished to better resist detonation on a high performance engine. Mirror polishing allows a more even spread of heat inside the chamber which will help prevent “hot spots” on piston crowns. Price includes all piston rings and gudgeon pins. No need to purchase extras, this package allows you to fit Forged pistons seamlessly.
