Icon Formed Head Relief (FHR) series “Off the Shelf” pistons loaded with premium features found in custom made pistons. FHR pistons 4032 Alloy material has 11% silicon content which controls the thermal expansion so a tighter piston to wall clearance may be used over the 2618 alloy. The additional silicon will also increase wearability on the skirts and pin bores making this an ideal material for street and light boosted applications. FHR pistons have valve reliefs that are formed in as the piston blank is pressed into the die. Many of the domed models are solid which allows tailoring the dome height for a specific compression ratio. Check the dome style for specific dome description. Press or bushed connecting rods may be used as all applications come with lock rings.
