LS2/LS3/LSA/LS9/L99 Icon Forged Pistons 4.000″ Bore, 4.000″ Stroke, 6.125″ Rod w/.927″ PIN

ICON forgings are created at their in-house facility, utilizing the latest innovations in piston forging technology. Each ICON piston is purpose built from the ground up for extreme high-performance street or racing applications. From the FHR series to the LCAT, ICON offers the most diverse and fully-featured “Off the Shelf” forged piston on the market today. No matter what your high-performance application calls for, there is an ICON piston for you.

FHR (Formed Head Relief) line of pistons delivers professional quality on an enthusiast budget. FHR pistons have valve reliefs that are formed into the piston as the forging blank is pressed into the die. Many of the FHR dome pistons feature a solid dome, which gives engine builders the flexibility to machine the dome to their desired compression ratio.

Built from 11% silicon 4032 aluminum, FHR pistons can be installed with tighter piston to wall clearance for quiet operation and increased piston stability. In addition, the use of 4032 aluminum decreases the friction created during engine operation, this results in extended piston life and reduced wear.

Does not include rings.
