JE Pistons FSR Superfly GP pistons are the ultimate lightweight pistons for late model stock 2-barrel and similar applications up to 400 hp. FSR forging provides reduced skirt contact that lowers friction for optimum horsepower gains. These pistons feature a .190 in. deep intake valve pocket for maximum compression. The ring grooves are machined for 1.2, 1.2, 3.0mm backcut rings with lateral gas ports for superior ring seal.
