Note for Pistons, Rings, Rotors, Rods and engine internals

Unless otherwise specified, some brands supply brake rotors, pistons, strut mounts, rods and rings separately. In some cases, titles may indicate plural, or 'set' - eg the term “ring set” often refers to the rings for a single piston only.

Pistons, Single - 350 SBC SPRFLY WT FT

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.
