The JE Pistons 377998R is a set of high-strength, lightweight pistons designed to reduce engine friction. These forged pistons feature a flat top with a -4.5cc dish and are intended for use with 13-degree cylinder heads from brands like All-Pro, Brodix, and Dart.

Each piston includes accumulator grooves, double pin oilers, and comes with round wire locks and wrist pins. The ring package size is .043in, .043in, 3.0mm (rings not included). This set is designed for a 4.135-inch bore size, a 3.750-inch crankshaft stroke, and a 6.000-inch rod length.
