Probe SRS 331 Dish Top Stroker Pistons 20.1cc

Probe Sportsman Race Series forged pistons are designed for serious street and most track applications, although we find they work extremely well even in mild or stock replacement applications. SRS series pistons are manufactured from aircraft quality 2618 forgings, which provides very high strength. Probe's exclusive diamond cut skirt design allows piston to wall clearances suitable for even the mildest applications. Since Probe SRS forged pistons are substantially lighter than stock, engine balancing is an absolute requirement. SRS forged pistons use 1/16 ring sizes and full floating wrist pins.
