Made in the USAUpgrade your stock cast piston to a forged piston from Wiseco. Wiseco forged pistons add durability, and the precision demanded by high performance engines of every category. Forgings have condensed grain that is aligned to the features of the part, which produces higher mechanical properties, and resistance to impact and fatigue. Each forging is designed to optimize the strength-to-weight ratio, and maximize performance. Compared to cast pistons, forgings are tougher and more durable, and will stand up to the abuse of high RPM engines. Wiseco pistons are used in automobiles, motorcycles, ATV, outboard marine or anywhere superior quality is a must. Bailey’s now offers you this same quality for your chainsaw.
