Sized for a 4.125 in bore and 5.6 cc dome volume, this set delivers controlled compression for performance small-block builds. Manufactured from 2618 aluminum in the USA, the pistons employ Forged Side Relief forging to minimize skirt friction and weight; accumulator grooves and skirt coatings where applicable improve ring seal and reduce wear for consistent performance.
