Ross pistons are high-quality racing pistons made of forged aluminum. As they are manufactured for use in high performance engines, Ross pistons are lighter and stronger than the cast aluminum pistons found in most family cars.
The average car or motorcycle engine functions equally well with expensive forged pistons or with less expensive cast pistons. These engines are not designed to generate explosive power, and most drivers do not notice any difference in performance.
Racing car engines, however, are designed to provide maximum acceleration and speed, and they require much stronger pistons. As with most racing components, lightweight materials are preferable. For the average street vehicle, there is usually a compromise to provide sufficient quality at the lowest prices.
Ross Racing Pistons has been in business since 1979, producing high-end pistons for high performance car and motorcycle engines.
