Racer Elite 4-stroke pistons are the first to be forged with a 2000-series alloy, providing greater tensile strength for full-race applications. The ArmorPlating surface treatment on the crown, ring groove, and pin bores protects against detonation, friction wear, and ring micro-welding. The ArmorFit skirt coating conforms to the cylinder bore, ensuring optimized fitment and performance. Racer Elite pistons are designed for those who demand the highest performance and reliability in racing conditions.
