CP Pistons - Performance Pistons & Connecting Rods

Founded in 1963 by Fred Carrillo, CP‑Carrillo is a premier U.S. manufacturer of pistons and connecting rods—born from a commitment to performance without compromise. In 2008, CP Pistons joined forces with Carrillo, and today as part of Pankl Racing Systems, the company combines decades of motorsport heritage with advanced manufacturing in Irvine, California.

CP‑Carrillo engineers a complete lineup of high‑strength steel, titanium, and aluminum rods plus precision pistons—each CNC‑machined, heat‑treated, balanced to ±1 g, and dyno-tested before production. Their rods feature patented fasteners and I‑beam or H‑beam designs capable of enduring extreme RPM, boost levels, and abuse in drag, Pro Stock, boat, powersports, and street‑race engines .

Backed by ISO- and IATF-certified processes, multi-stage inspection, custom order capability, and real-world feedback from championship teams, CP‑Carrillo continues to elevate engine reliability and performance. Whether racing or building a high-output street car, their precision components deliver durability, power, and engineering excellence.
