Wiseco - Forged Pistons

Founded in 1940 by Clyde Wiseman in his Cleveland garage, Wiseco pioneered performance pistons to win marine races, evolving into a global leader over 80+ years later. The company remains rare among aftermarket brands—manufacturing exclusively forged pistons from premium alloys using in‑house forging presses and CNC machines at its Mentor, Ohio facility.

Wiseco offers full piston kits across three automotive series: Pro Tru Street (4032 alloy, light-duty up to 750 hp), RED Series (2618 alloy, horizontal pin oiling, up to 1,000 hp), and Professional Series (forced pin oiling, gas ports, customizable for 1,500+ hp builds). Each kit includes coated pistons, precision-engineered rings, pins, and clips—ready for install from the box.

Engineered for durability, power, and efficiency, Wiseco pistons feature ArmorGlide skirt coatings, precision ring grooves, optional ceramic crowns, and specialized forging grain structure to resist detonation and maximize performance. Supporting everything from Harley and ATV engines to street, drag, oval, and circle‑track setups, Wiseco continues championing race-proven quality and American manufacturing.
