Wiseco Professional Series forged racing pistons are engineered for serious racers and performance builders who demand reliable operation in heavy- to severe-duty applications. This Wiseco K0400X1 piston set is designed for Chrysler 6.2L Gen III Hemi Hellcat and Demon engines and includes eight pistons with premium rings for a complete high-performance piston solution.
Manufactured, forged, and machined in the USA from 2618 aluminum, these pistons provide improved tensile strength and durability for demanding race builds. The fully machined crowns support precise combustion chamber compatibility, while precision ring grooves, an anti-detonation groove, and additional ring-sealing features help promote consistent compression and dependable performance under high cylinder pressures.
Each piston incorporates Wiseco ArmorGlide skirt coating to help resist seizure, reduce friction, and minimize operating noise. Forced pin oiling further supports wrist pin lubrication during demanding use. With a 4.100-inch bore, 1.280-inch compression height, and 0.945-inch pin diameter, this set is a purpose-built choice for Chrysler 6.2L Hemi performance applications. This product is intended for competition and off-road use and is not approved for emissions-controlled street vehicles.
