Wiseco is a historic American manufacturer (established in 1941 in Mentor, Ohio), recognised as the worldwide reference in high performance forged pistons for motorsport applications. Wiseco pistons are forged from aerospace-grade aluminium, a process that compresses the material molecules to achieve superior density and increased resistance to impact and fatigue, essential for engines running high compression and high RPM.

Important: 13.5:1 compression ratio intended for built engines running suitable fuel (high octane petrol, methanol or ethanol depending on the build). Verify piston-to-wall clearances and ring end gaps before assembly per Wiseco recommendations. Installation requires a properly prepared engine (block bored to correct diameter, cylinder head preparation).
