World renowned for their work building race winning pistons,
Wiseco utilizes experience from a diverse background of the most
sophisticated engines in such venues as Formula 1, Indy Racing
League (IRL), NHRA Pro Stock, Moto
GP, AMA Superbike, AMA
Motocross and Supercross to design and manufacture the highest
technology pistons available.
- Valve Pocket designs that allow maximum flow around valve, also
allowing oversized valves and high lift cams to be utilized.
- Piston Crown shapes designed to promote maximum Intake Charge
efficiency through scavenging mixture Cross Flow during intake
exhaust valve overlap. More fuel and air equals more
- Piston Domes designed for optimal quench during the
compression/ combustion cycle, resulting in resistance to
detonation and preignition.
The end result is longer engine life and increased horsepower
- Precision machined ring grooves with proper orifice/accumulator
volume feature calculated groove root diameters and axial widths,
excellent surface finish and flatness, maximum ring seal and
minimized blow-by and oil consumption.
- World class, ISO Certified, forging facility that
utilizes the latest technologies Featuring complex forged shapes,
advanced materials, and feature-aligned grain flow technology.
- Complex Piston skirt profiles that reduce power robbing
friction, yet promote stability in the bore for optimum ring
ArmorGlide Skirt Coating
Wisecos new ArmorGlide skirt coating is the result of testing,
development, and benchmarking through our in-house dyno program.
The outcome minimized friction, maximum horsepower, and improved
Not only is ArmorGlide a high-tech lubricant that reduces
friction, but it also allows the piston to be fitted tighter within
the bore than a non-coated piston. Better ring seal reduces noise
from piston rock. ArmorGlide is being applied to selected
