Product Overview

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.

*Features*
• 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 and
exhaust valve overlap. More fuel and air equals more horsepower!
• 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 potential.
• Precision machined ring grooves with proper orifice/accumulator volume feature calculated groove root diameters and axial widths, providing
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 seal.

*ArmorGlide Skirt Coating*
Wiseco's 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 wear resistance.

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 pistons.

• ArmorGlide Skirt Coating: seizure resistant, friction reduction, and quieter operation
• Designed and built to withstand heavy to severe duty performance applications
• Engineered, forged, and machined in the USA from 2618 aluminum for improved tensile strength
• Forced pin oiling
• Fully machined crown features
• Precision ring grooves, anti-detonation groove, and additional ring seal improving features

Note for Pistons, Rings, Rotors, Rods and engine internals

Unless otherwise specified, some brands supply brake rotors, pistons, strut mounts, rods and rings separately. In some cases, titles may indicate plural, or 'set' - eg the term “ring set” often refers to the rings for a single piston only. If you’re unsure about what’s included with this product, please contact our team for clarification.

Reference Information

Pistons and Rings, Forged, Flat, 4.130 in. Bore, Chevy, Kit

Wiseco pulled out all of the stops with their Professional Series piston kits. These pistons accommodate the reluctor ring on stroker cranks without having to notch the pin bosses. Offset pins like OE and skirt shapes are specifically designed for street applications, making these the best piston kits available. Successfully tested in the highest horsepower applications, the Professional Series kits also utilize ArmorGlide skirt coating—which is the result of testing, development, and benchmarking through Wiseco's in-house dyno program. The outcome is minimized friction, maximized horsepower, and improved wear resistance. 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. Anti-detonation and pressure seal grooves give you a better ring seal, reducing noise from the piston rock and delivering better performance. Order the pistons tailored for your application.
