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.

These additional application notes are supplied by the manufacturer and collated from multiple year ranges. Not all of these notes may apply to every year or every variant. Please contact a StreetFX agent for clarification if required.

• 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, Quick 8 Series, Forged Aluminum, Dome, 4.610 in. Bore, Chevrolet, 7.4L, Set of 8

Wiseco Quick 8 Series pistons are targeted to support the ever-growing popularity of the Big Chief/Big Duke style engines. Whether it's in the Top Dragster/Sportsman categories of heads-up style shootouts, these pistons are designed to handle the job. With universal solid domes and valve pockets, eight part numbers cover 24 possible combinations. The finished product is flat top, dome, or dish compatible due to thicker decks. Purpose-built forgings were designed to handle the high horsepower loads of today's power adders, all the while keeping the weight down and preventing cracking. With four part numbers covering 12-14 degree applications, the Quick 8 Series will cover the majority of combinations widely in use. Never before has a shelf stock piston been available with such a "fits all" capability. Wiseco went to engine builders for input, loading this series with the best options available. Each piston utilizes gas ports, ArmorGlide skirt coating, strutted forgings, and the popular .043 in. x .043 in. x 3mm ring package. Wrist pins are heavy-duty .180 in. wall pins that can be upgraded to severe-duty pins, as needed. Order the model recommended for your year/make and engine application.
