Wiseco Chevy Big Block 4.310in Bore 1.270in CH 45.00 CC Piston Set

If you're building a high-performance Chevrolet Big Block engine for serious racing or heavy-duty applications, these Wiseco Professional Series pistons are a solid choice. They're designed from the ground up to handle the extreme demands of competition, offering a blend of strength, durability, and advanced features that help you push your engine's limits.

These pistons are forged and machined in the USA from 2618 aluminum, a material known for its improved tensile strength, which is crucial for withstanding the high pressures and temperatures found in race engines. Wiseco has incorporated several features to enhance performance and longevity, including precision ring grooves, anti-detonation grooves, and additional ring seal improvements. The crown of each piston is fully machined for accuracy, and they come with forced pin oiling to ensure the wrist pins stay well-lubricated under stress. Plus, the ArmorGlide skirt coating helps reduce friction, resist seizure, and operate more quietly, which can make a difference in overall engine efficiency and lifespan.

This set includes eight pistons, each designed for a 4.310-inch bore with a 1.270-inch compression height and a 0.990-inch pin diameter. Keep in mind that these pistons are not CARB approved and cannot be shipped to California. For builders aiming for maximum performance and reliability in severe duty race applications, this Wiseco set offers a well-built foundation.
