Wiseco Chrysler HEMI 426 4.310in Bore 1.765 Compression Height +80cc Dome Top Pistons

If you're building a high-performance Chrysler 426 Hemi engine for serious racing or heavy-duty applications, these Wiseco Professional Series pistons are a solid choice. They're designed to handle the extreme demands of competition, offering improved strength and durability where it matters most. Wiseco crafts these pistons from 2618 aluminum, a material known for its excellent tensile strength, making them well-suited for the intense pressures and heat generated in a race engine.

These pistons feature a +80cc dome top, which is important for achieving the desired compression ratio with specific cylinder head volumes. The 4.310-inch bore size and 1.765-inch compression height are critical dimensions for proper engine assembly and performance tuning. Wiseco also includes precision ring grooves, anti-detonation features, and additional ring seal improvements to ensure optimal combustion and prevent blow-by. The fully machined crown and forced pin oiling further contribute to their robust design for severe duty use. Additionally, the ArmorGlide skirt coating helps reduce friction and resist seizure, contributing to a quieter operation and longer piston life under stress.

This set includes eight pistons, ready for your next engine build. Keep in mind that these pistons are not CARB approved and cannot be shipped to California. For a successful installation, always refer to the manufacturer's detailed specifications and recommended assembly procedures.
