Wiseco Chrysler Big Block Mopar 383/400/440 Flat Top 4.375 Bore 3.750 Stroke +6cc Volume Piston Set

This piston set from Wiseco includes eight forged pistons, designed for Chrysler's Big Block 383, 400, and 440 cubic inch engines. These are flat-top pistons with a 4.375-inch bore and a 3.750-inch stroke, featuring a +6cc volume in the crown. They are built for serious racing and heavy-duty applications where durability and performance are critical.

Crafted from 2618 aluminum in the USA, these pistons are forged and machined for improved tensile strength, making them well-suited for severe duty performance builds. They come with precision ring grooves, anti-detonation grooves, and features designed to enhance ring seal. The piston crowns are fully machined, and they include forced pin oiling for better lubrication. Additionally, an ArmorGlide skirt coating is applied to reduce friction, resist seizure, and contribute to quieter operation.

This set is intended for builders who are assembling a high-performance engine and need pistons that can withstand demanding conditions. Please note that these pistons are not CARB approved and cannot be shipped to California. Always refer to the manufacturer's installation instructions for proper assembly and break-in procedures.
