Wiseco Big Block Mopar 383/400/440 Flat Top Pistons (Qty 8)

If you're building a high-performance Big Block Mopar engine for serious racing or heavy-duty use, you need pistons that can handle the stress. These Wiseco Professional Series flat-top pistons are forged from 2618 aluminum, a material chosen for its improved tensile strength, making them well-suited for the demands of severe duty applications. They are designed and machined right here in the USA, ensuring a high level of precision throughout the manufacturing process.

Wiseco has packed these pistons with features to enhance both performance and durability. You'll find precision ring grooves, anti-detonation grooves, and other features designed to improve ring seal, which is critical for maintaining compression and preventing blow-by under extreme conditions. The fully machined crown ensures consistent combustion chamber volume, and the forced pin oiling system helps keep the wrist pins lubricated. Additionally, the ArmorGlide skirt coating helps reduce friction, resist seizure, and contribute to quieter operation, even in demanding builds.

This set includes eight pistons, enough for a complete V8 engine. While these pistons are built for extreme performance, remember they are not CARB approved and cannot be shipped to California. Always refer to the manufacturer's installation instructions for proper fitment and assembly procedures.
