Wiseco Chevy LT1 4.070in Bore 1.105in CH -20.00 CC Piston Set

Forged from 2618 aluminum, these Wiseco pistons are built for serious performance in Chevy LT1 engines. The 4.070-inch bore size and -20.00cc dish volume are key specifications for builders looking to achieve specific compression ratios and displacement targets in their high-performance or racing applications. Wiseco's Professional Series is designed for builders who demand durability and performance without compromise, intended for heavy to severe duty use where reliability is paramount.

These pistons feature a fully machined crown and precision ring grooves, including anti-detonation features and additional ring seal enhancements to ensure optimal combustion control and power delivery. The ArmorGlide skirt coating is applied to reduce friction, resist seizure, and contribute to quieter operation, all crucial for engines pushed to their limits. Forced pin oiling is also incorporated to ensure the wrist pin receives adequate lubrication under extreme conditions.

This set includes eight pistons, each designed and machined in the USA. While these pistons are built for extreme performance, please note they are not CARB approved and cannot be shipped to California. For builders aiming for a robust and powerful LT1 engine, this Wiseco set offers a well-built foundation.
