Wiseco Chevy LT1 4.125in Bore 1.115in CH -15cc Professional Dish Pistons - Set of 8

Forged from 2618 aluminum, these Wiseco Professional Series pistons are built for the demands of serious racing and heavy-duty performance builds. The 4.125-inch bore size is specific to certain Chevrolet LT1 engine configurations, and the -15cc dish volume is designed to achieve a particular compression ratio when paired with the right cylinder heads and crankshaft.

Wiseco machines these pistons in the USA, paying close attention to details like precision ring grooves, anti-detonation features, and enhanced ring sealing to ensure optimal performance and durability. The crown is fully machined for accuracy, and they include forced pin oiling to keep the wrist pins properly lubricated under high stress. Additionally, the ArmorGlide skirt coating helps reduce friction, resist seizure, and contribute to quieter operation, all crucial for engines pushed to their limits.

This set includes eight pistons, designed to withstand severe duty applications. 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 maximum performance and reliability in their LT1 engine, these Wiseco pistons offer a well-built foundation.
