Wiseco Chevy LT1 4.070in Bore 1.105in CH -6.90 CC Piston Set

Forged from 2618 aluminum, these Wiseco pistons are built to handle the demands of serious racing applications. The 4.070-inch bore size is specific for Chevrolet LT1 engines, and the -6.90cc dish volume is designed to work with specific cylinder head combinations to achieve your desired compression ratio. Wiseco engineers these pistons with precision ring grooves, anti-detonation grooves, and other features to ensure improved ring seal and durability under extreme conditions.

The ArmorGlide skirt coating on these pistons helps reduce friction and noise while also resisting seizure, which is crucial for longevity in high-performance builds. The fully machined crown ensures accuracy and consistency, and the forced pin oiling feature keeps the wrist pin lubricated, reducing wear. This set includes eight pistons, designed for heavy to severe duty performance builds where reliability and strength are paramount.

When rebuilding your LT1 engine for racing or extreme performance, these Wiseco Professional Series pistons offer a well-built foundation. Remember that these pistons are not CARB approved and cannot be shipped to California. Always refer to the manufacturer's installation instructions for proper fitment and assembly procedures.
