Wiseco Chevrolet LT1 6.2L 4.065 Bore 1.115 Comp Ht. 4.000 Stroke 6.125 Rod -20cc

Forged from 2618 aluminum, these Wiseco Professional Series pistons are built for the demands of serious racing and performance engine builds. They feature a 4.065 inch bore and are designed to work with a 4.000 inch stroke and a 6.125 inch rod, with a compression height of 1.115 inches and a -20cc dish volume. This specific design is intended for Chevrolet LT1 6.2L engines that are being pushed to their limits.

Wiseco machines these pistons in the USA, incorporating features like precision ring grooves, anti-detonation grooves, and additional ring seal improvements to ensure reliable performance under extreme conditions. The crown is fully machined for accuracy, and forced pin oiling helps keep the wrist pins lubricated. Additionally, an ArmorGlide skirt coating is applied to reduce friction, resist seizure, and contribute to quieter operation, all crucial for engines subjected to heavy or severe duty use.

This set includes eight pistons, designed to be a complete solution for rebuilding or upgrading your LT1 engine. 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 fitment and assembly procedures.
