Wiseco Chevy LT1 4.065in Bore 1.105in CH -6.90 CC Piston Set

Forged from 2618 aluminum right here in the USA, these Wiseco pistons are built for serious performance in your Chevy LT1 engine. The 4.065-inch bore size and 1.105-inch compression height are key dimensions for rebuilding or upgrading your V8, and Wiseco machines them with precision for a solid fit and reliable operation. They're designed to handle the demands of heavy to severe duty racing applications, so you know they're built tough.

Wiseco includes several features to improve performance and durability. You'll find precision ring grooves, anti-detonation grooves, and other features aimed at improving ring seal. The piston crown is fully machined for a clean combustion chamber surface, and they come with forced pin oiling to keep the wrist pins well-lubricated under high stress. Plus, the ArmorGlide skirt coating helps reduce friction and noise while resisting seizure, which is a big help during break-in and hard running.

This set includes eight pistons, ready to be installed in your LT1 build. 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.
