Wiseco Chevy Small Block 4.165in Bore 1.062in CH -36.00 CC Piston Set

Forged from 2618 aluminum, these Wiseco pistons are built for the demands of serious racing and heavy-duty performance builds. The 4.165-inch bore size is specifically chosen for certain Chevrolet Small Block engine configurations where increased displacement is desired. This set includes eight pistons, each featuring precision machining for optimal performance and durability.

Wiseco has incorporated several advanced features into this Professional Series set. The pistons include precision ring grooves designed for improved sealing, an anti-detonation groove to help prevent detonation damage, and additional features to enhance ring seal. The crown is fully machined for a clean combustion chamber surface, and forced pin oiling helps keep the wrist pin and connecting rod small end lubricated under extreme conditions. Additionally, the ArmorGlide skirt coating reduces friction, resists seizure, and contributes to quieter operation, all crucial for engines subjected to severe duty.

This piston set is intended for builders who are pushing their engines to the limit. While these pistons are built for extreme performance, please note they are not CARB approved and cannot be shipped to California. Ensure you consult with your engine builder or refer to Wiseco's technical documentation for complete installation details and compatibility with your specific engine build.
