Wiseco Chevy Big Block 4.280in Bore 1.645in CH 32.00 CC Piston Set

Wiseco is well-known for making strong, reliable engine components, especially for high-performance applications. This Professional Series piston set is built for serious racers and builders who need top-tier performance and durability in their Chevy Big Block engines. These aren't your average pistons; they're designed and machined in the USA from 2618 aluminum, which gives them improved tensile strength to handle the demands of heavy to severe duty race builds.

You'll find precision ring grooves, anti-detonation grooves, and other features aimed at improving ring seal, which is crucial for consistent power and engine health under extreme conditions. They also come with an ArmorGlide skirt coating. This coating helps reduce friction, resist seizure, and makes operation quieter, all contributing to a more efficient and longer-lasting engine. The fully machined crown ensures accuracy and proper combustion chamber shape.

This set includes eight pistons, each designed with forced pin oiling to ensure the wrist pin stays well-lubricated. If you're building a powerful Chevy Big Block for racing or severe duty, these pistons are a solid option to consider for removing your limits.
