Wiseco Chevy Big Block 4.605in Bore 1.065in CH 15.60 CC Piston Set

If you're building a high-performance Chevy Big Block engine for serious racing or severe duty applications, a strong set of pistons is crucial. This Wiseco Professional Series piston set is designed to handle the extreme demands of competition. They're forged from 2618 aluminum, a material known for its improved tensile strength, making these pistons well-suited for the high stresses and temperatures found in race engines.

Wiseco has packed a lot of thought into these pistons. You'll find precision machined ring grooves, anti-detonation grooves, and other features aimed at improving ring seal, which is vital for both power and engine longevity. The piston crowns are also fully machined for a clean, consistent combustion chamber. To further reduce friction and improve durability, these pistons come with an ArmorGlide skirt coating, which helps prevent seizure and makes for quieter operation. Plus, the forced pin oiling ensures the wrist pin stays well-lubricated under extreme conditions.

This set includes eight pistons, designed for a 4.605-inch bore and featuring a 1.065-inch compression height. They are built to withstand heavy to severe duty performance applications, giving you the confidence to push your engine to its limits. Keep in mind that these pistons are not CARB approved and cannot be shipped to California.
