Wiseco Chevy Big Block 4.615in Bore 1.060in CH 48.70 CC Piston Set

Forged from 2618 aluminum, these Wiseco pistons are built for serious performance in Chevy Big Block engines. The 4.615-inch bore size is specific for certain Big Block configurations, and the 1.060-inch compression height works with various crankshaft and rod combinations to achieve your desired deck height. Wiseco machines these pistons in the USA, ensuring precise tolerances for critical components like the ring grooves, which feature additional sealing improvements and anti-detonation designs to handle the stress of heavy or severe duty racing applications.

Beyond the core forging, Wiseco applies an ArmorGlide skirt coating. This isn't just for looks; it's a functional treatment that reduces friction between the piston skirt and cylinder wall, helps prevent seizure under extreme heat, and contributes to quieter operation. The fully machined crown and forced pin oiling further demonstrate the attention to detail in these pistons, all aimed at maximizing durability and performance when you're pushing your engine to its limits. This set includes eight pistons, ready for your next high-performance build.

Keep in mind that these pistons are not CARB approved and cannot be shipped to California. For builders aiming for the highest levels of performance and durability in their Chevy Big Block, this set offers a well-built foundation.
