Wiseco Chevy Big Block 4.615in Bore 1.060in CH 45.00 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 and 1.060-inch compression height are key dimensions for achieving the right compression ratio and valve clearance in your build. Wiseco machines these pistons in the USA, ensuring precise manufacturing for critical components like the ring grooves, which feature additional sealing improvements and anti-detonation designs to handle the demands of heavy to severe duty racing applications.

Beyond the core forging and machining, these pistons come with an ArmorGlide skirt coating. This isn't just for looks; it's designed to reduce friction, resist seizure, and contribute to quieter operation, all while handling the extreme conditions of racing. The fully machined crown and forced pin oiling further demonstrate the attention to detail in these Professional Series pistons, making them a solid choice when you're pushing the limits of your engine.

This set includes eight pistons, ready for your next engine build. Please note that these pistons are not CARB approved and cannot be shipped to California. It's always a good idea to consult your engine builder or a trusted mechanic to ensure these specifications align with your specific build goals.
