Wiseco Chevy Big Block 4.600in Bore 1.215in CH 48.70 CC Piston Set

Forged from 2618 aluminum, these Wiseco pistons are built for the demands of serious racing and heavy-duty performance applications. The 4.600-inch bore size is specific to Chevy Big Block engines, and the 1.215-inch compression height is a key measurement for determining your engine's final compression ratio. Wiseco machines these pistons in the USA, ensuring precise tolerances for critical components like the ring grooves, which feature anti-detonation designs and additional features for improved ring seal.

Beyond the core forging and machining, these pistons include an ArmorGlide skirt coating. This isn't just for looks; it's designed to reduce friction, resist seizure, and contribute to quieter operation, all important factors when you're pushing an engine hard. The fully machined crown and forced pin oiling further underscore the attention to detail in these Professional Series pistons, making them a solid choice for builders who need reliability under severe stress.

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. Always refer to the manufacturer's installation instructions for proper fitment and assembly procedures.
