Wiseco Chevy Big Block 4.615in Bore 1.155in 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 is specific for certain Big Block applications, and the 1.155-inch compression height works with many popular crankshafts. These aren't your average replacement pistons; they're designed for the demands of heavy to severe duty racing builds where durability and consistent performance are critical.

Wiseco machines these pistons in the USA, paying close attention to details like precision ring grooves, anti-detonation features, and additional ring seal improvements. The crown is fully machined for accuracy, and they incorporate forced pin oiling to keep the wrist pins well-lubricated under high stress. You'll also find an ArmorGlide skirt coating, which helps reduce friction, resist seizure, and contribute to quieter operation, even in demanding conditions.

This set includes eight pistons, ready to be installed in your performance engine build. Remember 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.
