Wiseco Chevy Small Block 4.060in Bore 1.000in CH -25.00 CC Piston Set

Forged from 2618 aluminum, these Wiseco pistons are built for the demands of serious racing and heavy-duty engine builds. The 4.060-inch bore size is a common upgrade for Chevy small blocks, and the 1.000-inch compression height combined with a -25.00cc dish volume is designed to achieve specific compression ratios when paired with the right cylinder heads and crankshaft.

Wiseco machines these pistons in the USA, incorporating features like precision ring grooves, anti-detonation grooves, and improved ring seal to ensure reliable performance under severe operating conditions. The crown is fully machined for accuracy, and forced pin oiling helps keep the wrist pins lubricated. Additionally, the ArmorGlide skirt coating helps reduce friction, resist seizure, and quiet down operation, which is a notable benefit for high-performance engines.

This set includes eight pistons, designed to withstand the rigors of severe duty race applications. While these pistons are built for extreme performance, remember they are not CARB approved and cannot be shipped to California. Always refer to the manufacturer's installation instructions for proper assembly and break-in procedures.
