Wiseco Chevy Small Block 4.060in Bore 1.550in CH -5.00 CC Piston Set

If you're building a high-performance Chevy Small Block engine, this set of eight forged pistons from Wiseco is designed to handle serious power. These pistons are made in the USA from 2618 aluminum, which offers improved tensile strength for demanding applications. The bore size is 4.060 inches, with a compression height of 1.550 inches and a dish volume of -5.00cc, which is important for setting your compression ratio.

Wiseco has packed these pistons with features for durability and performance. You'll find precision ring grooves, anti-detonation grooves, and other features aimed at improving ring seal. The piston crown is fully machined, and they include forced pin oiling to keep the wrist pins lubricated under high stress. The ArmorGlide skirt coating helps reduce friction, resist seizure, and operate more quietly, which is a notable benefit in a high-performance build. These are built to withstand heavy to severe duty race applications.

This set includes eight pistons, the wrist pins, and rings. Remember that these pistons are not CARB approved and cannot be shipped to California. For a serious engine build, these Wiseco pistons are a solid option.
