Wiseco Chevy Small Block 4.030in Bore 1.250in CH -1.70 CC Piston Set

What you get in this Wiseco Professional Series piston set is a complete package for rebuilding your Chevy small block engine, designed for serious performance applications. This set includes eight forged pistons, each precision-machined to a 4.030-inch bore size, with a 1.250-inch compression height and a -1.70cc dish volume. These aren't just standard pistons; they're built from 2618 aluminum, chosen for its improved tensile strength, and forged right here in the USA.

Wiseco has packed these pistons with features aimed at durability and performance under heavy loads. You'll find precision ring grooves, anti-detonation grooves, and other features designed to improve ring seal, which is critical for preventing blow-by and maintaining compression. The crown of each piston is fully machined, and they come with forced pin oiling to ensure the wrist pins stay well-lubricated. Plus, they feature an ArmorGlide skirt coating, which helps reduce friction, resist seizure, and contribute to quieter operation. These pistons are engineered to handle severe duty race builds, meaning they're built tough for demanding conditions.

Keep in mind that these pistons are not CARB approved and cannot be shipped to California. If you're building a high-performance engine for racing or heavy-duty use, this Wiseco set is a well-built option designed to withstand the stress.
