Wiseco Chevy Small Block 4.035in Bore 1.062in CH 13.50 CC Piston Set

Wiseco is well-known for making strong internal engine components, especially for performance applications. This Professional Series piston set is a prime example, designed for Chevy Small Block engines that demand serious durability. If you're building a high-performance engine for heavy or severe duty racing, these pistons are made to handle the stress.

These pistons are forged and machined right here in the USA from 2618 aluminum, which gives them improved tensile strength for high-stress environments. They feature precision ring grooves, an anti-detonation groove, and other features to help improve ring seal, keeping combustion pressure where it belongs. You'll also find an ArmorGlide skirt coating, which helps reduce friction, resist seizure, and contribute to quieter operation. The fully machined crown is ready for your build, and forced pin oiling ensures the wrist pin stays well-lubricated under extreme conditions.

This set includes eight pistons, each with a 4.035-inch bore and a 13.50cc dish volume, along with a 1.062-inch compression height and a 0.927-inch pin diameter. Please note that these pistons are not CARB approved and cannot be shipped to California.
