Wiseco Chevy Small Block 4.035in Bore 1.550in CH 13.50 CC Piston Set

Wiseco is well-known for making strong, reliable internal engine components, especially for high-performance applications. This Professional Series piston set is a prime example, built for Chevy small block engines with a 4.035-inch bore. If you're building a serious race engine or a heavy-duty performance street machine, these pistons are designed to handle extreme conditions.

Each piston is forged and machined in the USA from 2618 aluminum, a material chosen for its improved tensile strength under high stress. They feature precision ring grooves, an anti-detonation groove, and other features to improve ring seal, which is critical for power and longevity in demanding builds. The crown is fully machined for accuracy, and they come with forced pin oiling to ensure the wrist pin stays well-lubricated. Plus, the ArmorGlide skirt coating helps reduce friction, resist seizure, and operate more quietly, even under severe duty.

This set includes eight pistons, ready for your next engine build. Keep in mind these are not CARB approved and cannot be shipped to California. For builders aiming for maximum performance and durability in their Chevy small block, these Wiseco pistons are a solid choice.
