Wiseco Chevy SB 23 Degree Turbo Supercharger Dish Piston Shelf Stock Kit

Wiseco is well-known for making strong, reliable forged pistons that serious racers and builders trust. This Professional Series piston set is a prime example, built for demanding Chevrolet Small Block applications, especially those involving turbochargers or superchargers. These aren't your average pistons; they're designed from the ground up to handle the extreme pressures and heat that come with high-performance forced induction setups.

Each piston in this set is forged and machined in the USA from 2618 aluminum, a material chosen for its improved tensile strength under high stress. You'll find precision ring grooves, an anti-detonation groove, and other features aimed at improving ring seal, which is critical for preventing blow-by and maintaining power. The crown is fully machined for accuracy, and they come with forced pin oiling to ensure the wrist pins stay well-lubricated. Plus, the ArmorGlide skirt coating helps reduce friction, resist seizure, and keep operation quieter, even under severe duty conditions. This kit is intended for heavy to severe duty performance builds where reliability and durability are paramount.

This set includes eight pistons, each with a 4.030-inch bore and a 1.250-inch compression height, using a 0.927-inch pin diameter. Please note that these pistons are not CARB approved and cannot be shipped to California. If you're building a high-performance Chevy SB engine for racing or extreme street use, this Wiseco piston set offers a well-built foundation.
