Wiseco Chevrolet Small Block 4.155in Bore 1.425in CH -5.00 CC Pro Tru Street Piston Set

Wiseco is well-known for making strong, reliable forged pistons that perform well on the street and at the track. This Pro Tru Street piston set is built for Chevrolet Small Block engines and is designed to be a complete solution for your rebuild.

These pistons are forged from 4032 alloy aluminum, a material chosen for its good balance of strength and lighter weight compared to cast aluminum. The ArmorGlide skirt coating is applied to reduce friction, which can help with quieter operation and resist seizure. The dome features are AS-Forged, meaning they are shaped during the forging process, and include oil drain backs to help manage oil flow. This set comes with everything you need to get started: the pistons themselves, chromium alloy steel piston pins, and Spirolox clips.

This is a set of 8 pistons, each with a 4.155-inch bore and a 1.425-inch compression height. The dish volume is -5.00 CC, which will affect your compression ratio depending on your cylinder head volume. Please note that these pistons are not CARB approved and cannot be shipped to California. Always refer to the manufacturer's installation instructions for proper fitment and assembly details.
