Wiseco Pro Tru Street Chevy Small Block 4.155in Bore 1.125in CH 8.00 CC Piston Set

Wiseco is well-known for making strong, reliable forged pistons for a wide range of performance applications. Their Pro Tru Street series pistons are built for drivers who want a solid upgrade for their Chevy small block engine, whether for daily driving or hitting the track. This set is specifically designed for a 4.155-inch bore, offering a complete solution for your engine rebuild.

These pistons are forged from 4032 alloy aluminum right here in the USA, which is a strong material choice for performance engines. They come with an ArmorGlide skirt coating that helps reduce friction, resist seizure, and makes for quieter operation compared to uncoated pistons. The dome features are AS-Forged, meaning they are shaped during the forging process, and include oil drain-backs to help manage oil flow. You also get a chromium alloy steel piston pin and Spirolox clips, so this set is ready for installation right out of the box.

This piston set is intended for a 4.155-inch bore with a 1.125-inch compression height and uses a 0.927-inch pin diameter. It's important to note that this part is not CARB approved and cannot be shipped to California. For a complete engine rebuild, ensure you have all the necessary supporting components and refer to the manufacturer's installation instructions for proper fitment and assembly.
