Wiseco Chevrolet Big Block 4.310in Bore 1.645in CH 21.00 CC Pro Tru Street Piston Set

When you're rebuilding the heart of your Chevrolet Big Block, you want parts you can trust. This Pro Tru Street piston set from Wiseco gives you everything you need to get your engine back in action. You'll find eight forged pistons, complete with rings, pins, and clips, all ready for installation. These pistons are forged from 4032 alloy aluminum right here in the USA, ensuring a well-built component for your build.

Wiseco's Pro Tru Street series is designed for a balance of performance and everyday drivability. The pistons feature an AS-Forged dome with specific crown features and oil drain-backs, which helps manage combustion and oil flow. They also come with an ArmorGlide skirt coating. This coating is notable for reducing friction, which can lead to quieter operation and improved resistance to seizure, especially during the critical break-in period and under normal driving conditions. The included chromium alloy steel piston pins and Spirolox clips are built to handle the stresses of a performance engine.

This set is specifically for a 4.310-inch bore with a 1.645-inch compression height and uses a 0.990-inch pin diameter. Keep in mind that these pistons are not CARB approved and cannot be shipped to California. For a complete rebuild, this set provides a solid foundation for your engine project.
