Wiseco Chevy LT1 4.125in Bore 1.105in CH -10.00 CC Piston Set

If you're building a high-performance Chevrolet LT1 engine, this Wiseco forged piston set is designed to handle serious power. These pistons are specifically made for a 4.125-inch bore and feature a 1.105-inch compression height, which is crucial for achieving the correct compression ratio with your chosen cylinder heads and crankshaft. Wiseco builds these Professional Series pistons in the USA from 2618 aluminum, a material known for its improved tensile strength, making them well-suited for heavy to severe duty racing applications where reliability under extreme stress is paramount.

You'll find precision details throughout this set, including precisely machined ring grooves that ensure a good seal, an anti-detonation groove to help prevent detonation damage, and features that further improve ring seal. The pistons also come with an ArmorGlide skirt coating. This coating helps reduce friction, resist seizure, and contributes to quieter operation, all while handling the intense heat and pressure of a race engine. The fully machined crown ensures accuracy and consistency across the set, and forced pin oiling helps keep the wrist pins properly lubricated under high loads.

This set includes eight pistons, rings, and wrist pins, ready for your engine build. Keep in mind that these pistons are not CARB approved and cannot be shipped to California. For a robust and durable foundation for your LT1 performance build, this Wiseco set offers a well-built solution designed for the demands of racing.
