Wiseco Pro Tru Street Chevy Big Block 4.250in Bore 1.645in CH -3.00 CC Piston Set

If you're rebuilding the heart of your Chevrolet Big Block, like a 454, a solid set of pistons is where it all starts. These Wiseco Pro Tru Street pistons are built for the demands of street use, offering a well-built foundation for your engine project. They're forged from 4032 alloy aluminum right here in the USA, which means they're strong and ready to handle the power you're looking for.

What sets these apart is the ArmorGlide skirt coating. It's designed to resist seizure, cut down on friction, and even make the engine run quieter, which is a nice bonus for a street-focused build. The pistons also feature an AS-forged dome with oil drain-backs, helping to manage heat and lubrication. This set comes complete with chromium alloy steel piston pins and Spirolox clips, so you get everything you need for installation in one box, making your rebuild more straightforward.

This is a complete set of 8 pistons, designed for a 4.250 inch bore with a 1.645 inch compression height. Remember, these are not CARB approved and cannot be shipped to California. Always refer to the manufacturer's installation instructions for proper fitment and assembly procedures.
