Wiseco Pro Tru Street Buick 455 4.330in Bore 1.900in CH -27.00 CC Piston Set

This Wiseco Pro Tru Street piston set gives you everything you need to rebuild your Buick 455 engine. You get a complete set of eight pistons, along with the necessary rings, pins, and clips, all included for a straightforward rebuild. These pistons are forged from 4032 alloy aluminum right here in the USA, ensuring a well-built foundation for your engine project, whether it's for daily driving or hitting the track.

Wiseco's Pro Tru Street pistons feature an ArmorGlide skirt coating. This isn't just for looks; it's designed to resist seizure, reduce friction between the piston and cylinder wall, and contribute to quieter engine operation. The AS-forged dome includes features for oil drain-back, and each piston comes with a chromium alloy steel pin and Spirolox clips for secure assembly. The bore size is 4.330 inches, with a compression height of 1.900 inches, and a dish volume of -27.00 CC, making them suitable for specific engine builds where precise compression ratios are key.

Keep in mind that these pistons are not CARB approved and cannot be shipped to California. Always refer to the manufacturer's installation instructions for proper assembly and break-in procedures to get the most out of your new Wiseco pistons.
