Wiseco Pro Tru Street Chevy Big Block 4.500in Bore 1.645in CH -3.00 CC Piston Set

When you're rebuilding the heart of your Chevy Big Block, you want parts you can trust to perform. This Wiseco Pro Tru Street piston set is built for that purpose, giving you a solid foundation for your engine project. You get a complete set of eight pistons, ready to go into a 4.500-inch bore engine, with a 1.645-inch compression height and a -3.00cc valve relief volume. Everything you need to get started is included right in the box: the pistons themselves, high-strength chromium alloy steel piston pins, Spirolox retaining clips, and a full set of rings.

These pistons are forged from 4032 alloy aluminum right here in the USA, a material known for its strength and durability, especially when dealing with the heat and pressures of a performance engine. Wiseco also applies their ArmorGlide skirt coating, which is designed to reduce friction, resist seizure, and even help quiet down operation. The dome design features oil drain-backs and specific crown features to help manage combustion and heat.

This set is designed for street performance, aiming to get you on the road or down the track reliably. Keep in mind that these pistons are not CARB approved and cannot be shipped to California. For a complete rebuild, ensure you have all other necessary components like gaskets, bearings, and a crankshaft.
