Wiseco Pro Tru Street Chevy Big Block 4.155in Bore 1.760in CH 21.00 CC Piston Set

When you're rebuilding your Chevy Big Block, this Wiseco Pro Tru Street piston set gives you everything you need to get started. You get a full set of eight pistons, forged from 4032 alloy aluminum right here in the USA. This kit is designed to be an all-inclusive solution, so it comes complete with the necessary rings, pins, and clips to get your engine back together.

These pistons feature an ArmorGlide skirt coating, which helps reduce friction for quieter operation and resists seizing. The dome itself is AS-Forged, meaning it's shaped during the forging process for improved strength and includes features for oil drain-back. The included piston pins are made from chromium alloy steel, and Spirolox clips are used to secure them, ensuring a solid connection. The 4.155-inch bore size is specific for certain Big Block Chevy applications, and the 1.760-inch compression height is a key measurement for setting up your engine's valve timing and piston-to-head clearance.

Keep in mind that these pistons are not CARB approved, so they cannot be shipped to California. If you're looking for a well-built, comprehensive piston set for your street or track build, this Wiseco Pro Tru Street kit offers a lot of value with its included components and advanced features.
