Wiseco Chevy Small Block Pro Tru Street 4.165in Bore Piston Kit

If you're rebuilding the engine in your Chevy Small Block, getting the right pistons is a critical step for performance and longevity. This Pro Tru Street piston kit from Wiseco is built for those who want a solid foundation for their street-driven or track-ready machine. They are forged from 4032 alloy aluminum, a material known for its strength and durability, making them a well-built choice for a performance rebuild.

Wiseco manufactures these pistons in Ohio, and they come as a complete set for an 8-cylinder engine, including everything you need to get started: the pistons themselves, high-quality chromium alloy steel pins, Spirolox clips, and a set of rings. The pistons feature an AS-Forged dome with specific crown features designed to help with oil drain-back, and they also include an ArmorGlide skirt coating. This coating is notable for reducing friction, which can lead to quieter operation and improved resistance to seizing, especially important in street applications where engine loads can vary.

With a 4.165-inch bore and a 1.125-inch compression height, these pistons are designed to fit specific Small Block Chevy configurations. It's important to note that these pistons are not CARB approved and cannot be shipped to California. Ensure you check all manufacturer specifications and installation guidelines before beginning your engine build.
