Wiseco Chevrolet LS 3.903in Bore 1.335in CH 4.00 CC Pro Tru Street Piston Set

If you're rebuilding the engine in your Chevrolet LS vehicle, this Wiseco Pro Tru Street Piston Set is a solid option. These pistons are forged from 4032 alloy aluminum right here in the USA, designed to handle the demands of street driving and occasional track use. They come as a complete set for an 8-cylinder engine, meaning you get everything you need to get your LS back in running order.

What sets these pistons apart is the attention to detail in their construction. The 4032 aluminum alloy is well-suited for performance applications, offering a good balance of strength and lighter weight compared to cast aluminum. Wiseco also applies an ArmorGlide skirt coating, which helps reduce friction for quieter operation and offers resistance to seizing. The dome design is AS-Forged, meaning it's shaped during the forging process, and includes features for oil drain-back. This set also includes the necessary chromium alloy steel piston pins, Spirolox clips, and rings, making it a truly all-inclusive package for your engine build.

This set is designed for a 3.903-inch bore and features a 1.335-inch compression height. Remember that these pistons are not CARB approved and cannot be shipped to California. For a complete rebuild, ensure you have all other necessary components and follow the manufacturer's installation instructions.
