Wiseco Chevrolet Big Block 4.280in Bore 1.645in CH 21.00 CC Pro Tru Street Piston Set

If you're rebuilding the heart of your Chevrolet Big Block engine, a solid set of pistons is where it all starts. This Pro Tru Street piston set from Wiseco is built for performance and reliability, whether you're aiming for the street or the track. They're forged from 4032 alloy aluminum right here in the USA, giving you a well-built foundation for your engine.

What sets these pistons apart is the attention to detail. The ArmorGlide skirt coating isn't just about reducing friction for a little more power; it also helps prevent piston slap for quieter operation and resists seizure, which is crucial for longevity. The AS-Forged dome design includes features for oil drain-back, helping to manage heat and lubrication effectively. You also get a chromium alloy steel piston pin and Spirolox clips, meaning this set comes complete with everything you need for installation, making your rebuild more straightforward.

This set is designed for a 4.280-inch bore and features a 1.645-inch compression height with a 21.00 CC dish volume. Wiseco is known for making pistons that fit right and perform reliably, and this Pro Tru Street series is a popular choice for builders looking for a strong, dependable piston that won't break the bank. Remember, these are not CARB approved and cannot be shipped to California.
