Wiseco Pro Tru Street Chevy Big Block 4.125in Bore 1.760in CH 21.00 CC Piston Set

If you're rebuilding the heart of your Chevy Big Block engine, a solid set of pistons is crucial for performance and reliability. This Wiseco Pro Tru Street piston set is built for a 4.125-inch bore and is designed to get your vehicle back on the road or down the track with confidence. They are forged from 4032 alloy aluminum right here in the USA, ensuring a well-built component for your engine.

What sets these pistons apart is the ArmorGlide skirt coating. This isn't just for looks; it's a functional upgrade that helps resist seizure, reduces friction between the piston and cylinder wall, and contributes to quieter engine operation. The pistons also feature an AS-Forged dome with specific crown features and oil drain-backs, which are important for proper combustion and lubrication. Wiseco includes a chromium alloy steel piston pin and Spirolox clips, making this a complete package for your rebuild. The compression height is 1.760 inches with a 21.00 CC combustion chamber volume, important specs for achieving your desired compression ratio.

This set comes with everything you need to get started on your engine build, including the pistons, rings, pins, and clips. Remember that these pistons are not CARB approved and cannot be shipped to California. Always refer to the manufacturer's installation instructions for proper fitment and assembly procedures.
