Wiseco Chevrolet Big Block 4.310in Bore 1.270in CH 21.00 CC Pro Tru Street Piston Set

If you're rebuilding a Chevrolet Big Block engine, this Wiseco Pro Tru Street Piston Set is a solid option. These pistons are designed for a 4.310-inch bore and feature a 1.270-inch compression height, making them suitable for a wide range of street performance applications. Wiseco forges these pistons 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 applied to reduce friction between the piston and cylinder wall, which can lead to quieter operation and improved efficiency. The dome design is AS-Forged, incorporating features for better oil drain-back and crown strength. This set comes complete with chromium alloy steel piston pins, Spirolox retaining clips, and rings, offering an all-inclusive solution for your engine build. The 21.00 CC combustion chamber volume is a key specification to consider for your compression ratio calculations.

This set includes eight pistons, along with all the necessary pins, clips, and rings to complete the rebuild. Please note 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.
