Wiseco Pro Tru Street Chevy Small Block 4.060in Bore 1.125in CH -20.00 CC Piston Set

Wiseco is well-known for making strong, reliable forged pistons for performance applications. This Pro Tru Street piston set is built for Chevy small block engines and is designed to get your vehicle back on the road or down the track, no matter your budget. These pistons are forged from 4032 alloy aluminum right here in the USA, ensuring a well-built component for your engine rebuild.

Each piston in this set features an AS-Forged dome with crown features and oil drain backs, which helps manage combustion and oil flow. The ArmorGlide skirt coating is applied to reduce friction and noise, making for quieter operation and increased resistance to seizure. This set includes everything you need for a complete rebuild: the pistons themselves, chromium alloy steel piston pins, Spirolox retaining clips, and rings. The bore size is 4.060 inches, with a compression height of 1.125 inches, and a pin diameter of 0.927 inches. The dish volume is -20.00 CC, which is important for achieving your desired compression ratio.

This is a complete set of 8 pistons, ready for installation. 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.
