Wiseco Pro Tru Street Chevy Small Block 4.030in Bore 1.560in CH 8.00 CC Piston Set

When you're rebuilding the heart of your Chevy small block engine, choosing the right pistons is crucial for performance and reliability. This set of eight Pro Tru Street pistons from Wiseco is designed for a 4.030-inch bore, a common size for many small block Chevy builds, whether you're aiming for a street-cruiser or a weekend track warrior. They are forged from 4032 alloy aluminum, a material known for its strength and durability, making them a solid choice for engines that see regular use.

Wiseco includes an ArmorGlide skirt coating on these pistons. This isn't just for looks; it helps reduce friction between the piston and cylinder wall, which can lead to quieter operation and improved longevity. The pistons also feature an AS-Forged dome with specific crown features and oil drain-backs, designed to help manage combustion and keep oil where it needs to be. You'll also find that this set comes complete with chromium alloy steel piston pins and Spirolox retaining clips, so you have all the essential components for installation right in the box.

This piston set is manufactured in Mentor, Ohio, and represents a well-built option for your engine project. Keep in mind 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.
