Wiseco Pro Tru Street Chevy Small Block 3.796in Bore 1.560in CH -5.40 CC Piston Set

When you're rebuilding your Chevy small block engine, this set of eight Wiseco Pro Tru Street pistons is a solid choice to get your project back on the road or down the track. These pistons are forged from 4032 alloy aluminum right here in the USA, specifically designed for street applications where durability and smooth operation are key. You get everything you need in one box for a complete rebuild: the pistons themselves, along with matching rings, chromium alloy steel piston pins, and clips.

What sets these pistons apart is the ArmorGlide skirt coating. This isn't just for looks; it's a functional feature that helps prevent 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 oil management within the cylinder. The included pins are made from a tough chromium alloy steel, built to handle the stresses of regular driving.

This set is designed for a 3.796-inch bore with a 1.560-inch compression height, and the dome volume is -5.40 CC, which will affect your final compression ratio depending on your cylinder head choice. While these are a great option for many builds, please note they are not CARB approved and cannot be shipped to California.
