Product Details

Wiseco is well-known for making strong internal engine components, and these Pro Tru Street pistons are a solid choice for your Chevy 4.3L V6 build. Designed for street applications, these pistons feature a reverse dome with a -15cc dish, which helps set your compression ratio for optimal performance on the street. The 4.060 inch bore size and 1.560 inch compression height are key dimensions to consider when rebuilding your engine.

These pistons are forged, meaning they start as a solid block of aluminum that is heated and hammered into shape. This process creates a much stronger and more durable piston than cast aluminum, making them a good option for engines that see regular use. The Pro Tru Street line is built with durability and performance in mind for everyday driving, offering a good balance for your V6.

This set includes six pistons, enough for a complete engine rebuild. Please note that these pistons are not CARB approved and cannot be shipped to California. Always refer to your engine builder's specifications and the manufacturer's installation instructions for proper fitment and assembly.
