Wiseco Chevy 4.3L 4.030 Bore 1.560CH -15cc Reverse Dome Pro Tru Street Pistons - Set of 6

In this set, you get six Wiseco Pro Tru Street pistons, designed for Chevy 4.3L engines. These pistons feature a 4.030 inch bore and a -15cc reverse dome dish, which is important for setting your compression ratio. The 1.560 inch compression height means they're built to work with specific connecting rod lengths, ensuring proper piston-to-valve clearance and deck height.

Wiseco is known for making well-built internal engine components, and these pistons are no exception. They're forged, meaning they start as a solid block of aluminum that's heated and hammered into shape. This forging process makes them significantly stronger and more durable than cast pistons, which is crucial for engines that see regular use or are built for performance. The reverse dome design helps manage combustion and can be beneficial for certain engine builds, particularly those aiming for a specific compression target or improved airflow in the combustion chamber.

Keep in mind these pistons are not CARB approved and cannot be shipped to California. Always refer to your engine build specifications and manufacturer's instructions to ensure these pistons are the right fit for your project.
