Wiseco Chevy 4.3L 4.030 Bore 1.560CH -7cc Flat Top Tru Street Pistons - Set of 6

If you're rebuilding the engine in your Chevy with a 4.3L V6, these Wiseco Tru Street pistons are a solid option. This set is designed for a 4.030 inch bore, which is a common size for a performance rebuild or to bring an older engine back to spec. The pistons feature a -7cc dish, meaning they'll create a slightly lower compression ratio compared to flat-top pistons without a dish, which can be beneficial for certain camshaft profiles or if you plan on using boost. The 1.560 inch compression height is also a key measurement that ensures proper piston-to-valve clearance and deck height when paired with the correct connecting rods.

Wiseco is well-known for making strong, reliable internal engine components, and these Tru Street pistons are built for the demands of street driving while offering improved performance over stock. They are forged from high-strength aluminum, a process that makes them significantly more durable and resistant to detonation than cast pistons. This makes them a great choice for a street-driven vehicle that might see occasional spirited driving or heavier loads. The flat-top design with the dish is a smart way to manage compression for a wide range of applications.

This set includes six pistons, enough for a complete V6 engine. Remember that these pistons are not CARB approved and cannot be shipped to California. Always refer to your engine's specific service manual for detailed installation procedures and recommended clearances.
