Wiseco Chevy 4.3L 4.040 Bore 1.560CH -7cc Flat Top Pro Tru Street Pistons - Set of 6

If you're rebuilding the engine in your Chevy 4.3L V6, these Wiseco Pro Tru Street pistons are a solid option. This set is designed for a 4.040 inch bore, which is a common size for a 4.3L rebuild, and features a -7cc dish volume in a flat-top design. This dish volume is important because it helps determine your compression ratio when paired with your cylinder heads and gasket thickness.

Wiseco is well-known for making durable internal engine components, and these pistons are built to handle the demands of street driving. They are forged from high-strength aluminum, which is a strong material that also helps keep overall engine weight down. The 1.560 inch compression height is also a key measurement that ensures proper piston-to-valve clearance and deck height in your engine build. This set includes six pistons, enough for a complete 6-cylinder engine.
