The Bullet Piston LS1/LS2 4.030/4 Inch Stroke Flat is a high-performance piston designed for GM's LS1 (5.7L) and LS2 (6.0L) V8 engines. It features a 4.030-inch bore size and is intended for engines with a 4-inch stroke, making it ideal for both stock and modified LS builds. The flat-top design increases the compression ratio, which is beneficial for applications where more power is desired, such as naturally aspirated or high-revving engine setups. This piston design allows for a more direct combustion chamber, optimizing airflow and combustion efficiency for improved engine performance.
