The Bullet Piston LS1/LS2 4.020/4 Inch Stroke Flat is a high-performance piston designed for GM’s LS-series engines, including both LS1 (5.7L) and LS2 (6.0L) V8s. This piston features a 4.020-inch bore size and is intended for engines with a 4-inch stroke, making it an ideal choice for both stock and modified LS builds. Unlike dish pistons, the flat-top design offers a more direct combustion chamber, which helps increase the compression ratio and improve power output. This piston is perfect for applications where a higher compression ratio is desired, such as in naturally aspirated or forced induction engine builds.
